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. Aside from a Windows VM I maintain for the occasional thing I can’t do effectively on Linux or OS X, I haven’t worked with Windows in any significant capacity in quite a while.

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.

The problem is that threat actors are able to get through the castle gates (firewalls) and once in, are able to evade the castle guards (IPS). Cisco EPGs can be a physical server, a virtual machine, a Linux container, or even a mainframe. Microsegmentation will fix this. It uses a new construct they call End Point Groups (EPG).

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.

Plus, by default, the administrator account on Windows computers doesn’t lock out.
