If you were a black hat hacker considering targets of opportunity, a service provider network might seem very interesting. The infrastructure is critical for commerce and governmental operations. The data carried is potentially interesting and valuable. And indeed, we know that carrier networks are highly targeted. In this sponsored show with Cisco, we discuss how to think deeply about security on mission critical networks and protecting routers and other devices not behind a firewall. That means making certain that the network operating system is running exactly the code we think it is. That the devices on the network are devices we know and can trust. And then once we ve secured the network, how we can use it as a platform to deliver additional security services. Our guests are Dan Backman and Kaarthik Sivakumar of Cisco. Dan is a Technical Marketing Engineer on the Service Provider team, and Kaarthik is a Security Architect for IOS XR Engineering. We discuss the general risks service providers face and why trusted network devices are essential. Then we dive into technical details on how Cisco protects IOS XR, including the Trust Anchor Module, how to audit trusted networks, and how to build out a secure network infrastructure.

If you d heard of Cisco Tetration when it was first announced, you might have a vague memory of it being this huge rack of hardware at an eye-watering price that did some sort of analytics for massive data centers. Tetration has evolved into a platform that meets needs for organizations of many sizes. Tetration also has a bunch of genuinely interesting use cases, as Cisco has become increasingly clever about what they can do with all of that data Tetration gathers. For example, you can auto-implement a whitelist policy for application workloads. You can detect when your apps are deviating from their normal traffic patterns. You can detect software vulnerabilities. And depending on where you run Tetration, you can still get deep network performance insights, what I think of as the original Tetration value proposition. Today on this sponsored episode, we delve into what Tetration does, explore use cases, and dive into how it fits into compute environments. Our guests from Cisco are Jason Gmitter, Principal Systems Engineer; and Yogesh Kaushik, Senior Director of Product Management for Tetration.

BGP is good for keeping the Internet connected. And that s about it. BGP isn t good at optimizing the path between two endpoints, as it s more about optimizing service provider costs than traffic performance. Therefore, there are products on the market that optimize your traffic flows across the Internet despite default BGP behavior. Some of these products actually manipulate BGP, which will be the focus of our sponsored show today. Our sponsor Expereo is here to discuss their XCA and XCA Edge products with us. Joining us from Expereo are Francois Devienne, VP of Networks; and Sander Barens, VP of Commercial Development. Expereo is a managed service provider. We discuss how the company optimizes BGP to get the best out of the Internet, and explore Expereo’s XCA and XCA Edge products.
