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.
