Show 385: Getting Inside Cisco Tetration (Sponsored)
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.

Is Networking Complex/Hard ?
Its not complicated (natch). Its distributed. And we don’t have visibility to know. Distributed Systems What makes networking hard ? A network is a distributed system where state must be shared between devices that are unreliably connected. Its a fallacy that a network will ever be reliable or predictable.

Security Research is Critical to Protect the Open Internet
On, April 10, 2018 I joined over fifty like-minded individuals signing a letter emphasizing the importance of security research. The letter renounces a number of recent lawsuits, such as Keeper v. Goodlin and River City Media v. Kromtech, against security researchers and journalists and highlights the importance of the work they are doing to defend against a rapidly increasing number of security threats.
Security research, sometimes called white-hat hacking, is a practice by ethical hackers whereby they legally find flaws in information systems and report them to the creators of those systems. The ability to find and report these vulnerabilities before other bad actors can manipulate them has become increasingly important, especially in the context of the Internet of Things (IoT).
As we discussed at Enhancing IoT Security in Ottawa, Canada this week, Internet-connected devices offer great promise, but they can also create a host of security issues. It is crucial that we continue to encourage individuals to seek out and correct flaws in these devices as their application and use grows.
As Olaf Kolkman, Chief Internet Technology Officer at the Internet Society, wrote recently, security researchers are helping to make the Internet more secure. Collaboration between those Continue reading

5 Steps for Government Cybersecurity
As cyberthreats escalate, government agencies around the world need to take action to mitigate the risk to their data.
Video: Automatic Diagramming with PowerNSX
Here's a trick question: how often do your Visio diagrams match what's really implemented in your network?
Wouldn't it be great to be able to create or modify them on-the-fly based on what's really configured in the network? That's exactly what Anthony Burke demonstrated in the PowerNSX part of PowerShell for Networking Engineers webinar (source code).
You’ll need at least free ipSpace.net subscription to watch the video.
NetDevOpEd: Open source principles give the workplace soul
If you’ve been tuning into Cumulus content lately, you probably know all about our initiative to bring S.O.U.L (Simple, Open, Untethered Linux) into networking — and for the uninitiated, feel free to check out our S.O.U.L page to learn all about the movement! It’s clear that our company and technology have S.O.U.L, but what does that look like in the office? Anyone who’s spent time at our office, in our bootcamps, with our people, etc. can feel that Cumulus Networks has “soul,” and this time we’re not talking about the acronym. We’ve got a passion, substance, life and feeling that pulses throughout our space like a funky bass line.
How do I know this? Well, I work at Cumulus, but it’s more than that. My former employers (before I started working at Cumulus Networks) are pretty varied, ranging from a restaurant to a university, but all of those jobs had one thing in common — they had no soul. To these Pink Floyd-ian businesses, employees were just cogs in the machine meant to forfeit passion for profit. Each day I dragged myself out of bed, drudged Continue reading
Successful First Event in the Canadian Multistakeholder Process – Enhancing IoT Security Series
On April 4, 2018, over 80 individuals met in Ottawa and virtually via livestream for the first event in the Canadian Multistakeholder Process – Enhancing IoT Security series. Participants represented a wide-range of stakeholder groups, including government, academia, public interest, and industry representatives. Two Internet Society Organization Members, the Canadian Internet Registration Authority and CANARIE, as well as Innovation, Science and Economic Development Canada and the Canadian Internet Policy and Public Interest Clinic were partners for this event. IoT security is a complex issue that requires all stakeholders to cooperate and participate in the development of solutions, and we were pleased to have such truly multistakeholder representation.
The event kicked off with an interactive presentation from Larry Strickling, Executive Director of the Collaborative Governance Project. Strickling provided an overview of the multistakeholder process and facilitated a discussion among participants to determine ground rules and define what constitutes consensus. Participants, both those remote and in person, outlined over a dozen rules and three key metrics for determining consensus, which will be used throughout the entirety of the project.
In the morning, participants heard from a series of speakers who presented on IoT security and risk, the balance between IoT’s technological Continue reading
