I highly recommend you read the entire post, but in short the five skills Matt recommends are software skills (which includes configuration management and software development tools like Git ), Linux, deep protocol knowledge, hypervisor and container networking, and IPv6. Operating Systems/Applications. What does this mean?

It was good to read this post on Cumulus Linux first impressions by Jeremy Stretch. I’m a fan of Cumulus, but I’m admittedly a Linux guy (see here ) so you might say I’m a bit biased. Jeremy is a “hard-core” networking professional, and so hearing his feedback on Cumulus Linux was, in my opinion, useful.

Anthony Burke gives a little bit of a sneak peek at some functionality from the upcoming v3 release of PowerNSX: searching NSX Distributed Firewall (DFW) rules. The article supplies lots of useful information, but I really would’ve liked some concrete examples of how to glue these pieces together. Operating Systems/Applications.

OK, now that I’ve mentioned Skydive, I can talk about this article that provides an example of functional SDN testing with Terraform and Skydive. Terraform is used to turn up OpenStack infrastructure, and Skydive (via connections into Neutron and OpenContrail, in this example) is used to validate SDN functionality. What’s that?

In the event you’re interested in an idea of how much latency the use of in-kernel hypervisor firewalling (such as that offered by VMware NSX) adds, have a look at this article by Sean Howard. Operating Systems/Applications. It’s a good post, well worth reading (in my opinion). Servers/Hardware. Nothing this time around.

This post provides some examples of shared control planes (and thus shared failure domains) within networking. In this post , Jakub Sitnicki digs way deep into the Linux kernel to uncover the answer to the question, “Why are there no entries in the conntrack table for SYN packets dropped by the firewall?”

My example of hitting random keys and forcing the password manger to pop open illustrates the topic of this episode.

We all know that security is more than just a host-based firewall, but a host-based firewall can be part of an overall security strategy. This article provides a good introductory overview of Linux iptables commands for configuring host-based firewall rules on your Linux systems.

The use of VMware NSX for microsegmentation is a really popular use case, and so the topic of scripting distributed firewall (DFW) rules often comes up. Operating Systems/Applications.

Living off the Land (LoL) is an attack where files already on your machine, ie your operating system, are used against you. So I started thinking about other ways to hide messages or even how to get malware onto a system without it being detected. Like all the unused files within your operating system?

This time around, the content is a bit heavier on cloud management and applications/operating systems, but still lots of good content all the way around (I hope, anyway). First, here’s a workaround to the fact that vCA doesn’t (yet) do cloud-init, which makes injecting SSH keys into Linux instances a bit difficult. Networking.

I’m reminded of when I trained to use Kali Linux. Say, for example, you are in oil and gas. Rather than -- I need a firewall -- maybe ATT&CK suggests a specific type of firewall. And maybe it’s not the firewall you currently have. Kali is a swiss army knife of useful tools. Duff: Yeah.
