>>We're back with a blueprint for trusted infrastructure and partnership with Dell Technologies in the cube. And we're here with Mahesh Nager, who is a consultant in the area of networking product management at Dell Technologies. Mahesh, welcome. Good to see you. >>Hey, good morning Davis. Nice to meet, Meet to you as well. >>Hey, so we've been digging into all the parts of the infrastructure stack and now we're gonna look at the all important networking components. Mahesh, when we think about networking in today's environment, we think about the core data center and we're connecting out to various locations including the cloud and both the near and the far edge. So the question is from Dell's perspective, what's unique and challenging about securing network infrastructure that we should know about? >>Yeah, so a few years ago IT security and an enterprise was primarily putting a wrapper around the data center because it was constrained to an infrastructure owned and operated by the enterprise for the most part. So putting a rapid around it like a parameter or a firewall was a sufficient response because you could basically control the one small enough control today with the distributed data, intelligent software, different systems, multi-cloud onement and asset service delivery, you know, the infrastructure for the modern era changes the way to secure the network infrastructure. In today's, you know, data driven world, it operates everywhere. And that has created and accessed everywhere so far from, you know, the centralized mono data centers of the past. The biggest challenge is how do we build the network infrastructure of the modern era that are intelligent with automation, enabling maximum flexibility and business agility without any compromise on the security. We believe that in this data era, the security transformation must accompany digital transformation. >>Yeah, that's very good. You talked about a couple of things there. Data by its very nature is distributed. There is no perimeter anymore, so you can't just, as you say, put a wrap around it. I like the way you phrase that. So when you think about cyber security resilience from a networking perspective, how do you define that? In other words, what are the basic principles that you adhere to when thinking about securing network infrastructure for your customers? >>So our belief is that cybersecurity and cybersecurity resilience, they need to be holistic. They need to be integrated, scalable, one that spans the entire enterprise and with a consistent and objective and policy implementation. So cybersecurity needs to span across all the devices and running across any application, whether the application resets on the cloud or anywhere else in the infrastructure. From a networking standpoint, what does it mean? It's again, the same principles, right? You know, in order to prevent the threat actors from accessing, changing, destroying, or stealing sensitive data, this definition holds good for networking as well. So if you look at it from a networking perspective, it's the ability to protect from and withstand attacks on the networking systems as we continue to evolve. This will also also include the ability to adapt and recover from these attacks, which is what cyber resilience aspect is all about. So cybersecurity best practices, as you know, is continuously changing the landscape, primarily because the cyber threats also continue to evolve. >>Yeah, got it. So I like that. So it's gotta be integrated, it's gotta be scalable, it's gotta be comprehensive, comprehensive and adaptable. You're saying it can't be static, >>Right? Right. So I think, you know, you had a second part of a question, you know, that says what do we, you know, what are the basic principles? You know, when you're thinking about securing network infrastructure, when you are looking at securing the network infrastructure, it revolves around core security capability of the devices that form the network. And what are these security capabilities? These are access control, software integrity and vulnerability response. When you look at access control, it's to ensure that only the authenticated users are able to access the platform and they're able to access only the kind of the assets that they're authorized to based on their user level. Now accessing a network platform like a switch or a rotor for example, is typically used for say, configuration and management of the networking switch. So user access is based on say, rules for that metal in a role based access control, whether you are security admin or a network admin or a storage admin. >>And it's imperative that logging is enabled because any of the change to the configuration is actually logged and monitored as well. We talking about software's integrity, it's the ability to ensure that the software that's running on the system has not been compromised. And, and you know, this is important because it could actually, you know, get hold of the system and you know, you could get und desired results in terms of, say validation of the images. It's, it needs to be done through in digital signature. So, so it's important that when you're talking about say, software integrity, A, you are ensuring that the platform is not compromised, you know, is not compromised, and B, that any upgrades, you know, that happens to the platform is happening through validated signature. >>Okay. And now, now you've now, so there's access control, software integrity, and I think you, you've got a third element which is i, I think response, but please continue. >>Yeah, so you know, the third myth about civil notability. So we follow the same process that's been followed by the rest of the products within the Dell product family. That's to report or identify, you know, any kind of a vulnerability that's being addressed by the Dell product security incident response team. So the networking portfolio is no different. You know, it follows the same process for identification for tri and for resolution of these vulnerabilities. And this are addressed either through patches or through new reasons via networking software. >>Yeah, got it. Okay. So I mean, you didn't say zero trust, but when you were talking about access control, you're really talking about access to only those assets that people are authorized to access. I know zero trust sometimes is a buzzword, but, but you I think gave it, you know, some clarity there. Software integrity, it's about assurance validation, your digital signature you mentioned and, and that there's been no compromise. And then how you respond to incidents in a standard way that can fit into a security framework. So outstanding description, thank you for that. But then the next question is, how does Dell networking fit into the construct of what we've been talking about Dell trusted infrastructure? >>Okay, so networking is the key element in the Dell trusted infrastructure. It prides the interconnect between the service and the storage world. And you know, it's part of any data center configuration for a trusted infrastructure. The network needs to have access control in place where only the authorized nels are able to make change to the network configuration and logging of any of those changes is also done through the logging capabilities. Additionally, we should also ensure that the configuration should provide network isolation between say the management network and the data traffic network because they need to be separate and distinct from each other. And furthermore, even if you look at the data traffic network and now you have things like say segmentation isolated segments, I know via vrs or, or some micro segmentation via partners, this allows various level of security for each of those segments. >>So it's important, you know, that, that the network infrastructure has the ability, you know, to provide all this, this services from a Dell networking security perspective, right? You know, there are multiple layers of defense, you know, both at the edge and in the network, in the hardware and in the software and essentially, you know, a set of rules and a configuration that's designed to sort of protect the integrity, confidentiality, and accessibility of the network assets. So each network security layer, it implements policies and controls as I said, you know, including send network segmentation. We do have capabilities sources, centralized management automation and capability and scalability for that matter. Now you add all of these things, you know, with the open networking standards or software, different principles and you essentially, you know, reach to the point where you know, you're looking at zero trust network access, which is essentially sort of a building block for increased cloud adoption. >>If you look at say that you know the different pillars of a zero touch architecture, you know, if you look at the device aspect, you know, we do have support for security for example, we do have say trusted platform in a trusted platform models tpms on certain offer products and you know, the physical security know, plain, simple old one lab port enabled from a user trust perspective, we know it's all done via access control days via role based access control and say capability in order to provide say remote authentication or things like say sticky Mac or Mac learning limit and so on. If you look at say a transport and a session trust layer, these are essentially, you know, how do you access, you know, this switch, you know, is it by plain or telenet or is it like secure ssh, right? And you know, when a host communicates, you know, to the switch, we do have things like self-signed or a certificate authority based certification. >>And one of the important aspect is, you know, in terms of, you know, the routing protocol, the routing protocol, say for example BGP for example, we do have the capability to support MD five authentication between the VGP peers so that there is no, you know, manages attack, you know, to the network where the routing table is compromised. And the other aspect is about second control plane is here in now, you know, it's, it's typical that if you don't have a contra plane here, you know, it could be flooded and you know, you know, the switch could be compromised by city denial service attacks. From an application trust perspective, as I mentioned, you know, we do have, you know, the application specific security rules where you could actually define, you know, the specific security rules based on the specific applications, you know, that are running within the system. >>And I did talk about, say the digital signature and the cryptographic checks and that we do for authentication and for, I mean rather for the authenticity and the validation of, you know, of the image and the BS and so on and so forth. Finally, you know, the data trust, we are looking at, you know, the network separation, you know, the network separation could happen or VRF plain old wheel Ls, you know, which can bring about say multitenancy aspects. We talk about some microsegmentation as it applies to nsx for example. The other aspect is, you know, we do have, with our own smart fabric services that's enabled in a fabric, we have a concept of c cluster security. So all of this, you know, the different pillars, they sort of make up for the zero trust infrastructure for the networking assets of an infrastructure. >>Yeah. So thank you for that. There's a, there's a lot to unpack there. You know, one of the premise, the premise really of this, this, this, this segment that we're setting up in this series is really that everything you just mentioned, or a lot of things you just mentioned used to be the responsibility of the security team. And, and the premise that we're putting forth is that because security teams are so stretched thin, you, you gotta shift a vendor community. Dell specifically is shifting a lot of those tasks to their own r and d and taking care of a lot of that. So, cuz sec op teams got a lot of other stuff to, to worry about. So my question relates to things like automation, which can help and scalability, what about those topics as it relates to networking infrastructure? >>Okay, our portfolio, >>It enables state of the automation software, you know, that enables simplifying of the design. So for example, we do have, you know, you know the fabric design center, you know, a tool that automates the design of the anti fabric and you know, from a deployment and you know, the management of the network infrastructure, there are simplicities, you know, using, you know, like Ansible s for Sonic for example, are, you know, for a better or settle and tell story. You know, we do have smart fabric services that can automate the entire fabric, you know, for a storage solution or for, you know, for one of the workloads for example. Now we do help reduce the complexity by closely integrating the management of the physical and the virtual networking infrastructure. And again, you know, we have those capabilities using Sonic or Smart Traffic services. If you look at Sonic for example, right? >>It delivers automated intent based secure containerized network and it has the ability to provide some network visibility and awareness and, and all of these things are actually valid, you know, for a modern networking infrastructure. So now if you look at Sonic, you know, it's, you know, the usage of those tools, you know, that are available, you know, within the Sonic NAS is not restricted, you know, just to the data center infrastructure is, it's a unified no, you know, that's well applicable beyond the data center. You now right up to the edge. Now if you look at our north from a smart traffic voice 10 perspective, you know, as I mentioned, we do have smart fabric services which essentially, you know, simplifies the deployment day zero. I mean rather day one, day two deployment expansion plans and the life cycle management of our conversion infrastructure and hyper and hyperconverge infrastructure solutions. And finally, in order to enable say, zero touch deployment, we do have, you know, a VP solution with our SD van capability. So these are, you know, ways by which we bring down the complexity by, you know, enhancing the automation capability using, you know, a singular loss that can expand from a data center now right to the edge. >>Great, thank you for that. Last question real quick pitch me, can you summarize from your point of view, what's the strength of the Dell networking portfolio? >>Okay, so from a Dell networking portfolio, we support capabilities at multiple layers. As I mentioned. We've talking about the physical security, for example, let's say disabling of the unused interface. Sticky Mac and trusted platform modules are the things that to go after. And when you're talking about say secure boot for example, it delivers the authenticity and the integrity of the OS 10 images at the startup. And Secure Boot also protects the startup configuration so that, you know, the startup configuration file is not compromised. And Secure port also enables the workload of prediction, for example, that is at another aspect of software image integrity validation, you know, wherein the image is validated for the digital signature in know prior to any upgrade process. And if you are looking at secure access control, we do have things like role-based access control, SSH to the switches, control plane access control that pretty do attacks and say access control from multifactor authentication. >>We do have various tech hacks for entry control to the network and things like CSAC and P IV support, you know, from a federal perspective, we do have, say logging wherein, you know, any event, any auditing capabilities can be possible by say, looking at the clog service, you know, which are pretty much in our transmitter from the devices overts for example, and last we talked about say networks, you know, say network separation and you know, these, you know, separation, you know, ensures that that is, you know, a contained say segment, you know, for a specific purpose or for the specific zone. And you know, this can be implemented by a, the micro segmentation, you know, just a plain old wheel are using virtual route of framework vr, for example. >>A lot there. I mean, I think, frankly, you know, my takeaway is you guys do the heavy lifting in a very complicated topic. So thank you so much for, for coming on the cube and explaining that in, in quite some depth. Really appreciate it. >>Thank you indeed. >>Oh, you're very welcome. Okay, in a moment I'll be back to dig into the hyper-converged infrastructure part of the portfolio and look at how when you enter the world of software defined where you're controlling servers and storage and networks via software led system, you can be sure that your infrastructure is trusted and secure. You're watching a blueprint for trusted infrastructure made possible by Dell Technologies and collaboration with the Cube, your leader in enterprise and emerging tech coverage.

>>The cybersecurity landscape continues to be one characterized by a series of point tools designed to do a very specific job, often pretty well, but the mosaic of tooling is grown over the years causing complexity in driving up costs and increasing exposures. So the game of Whackamole continues. Moreover, the way organizations approach security is changing quite dramatically. The cloud, while offering so many advantages, has also created new complexities. The shared responsibility model redefines what the cloud provider secures, for example, the S three bucket and what the customer is responsible for eg properly configuring the bucket. You know, this is all well and good, but because virtually no organization of any size can go all in on a single cloud, that shared responsibility model now spans multiple clouds and with different protocols. Now that of course includes on-prem and edge deployments, making things even more complex. Moreover, the DevOps team is being asked to be the point of execution to implement many aspects of an organization's security strategy. >>This extends to securing the runtime, the platform, and even now containers which can end up anywhere. There's a real need for consolidation in the security industry, and that's part of the answer. We've seen this both in terms of mergers and acquisitions as well as platform plays that cover more and more ground. But the diversity of alternatives and infrastructure implementations continues to boggle the mind with more and more entry points for the attackers. This includes sophisticated supply chain attacks that make it even more difficult to understand how to secure components of a system and how secure those components actually are. The number one challenge CISOs face in today's complex world is lack of talent to address these challenges. And I'm not saying that SecOps pros are not talented, They are. There just aren't enough of them to go around and the adversary is also talented and very creative, and there are more and more of them every day. >>Now, one of the very important roles that a technology vendor can play is to take mundane infrastructure security tasks off the plates of SEC off teams. Specifically we're talking about shifting much of the heavy lifting around securing servers, storage, networking, and other infrastructure and their components onto the technology vendor via r and d and other best practices like supply chain management. And that's what we're here to talk about. Welcome to the second part in our series, A Blueprint for Trusted Infrastructure Made Possible by Dell Technologies and produced by the Cube. My name is Dave Ante and I'm your host now. Previously we looked at what trusted infrastructure means and the role that storage and data protection play in the equation. In this part two of the series, we explore the changing nature of technology infrastructure, how the industry generally in Dell specifically, are adapting to these changes and what is being done to proactively address threats that are increasingly stressing security teams. >>Now today, we continue the discussion and look more deeply into servers networking and hyper-converged infrastructure to better understand the critical aspects of how one company Dell is securing these elements so that dev sec op teams can focus on the myriad new attack vectors and challenges that they faced. First up is Deepak rang Garage Power Edge security product manager at Dell Technologies. And after that we're gonna bring on Mahesh Nagar oim, who was consultant in the networking product management area at Dell. And finally, we're close with Jerome West, who is the product management security lead for HCI hyperconverged infrastructure and converged infrastructure at Dell. Thanks for joining us today. We're thrilled to have you here and hope you enjoy the program. Deepak Arage shoes powered security product manager at Dell Technologies. Deepak, great to have you on the program. Thank you. >>Thank you for having me. >>So we're going through the infrastructure stack and in part one of this series we looked at the landscape overall and how cyber has changed and specifically how Dell thinks about data protection in, in security in a manner that both secures infrastructure and minimizes organizational friction. We also hit on the storage part of the portfolio. So now we want to dig into servers. So my first question is, what are the critical aspects of securing server infrastructure that our audience should be aware of? >>Sure. So if you look at compute in general, right, it has rapidly evolved over the past couple of years, especially with trends toward software defined data centers and with also organizations having to deal with hybrid environments where they have private clouds, public cloud locations, remote offices, and also remote workers. So on top of this, there's also an increase in the complexity of the supply chain itself, right? There are companies who are dealing with hundreds of suppliers as part of their supply chain. So all of this complexity provides a lot of opportunity for attackers because it's expanding the threat surface of what can be attacked, and attacks are becoming more frequent, more severe and more sophisticated. And this has also triggered around in the regulatory and mandates around the security needs. >>And these regulations are not just in the government sector, right? So it extends to critical infrastructure and eventually it also get into the private sector. In addition to this, organizations are also looking at their own internal compliance mandates. And this could be based on the industry in which they're operating in, or it could be their own security postures. And this is the landscape in which servers they're operating today. And given that servers are the foundational blocks of the data center, it becomes extremely important to protect them. And given how complex the modern server platforms are, it's also extremely difficult and it takes a lot of effort. And this means protecting everything from the supply chain to the manufacturing and then eventually the assuring the hardware and software integrity of the platforms and also the operations. And there are very few companies that go to the lens that Dell does in order to secure the server. We truly believe in the notion and the security mentality that, you know, security should enable our customers to go focus on their business and proactively innovate on their business and it should not be a burden to them. And we heavily invest to make that possible for our customers. >>So this is really important because the premise that I set up at the beginning of this was really that I, as of security pro, I'm not a security pro, but if I were, I wouldn't want to be doing all this infrastructure stuff because I now have all these new things I gotta deal with. I want a company like Dell who has the resources to build that security in to deal with the supply chain to ensure the providence, et cetera. So I'm glad you you, you hit on that, but so given what you just said, what does cybersecurity resilience mean from a server perspective? For example, are there specific principles that Dell adheres to that are non-negotiable? Let's say, how does Dell ensure that its customers can trust your server infrastructure? >>Yeah, like when, when it comes to security at Dell, right? It's ingrained in our product, so that's the best way to put it. And security is nonnegotiable, right? It's never an afterthought where we come up with a design and then later on figure out how to go make it secure, right? Our security development life cycle, the products are being designed to counter these threats right from the big. And in addition to that, we are also testing and evaluating these products continuously to identify vulnerabilities. We also have external third party audits which supplement this process. And in addition to this, Dell makes the commitment that we will rapidly respond to any mitigations and vulnerability, any vulnerabilities and exposures found out in the field and provide mitigations and patches for in attacking manner. So this security principle is also built into our server life cycle, right? Every phase of it. >>So we want our products to provide cutting edge capabilities when it comes to security. So as part of that, we are constantly evaluating what our security model is done. We are building on it and continuously improving it. So till a few years ago, our model was primarily based on the N framework of protect, detect and rigor. And it's still aligns really well to that framework, but over the past couple of years, we have seen how computers evolved, how the threads have evolved, and we have also seen the regulatory trends and we recognize the fact that the best security strategy for the modern world is a zero trust approach. And so now when we are building our infrastructure and tools and offerings for customers, first and foremost, they're cyber resilient, right? What we mean by that is they're capable of anticipating threats, withstanding attacks and rapidly recurring from attacks and also adapting to the adverse conditions in which they're deployed. The process of designing these capabilities and identifying these capabilities however, is done through the zero press framework. And that's very important because now we are also anticipating how our customers will end up using these capabilities at there and to enable their own zero trust IT environments and IT zero trusts deployments. We have completely adapted our security approach to make it easier for customers to work with us no matter where they are in their journey towards zero trust option. >>So thank you for that. You mentioned the, this framework, you talked about zero trust. When I think about n I think as well about layered approaches. And when I think about zero trust, I think about if you, if you don't have access to it, you're not getting access, you've gotta earn that, that access and you've got layers and then you still assume that bad guys are gonna get in. So you've gotta detect that and you've gotta response. So server infrastructure security is so fundamental. So my question is, what is Dell providing specifically to, for example, detect anomalies and breaches from unauthorized activity? How do you enable fast and easy or facile recovery from malicious incidents, >>Right? What is that is exactly right, right? Breachers are bound to happen and given how complex our current environment is, it's extremely distributed and extremely connected, right? Data and users are no longer contained with an offices where we can set up a perimeter firewall and say, Yeah, everything within that is good. We can trust everything within it. That's no longer true. The best approach to protect data and infrastructure in the current world is to use a zero trust approach, which uses the principles. Nothing is ever trusted, right? Nothing is trusted implicitly. You're constantly verifying every single user, every single device, and every single access in your system at every single level of your ID environment. And this is the principles that we use on power Edge, right? But with an increased focus on providing granular controls and checks based on the principles of these privileged access. >>So the idea is that service first and foremost need to make sure that the threats never enter and they're rejected at the point of entry, but we recognize breaches are going to occur and if they do, they need to be minimized such that the sphere of damage cost by attacker is minimized so they're not able to move from one part of the network to something else laterally or escalate their privileges and cause more damage, right? So the impact radius for instance, has to be radius. And this is done through features like automated detection capabilities and automation, automated remediation capabilities. So some examples are as part of our end to end boot resilience process, we have what they call a system lockdown, right? We can lock down the configuration of the system and lock on the form versions and all changes to the system. And we have capabilities which automatically detect any drift from that lockdown configuration and we can figure out if the drift was caused to authorized changes or unauthorized changes. >>And if it is an unauthorize change can log it, generate security alerts, and we even have capabilities to automatically roll the firm where, and always versions back to a known good version and also the configurations, right? And this becomes extremely important because as part of zero trust, we need to respond to these things at machine speed and we cannot do it at a human speed. And having these automated capabilities is a big deal when achieving that zero trust strategy. And in addition to this, we also have chassis inclusion detection where if the chassis, the box, the several box is opened up, it logs alerts, and you can figure out even later if there's an AC power cycle, you can go look at the logs to see that the box is opened up and figure out if there was a, like a known authorized access or some malicious actor opening and chain something in your system. >>Great, thank you for that lot. Lot of detail and and appreciate that. I want to go somewhere else now cuz Dell has a renowned supply chain reputation. So what about securing the, the supply chain and the server bill of materials? What does Dell specifically do to track the providence of components it uses in its systems so that when the systems arrive, a customer can be a hundred percent certain that that system hasn't been compromised, >>Right? And we've talked about how complex the modern supply chain is, right? And that's no different for service. We have hundreds of confidence on the server and a lot of these form where in order to be configured and run and this former competence could be coming from third parties suppliers. So now the complexity that we are dealing with like was the end to end approach and that's where Dell pays a lot of attention into assuring the security approach approaching and it starts all the way from sourcing competence, right? And then through the design and then even the manufacturing process where we are wetting the personnel leather factories and wetting the factories itself. And the factories also have physical controls, physical security controls built into them and even shipping, right? We have GPS tagging of packages. So all of this is built to ensure supply chain security. >>But a critical aspect of this is also making sure that the systems which are built in the factories are delivered to the customers without any changes or any tapper. And we have a feature called the secure component verification, which is capable of doing this. What the feature does this, when the system gets built in a factory, it generates an inventory of all the competence in the system and it creates a cryptographic certificate based on the signatures presented to this by the competence. And this certificate is stored separately and sent to the customers separately from the system itself. So once the customers receive the system at their end, they can run out to, it generates an inventory of the competence on the system at their end and then compare it to the golden certificate to make sure nothing was changed. And if any changes are detected, we can figure out if there's an authorized change or unauthorize change. >>Again, authorized changes could be like, you know, upgrades to the drives or memory and ized changes could be any sort of temper. So that's the supply chain aspect of it and bill of metal use is also an important aspect to galing security, right? And we provide a software bill of materials, which is basically a list of ingredients of all the software pieces in the platform. So what it allows our customers to do is quickly take a look at all the different pieces and compare it to the vulnerability database and see if any of the vulner which have been discovered out in the wild affected platform. So that's a quick way of figuring out if the platform has any known vulnerabilities and it has not been patched. >>Excellent. That's really good. My last question is, I wonder if you, you know, give us the sort of summary from your perspective, what are the key strengths of Dell server portfolio from a security standpoint? I'm really interested in, you know, the uniqueness and the strong suit that Dell brings to the table, >>Right? Yeah. We have talked enough about the complexity of the environment and how zero risk is necessary for the modern ID environment, right? And this is integral to Dell powered service. And as part of that like you know, security starts with the supply chain. We already talked about the second component verification, which is a beneath feature that Dell platforms have. And on top of it we also have a silicon place platform mode of trust. So this is a key which is programmed into the silicon on the black service during manufacturing and can never be changed after. And this immutable key is what forms the anchor for creating the chain of trust that is used to verify everything in the platform from the hardware and software integrity to the boot, all pieces of it, right? In addition to that, we also have a host of data protection features. >>Whether it is protecting data at risk in news or inflight, we have self encrypting drives which provides scalable and flexible encryption options. And this couple with external key management provides really good protection for your data address. External key management is important because you know, somebody could physically steam the server walk away, but then the keys are not stored on the server, it stood separately. So that provides your action layer of security. And we also have dual layer encryption where you can compliment the hardware encryption on the secure encrypted drives with software level encryption. Inion to this we have identity and access management features like multifactor authentication, single sign on roles, scope and time based access controls, all of which are critical to enable that granular control and checks for zero trust approach. So I would say like, you know, if you look at the Dell feature set, it's pretty comprehensive and we also have the flexibility built in to meet the needs of all customers no matter where they fall in the spectrum of, you know, risk tolerance and security sensitivity. And we also have the capabilities to meet all the regulatory requirements and compliance requirements. So in a nutshell, I would say that you know, Dell Power Service cyber resident infrastructure helps accelerate zero tested option for customers. >>Got it. So you've really thought this through all the various things that that you would do to sort of make sure that your server infrastructure is secure, not compromised, that your supply chain is secure so that your customers can focus on some of the other things that they have to worry about, which are numerous. Thanks Deepak, appreciate you coming on the cube and participating in the program. >>Thank you for having >>You're welcome. In a moment I'll be back to dig into the networking portion of the infrastructure. Stay with us for more coverage of a blueprint for trusted infrastructure and collaboration with Dell Technologies on the cube, your leader in enterprise and emerging tech coverage. We're back with a blueprint for trusted infrastructure and partnership with Dell Technologies in the cube. And we're here with Mahesh Nager, who is a consultant in the area of networking product management at Dell Technologies. Mahesh, welcome, good to see you. >>Hey, good morning Dell's, nice to meet, meet to you as well. >>Hey, so we've been digging into all the parts of the infrastructure stack and now we're gonna look at the all important networking components. Mahesh, when we think about networking in today's environment, we think about the core data center and we're connecting out to various locations including the cloud and both the near and the far edge. So the question is from Dell's perspective, what's unique and challenging about securing network infrastructure that we should know about? >>Yeah, so few years ago IT security and an enterprise was primarily putting a wrapper around data center out because it was constrained to an infrastructure owned and operated by the enterprise for the most part. So putting a rapid around it like a parameter or a firewall was a sufficient response because you could basically control the environment and data small enough control today with the distributed data, intelligent software, different systems, multi-cloud environment and asset service delivery, you know, the infrastructure for the modern era changes the way to secure the network infrastructure In today's, you know, data driven world, it operates everywhere and data has created and accessed everywhere so far from, you know, the centralized monolithic data centers of the past. The biggest challenge is how do we build the network infrastructure of the modern era that are intelligent with automation enabling maximum flexibility and business agility without any compromise on the security. We believe that in this data era, the security transformation must accompany digital transformation. >>Yeah, that's very good. You talked about a couple of things there. Data by its very nature is distributed. There is no perimeter anymore, so you can't just, as you say, put a rapper around it. I like the way you phrase that. So when you think about cyber security resilience from a networking perspective, how do you define that? In other words, what are the basic principles that you adhere to when thinking about securing network infrastructure for your customers? >>So our belief is that cybersecurity and cybersecurity resilience, they need to be holistic, they need to be integrated, scalable, one that span the entire enterprise and with a co and objective and policy implementation. So cybersecurity needs to span across all the devices and running across any application, whether the application resets on the cloud or anywhere else in the infrastructure. From a networking standpoint, what does it mean? It's again, the same principles, right? You know, in order to prevent the threat actors from accessing changing best destroy or stealing sensitive data, this definition holds good for networking as well. So if you look at it from a networking perspective, it's the ability to protect from and withstand attacks on the networking systems as we continue to evolve. This will also include the ability to adapt and recover from these attacks, which is what cyber resilience aspect is all about. So cybersecurity best practices, as you know, is continuously changing the landscape primarily because the cyber threats also continue to evolve. >>Yeah, got it. So I like that. So it's gotta be integrated, it's gotta be scalable, it's gotta be comprehensive, comprehensive and adaptable. You're saying it can't be static, >>Right? Right. So I think, you know, you had a second part of a question, you know, that says what do we, you know, what are the basic principles? You know, when you think about securing network infrastructure, when you're looking at securing the network infrastructure, it revolves around core security capability of the devices that form the network. And what are these security capabilities? These are access control, software integrity and vulnerability response. When you look at access control, it's to ensure that only the authenticated users are able to access the platform and they're able to access only the kind of the assets that they're authorized to based on their user level. Now accessing a network platform like a switch or a rotor for example, is typically used for say, configuration and management of the networking switch. So user access is based on say roles for that matter in a role based access control, whether you are a security admin or a network admin or a storage admin. >>And it's imperative that logging is enable because any of the change to the configuration is actually logged and monitored as that. Talking about software's integrity, it's the ability to ensure that the software that's running on the system has not been compromised. And, and you know, this is important because it could actually, you know, get hold of the system and you know, you could get UND desire results in terms of say validation of the images. It's, it needs to be done through say digital signature. So, so it's important that when you're talking about say, software integrity, a, you are ensuring that the platform is not compromised, you know, is not compromised and be that any upgrades, you know, that happens to the platform is happening through say validated signature. >>Okay. And now, now you've now, so there's access control, software integrity, and I think you, you've got a third element which is i I think response, but please continue. >>Yeah, so you know, the third one is about civil notability. So we follow the same process that's been followed by the rest of the products within the Dell product family. That's to report or identify, you know, any kind of a vulnerability that's being addressed by the Dell product security incident response team. So the networking portfolio is no different, you know, it follows the same process for identification for tri and for resolution of these vulnerabilities. And these are addressed either through patches or through new reasons via networking software. >>Yeah, got it. Okay. So I mean, you didn't say zero trust, but when you were talking about access control, you're really talking about access to only those assets that people are authorized to access. I know zero trust sometimes is a buzzword, but, but you I think gave it, you know, some clarity there. Software integrity, it's about assurance validation, your digital signature you mentioned and, and that there's been no compromise. And then how you respond to incidents in a standard way that can fit into a security framework. So outstanding description, thank you for that. But then the next question is, how does Dell networking fit into the construct of what we've been talking about Dell trusted infrastructure? >>Okay, so networking is the key element in the Dell trusted infrastructure. It provides the interconnect between the service and the storage world. And you know, it's part of any data center configuration for a trusted infrastructure. The network needs to have access control in place where only the authorized nels are able to make change to the network configuration and logging off any of those changes is also done through the logging capabilities. Additionally, we should also ensure that the configuration should provide network isolation between say the management network and the data traffic network because they need to be separate and distinct from each other. And furthermore, even if you look at the data traffic network and now you have things like segmentation isolated segments and via VRF or, or some micro segmentation via partners, this allows various level of security for each of those segments. So it's important you know, that, that the network infrastructure has the ability, you know, to provide all this, this services from a Dell networking security perspective, right? >>You know, there are multiple layer of defense, you know, both at the edge and in the network in this hardware and in the software and essentially, you know, a set of rules and a configuration that's designed to sort of protect the integrity, confidentiality, and accessibility of the network assets. So each network security layer, it implements policies and controls as I said, you know, including send network segmentation. We do have capabilities sources, centralized management automation and capability and scalability for that matter. Now you add all of these things, you know, with the open networking standards or software, different principles and you essentially, you know, reach to the point where you know, you're looking at zero trust network access, which is essentially sort of a building block for increased cloud adoption. If you look at say that you know the different pillars of a zero trust architecture, you know, if you look at the device aspect, you know, we do have support for security for example, we do have say trust platform in a trusted platform models tpms on certain offer products and you know, the physical security know plain, simple old one love port enable from a user trust perspective, we know it's all done via access control days via role based access control and say capability in order to provide say remote authentication or things like say sticky Mac or Mac learning limit and so on. >>If you look at say a transport and decision trust layer, these are essentially, you know, how do you access, you know, this switch, you know, is it by plain hotel net or is it like secure ssh, right? And you know, when a host communicates, you know, to the switch, we do have things like self-signed or is certificate authority based certification. And one of the important aspect is, you know, in terms of, you know, the routing protocol, the routing protocol, say for example BGP for example, we do have the capability to support MD five authentication between the b g peers so that there is no, you know, manages attack, you know, to the network where the routing table is compromised. And the other aspect is about second control plane is here, you know, you know, it's, it's typical that if you don't have a control plane here, you know, it could be flooded and you know, you know, the switch could be compromised by city denial service attacks. >>From an application test perspective, as I mentioned, you know, we do have, you know, the application specific security rules where you could actually define, you know, the specific security rules based on the specific applications, you know, that are running within the system. And I did talk about, say the digital signature and the cryptographic check that we do for authentication and for, I mean rather for the authenticity and the validation of, you know, of the image and the BS and so on and so forth. Finally, you know, the data trust, we are looking at, you know, the network separation, you know, the network separation could happen or VRF plain old wheel Ls, you know, which can bring about sales multi 10 aspects. We talk about some microsegmentation as it applies to nsx for example. The other aspect is, you know, we do have, with our own smart fabric services that's enabled in a fabric, we have a concept of c cluster security. So all of this, you know, the different pillars, they sort of make up for the zero trust infrastructure for the networking assets of an infrastructure. >>Yeah. So thank you for that. There's a, there's a lot to unpack there. You know, one of the premise, the premise really of this, this, this, this segment that we're setting up in this series is really that everything you just mentioned, or a lot of things you just mentioned used to be the responsibility of the security team. And, and the premise that we're putting forth is that because security teams are so stretched thin, you, you gotta shift the vendor community. Dell specifically is shifting a lot of those tasks to their own r and d and taking care of a lot of that. So, cuz scop teams got a lot of other stuff to, to worry about. So my question relates to things like automation, which can help and scalability, what about those topics as it relates to networking infrastructure? >>Okay, our >>Portfolio, it enables state of the automation software, you know, that enables simplifying of the design. So for example, we do have, you know, you know the fabric design center, you know, a tool that automates the design of the fabric and you know, from a deployment and you know, the management of the network infrastructure that are simplicities, you know, using like Ansible s for Sonic for example are, you know, for a better sit and tell story. You know, we do have smart fabric services that can automate the entire fabric, you know, for a storage solution or for, you know, for one of the workloads for example. Now we do help reduce the complexity by closely integrating the management of the physical and the virtual networking infrastructure. And again, you know, we have those capabilities using Sonic or Smart Traffic services. If you look at Sonic for example, right? >>It delivers automated intent based secure containerized network and it has the ability to provide some network visibility and Avan has and, and all of these things are actually valid, you know, for a modern networking infrastructure. So now if you look at Sonic, you know, it's, you know, the usage of those tools, you know, that are available, you know, within the Sonic no is not restricted, you know, just to the data center infrastructure is, it's a unified no, you know, that's well applicable beyond the data center, you know, right up to the edge. Now if you look at our north from a smart traffic OS 10 perspective, you know, as I mentioned, we do have smart traffic services which essentially, you know, simplifies the deployment day zero, I mean rather day one, day two deployment expansion plans and the lifecycle management of our conversion infrastructure and hyper and hyper conversion infrastructure solutions. And finally, in order to enable say, zero touch deployment, we do have, you know, a VP solution with our SD van capability. So these are, you know, ways by which we bring down the complexity by, you know, enhancing the automation capability using, you know, a singular loss that can expand from a data center now right to the edge. >>Great, thank you for that. Last question real quick, just pitch me, what can you summarize from your point of view, what's the strength of the Dell networking portfolio? >>Okay, so from a Dell networking portfolio, we support capabilities at multiple layers. As I mentioned, we're talking about the physical security for examples, say disabling of the unused interface. Sticky Mac and trusted platform modules are the things that to go after. And when you're talking about say secure boot for example, it delivers the authenticity and the integrity of the OS 10 images at the startup. And Secure Boot also protects the startup configuration so that, you know, the startup configuration file is not compromised. And Secure port also enables the workload of prediction, for example, that is at another aspect of software image integrity validation, you know, wherein the image is data for the digital signature, you know, prior to any upgrade process. And if you are looking at secure access control, we do have things like role based access control, SSH to the switches, control plane access control that pre do tags and say access control from multifactor authentication. >>We do have various tech ads for entry control to the network and things like CSE and PRV support, you know, from a federal perspective we do have say logging wherein, you know, any event, any auditing capabilities can be possible by say looking at the clog service, you know, which are pretty much in our transmitter from the devices overts for example, and last we talked about say network segment, you know, say network separation and you know, these, you know, separation, you know, ensures that are, that is, you know, a contained say segment, you know, for a specific purpose or for the specific zone and, you know, just can be implemented by a, a micro segmentation, you know, just a plain old wheel or using virtual route of framework VR for example. >>A lot there. I mean I think frankly, you know, my takeaway is you guys do the heavy lifting in a very complicated topic. So thank you so much for, for coming on the cube and explaining that in in quite some depth. Really appreciate it. >>Thank you indeed. >>Oh, you're very welcome. Okay, in a moment I'll be back to dig into the hyper-converged infrastructure part of the portfolio and look at how when you enter the world of software defined where you're controlling servers and storage and networks via software led system, you could be sure that your infrastructure is trusted and secure. You're watching a blueprint for trusted infrastructure made possible by Dell Technologies and collaboration with the cube, your leader in enterprise and emerging tech coverage, your own west product management security lead at for HCI at Dell Technologies hyper-converged infrastructure. Jerome, welcome. >>Thank you Dave. >>Hey Jerome, in this series of blueprint for trusted infrastructure, we've been digging into the different parts of the infrastructure stack, including storage servers and networking, and now we want to cover hyperconverged infrastructure. So my first question is, what's unique about HCI that presents specific security challenges? What do we need to know? >>So what's unique about hyper-converge infrastructure is the breadth of the security challenge. We can't simply focus on a single type of IT system. So like a server or storage system or a virtualization piece of software, software. I mean HCI is all of those things. So luckily we have excellent partners like VMware, Microsoft, and internal partners like the Dell Power Edge team, the Dell storage team, the Dell networking team, and on and on. These partnerships in these collaborations are what make us successful from a security standpoint. So let me give you an example to illustrate. In the recent past we're seeing growing scope and sophistication in supply chain attacks. This mean an attacker is going to attack your software supply chain upstream so that hopefully a piece of code, malicious code that wasn't identified early in the software supply chain is distributed like a large player, like a VMware or Microsoft or a Dell. So to confront this kind of sophisticated hard to defeat problem, we need short term solutions and we need long term solutions as well. >>So for the short term solution, the obvious thing to do is to patch the vulnerability. The complexity is for our HCI portfolio. We build our software on VMware, so we would have to consume a patch that VMware would produce and provide it to our customers in a timely manner. Luckily VX rail's engineering team has co engineered a release process with VMware that significantly shortens our development life cycle so that VMware would produce a patch and within 14 days we will integrate our own code with the VMware release we will have tested and validated the update and we will give an update to our customers within 14 days of that VMware release. That as a result of this kind of rapid development process, VHA had over 40 releases of software updates last year for a longer term solution. We're partnering with VMware and others to develop a software bill of materials. We work with VMware to consume their software manifest, including their upstream vendors and their open source providers to have a comprehensive list of software components. Then we aren't caught off guard by an unforeseen vulnerability and we're more able to easily detect where the software problem lies so that we can quickly address it. So these are the kind of relationships and solutions that we can co engineer with effective collaborations with our, with our partners. >>Great, thank you for that. That description. So if I had to define what cybersecurity resilience means to HCI or converged infrastructure, and to me my takeaway was you gotta have a short term instant patch solution and then you gotta do an integration in a very short time, you know, two weeks to then have that integration done. And then longer term you have to have a software bill of materials so that you can ensure the providence of all the components help us. Is that a right way to think about cybersecurity resilience? Do you have, you know, a additives to that definition? >>I do. I really think that's site cybersecurity and resilience for hci because like I said, it has sort of unprecedented breadth across our portfolio. It's not a single thing, it's a bit of everything. So really the strength or the secret sauce is to combine all the solutions that our partner develops while integrating them with our own layer. So let me, let me give you an example. So hci, it's a, basically taking a software abstraction of hardware functionality and implementing it into something called the virtualized layer. It's basically the virtual virtualizing hardware functionality, like say a storage controller, you could implement it in hardware, but for hci, for example, in our VX rail portfolio, we, our Vxl product, we integrated it into a product called vsan, which is provided by our partner VMware. So that portfolio of strength is still, you know, through our, through our partnerships. >>So what we do, we integrate these, these security functionality and features in into our product. So our partnership grows to our ecosystem through products like VMware, products like nsx, Horizon, Carbon Black and vSphere. All of them integrate seamlessly with VMware and we also leverage VMware's software, part software partnerships on top of that. So for example, VX supports multifactor authentication through vSphere integration with something called Active Directory Federation services for adfs. So there's a lot of providers that support adfs including Microsoft Azure. So now we can support a wide array of identity providers such as Off Zero or I mentioned Azure or Active Directory through that partnership. So we can leverage all of our partners partnerships as well. So there's sort of a second layer. So being able to secure all of that, that provides a lot of options and flexibility for our customers. So basically to summarize my my answer, we consume all of the security advantages of our partners, but we also expand on them to make a product that is comprehensively secured at multiple layers from the hardware layer that's provided by Dell through Power Edge to the hyper-converged software that we build ourselves to the virtualization layer that we get through our partnerships with Microsoft and VMware. >>Great, I mean that's super helpful. You've mentioned nsx, Horizon, Carbon Black, all the, you know, the VMware component OTH zero, which the developers are gonna love. You got Azure identity, so it's really an ecosystem. So you may have actually answered my next question, but I'm gonna ask it anyway cuz you've got this software defined environment and you're managing servers and networking and storage with this software led approach, how do you ensure that the entire system is secure end to end? >>That's a really great question. So the, the answer is we do testing and validation as part of the engineering process. It's not just bolted on at the end. So when we do, for example, VxRail is the market's only co engineered solution with VMware, other vendors sell VMware as a hyper converged solution, but we actually include security as part of the co-engineering process with VMware. So it's considered when VMware builds their code and their process dovetails with ours because we have a secure development life cycle, which other products might talk about in their discussions with you that we integrate into our engineering life cycle. So because we follow the same framework, all of the, all of the codes should interoperate from a security standpoint. And so when we do our final validation testing when we do a software release, we're already halfway there in ensuring that all these features will give the customers what we promised. >>That's great. All right, let's, let's close pitch me, what would you say is the strong suit summarize the, the strengths of the Dell hyper-converged infrastructure and converged infrastructure portfolio specifically from a security perspective? Jerome? >>So I talked about how hyper hyper-converged infrastructure simplifies security management because basically you're gonna take all of these features that are abstracted in in hardware, they're now abstracted in the virtualization layer. Now you can manage them from a single point of view, whether it would be, say, you know, in for VX rail would be b be center, for example. So by abstracting all this, you make it very easy to manage security and highly flexible because now you don't have limitations around a single vendor. You have a multiple array of choices and partnerships to select. So I would say that is the, the key to making it to hci. Now, what makes Dell the market leader in HCI is not only do we have that functionality, but we also make it exceptionally useful to you because it's co engineered, it's not bolted on. So I gave the example of spo, I gave the example of how we, we modify our software release process with VMware to make it very responsive. >>A couple of other features that we have specific just to HCI are digitally signed LCM updates. This is an example of a feature that we have that's only exclusive to Dell that's not done through a partnership. So we digitally signed our software updates so the user can be sure that the, the update that they're installing into their system is an authentic and unmodified product. So we give it a Dell signature that's invalidated prior to installation. So not only do we consume the features that others develop in a seamless and fully validated way, but we also bolt on our own a specific HCI security features that work with all the other partnerships and give the user an exceptional security experience. So for, for example, the benefit to the customer is you don't have to create a complicated security framework that's hard for your users to use and it's hard for your system administrators to manage it all comes in a package. So it, it can be all managed through vCenter, for example, or, and then the specific hyper, hyper-converged functions can be managed through VxRail manager or through STDC manager. So there's very few pains of glass that the, the administrator or user ever has to worry about. It's all self contained and manageable. >>That makes a lot of sense. So you've got your own infrastructure, you're applying your best practices to that, like the digital signatures, you've got your ecosystem, you're doing co-engineering with the ecosystems, delivering security in a package, minimizing the complexity at the infrastructure level. The reason Jerome, this is so important is because SecOps teams, you know, they gotta deal with cloud security, they gotta deal with multiple clouds. Now they have their shared responsibility model going across multiple cl. They got all this other stuff that they have to worry, they gotta secure the containers and the run time and and, and, and, and the platform and so forth. So they're being asked to do other things. If they have to worry about all the things that you just mentioned, they'll never get, you know, the, the securities is gonna get worse. So what my takeaway is, you're removing that infrastructure piece and saying, Okay guys, you now can focus on those other things that is not necessarily Dell's, you know, domain, but you, you know, you can work with other partners to and your own teams to really nail that. Is that a fair summary? >>I think that is a fair summary because absolutely the worst thing you can do from a security perspective is provide a feature that's so unusable that the administrator disables it or other key security features. So when I work with my partners to define, to define and develop a new security feature, the thing I keep foremost in mind is, will this be something our users want to use and our administrators want to administer? Because if it's not, if it's something that's too difficult or onerous or complex, then I try to find ways to make it more user friendly and practical. And this is a challenge sometimes because we are, our products operate in highly regulated environments and sometimes they have to have certain rules and certain configurations that aren't the most user friendly or management friendly. So I, I put a lot of effort into thinking about how can we make this feature useful while still complying with all the regulations that we have to comply with. And by the way, we're very successful in a highly regulated space. We sell a lot of VxRail, for example, into the Department of Defense and banks and, and other highly regulated environments and we're very successful there. >>Excellent. Okay, Jerome, thanks. We're gonna leave it there for now. I'd love to have you back to talk about the progress that you're making down the road. Things always, you know, advance in the tech industry and so would appreciate that. >>I would look forward to it. Thank you very much, Dave. >>You're really welcome. In a moment I'll be back to summarize the program and offer some resources that can help you on your journey to secure your enterprise infrastructure. I wanna thank our guests for their contributions in helping us understand how investments by a company like Dell can both reduce the need for dev sec up teams to worry about some of the more fundamental security issues around infrastructure and have greater confidence in the quality providence and data protection designed in to core infrastructure like servers, storage, networking, and hyper-converged systems. You know, at the end of the day, whether your workloads are in the cloud, on prem or at the edge, you are responsible for your own security. But vendor r and d and vendor process must play an important role in easing the burden faced by security devs and operation teams. And on behalf of the cube production content and social teams as well as Dell Technologies, we want to thank you for watching a blueprint for trusted infrastructure.
