Worth Reading: Spotlight on Tetration

My first impression: Tetration is clearly evolving and improving. It may be just me, but I think I heard more emphasis on agents and third-party sources, and less on Nexus 9K hardware. That makes sense in terms of not holding up purchase until hardware refresh time — something that previously may have deferred some/many ACI and Tetration buying decisions. Admittedly, hardware-based approaches have fewer touch points. —Pete Welcher @Netcraftsmen

Responding to Readers: Automated Design?

Deepak responded to my video on network commodization with a question:

What’s your thoughts on how Network Design itself can be Automated and validated. Also from Intent based Networking at some stage Network should re-look into itself and adjust to meet design goals or best practices or alternatively suggest the design itself in green field situation for example. APSTRA seems to be moving into this direction.

The answer to this question, as always, is—how many balloons fit in a bag? ? I think it depends on what you mean when you use the term design. If we are talking about the overlay, or traffic engineering, or even quality of service, I think we will see a rising trend towards using machine learning in network environments to help solve those problems. I am not convinced machine learning can solve these problems, in the sense of leaving humans out of the loop, but humans could set the parameters up, let the neural network learn the flows, and then let the machine adjust things over time. I tend to think this kind of work will be pretty narrow for a long time to come.

There will be stumbling blocks here that need to be Continue reading

Worth Reading: Antivirus as spyware

What does an antivirus program do? It scans every file in your device looking for *signatures*, and then uploads those files which match the signatures for further analysis by the antivirus provider. So hacking antivirus involves 2 steps: produce signatures for files you want to steal, and then exfiltrate those files. The hard work of scanning for those files is already automated by the antivirus program! —Henry Baker @RISKS

Worth Reading: Firewall Policies

Every firewall policy starts simple and with the best of intentions, only to grow and change until it no longer resembles its former self. Firewall management is so vital that it is the first requirement in the Payment Card Industry (PCI) Data Security Standard. Even if you are not required to be audited against PCI or similar standards, we can borrow some aspects to increase the security of any network. —Jamie Gillespie @APNIC

Weekend Reads 011918: IoT, Cyberthreat Thinking, and Techlash

Throughout 2016 and 2017, attacks from massive botnets made up entirely of hacked IoT devices had many experts warning of a dire outlook for Internet security. But the future of IoT doesn’t have to be so bleak. Here’s a primer on minimizing the chances that your IoT things become a security liability for you or for the Internet at large. —Krebs on Security

The cybercrime and cyber terrorism raging today are the most visible symptoms of a more pervasive problem concerning cyber security. How to establish a fair and just governance regime in cyberspace and establish international rules spark a storm of controversy. The controversy reflects the competing interests and demands of three distinct cyberspace actors: the state, the citizen, and the international community. By focusing only on one’s own interests, each actor ignores the interests of the other two, resulting in the current situation in which each sticks to its own argument and refuses to reconcile. —Hao Yeli

Deputy Attorney General Rosenstein has given talks where he proposes that tech companies decrease their communications and device security for the benefit of the FBI. In a recent talk, his idea is that tech companies just save a copy of the Continue reading

IETF 101

I will be at IETF 101 in London in March. If you have never been to an IETF before and live in the London area, this is a great chance to come see how the standardization process works, and even get involved for the long term.

Worth Reading: The software defined future of the data center

“Future proofing” was once synonymous with long-range planning—essentially, life-cycle management that enables data center facilities and hardware investments to deliver full value before redevelopment or replacement. The definition has steadily evolved to connote a flexible, resilient architecture capable of supporting accelerated business-driven digital transformation. —Paul Mercina @The Data Center Journal

On the ‘web: The Value of MANRS

Route leaks and Distributed Denial of Service (DDoS) attacks have been in the news a good deal over the last several years; but the average non-transit network operator might generally feel pretty helpless in the face of the onslaught. Perhaps you can buy a DDoS mitigation service or appliance, and deploy the ubiquitous firewall at the edge of your network, but there is not much else to be done, right? Or maybe wait on the Internet at large to “do something” about these problems by deploying some sort of BGP security. But will adopting a “secure edge,” and waiting for someone else to solve the problem, really help? @ECI
