Although Linux is often considered to be superior to Windows and macOS with regard to security, it is not without its own security flaws. I, personally, would posit that Linux can be more secure than other platforms, but it requires proper configuration and can still be undone by a loose nut behind the keyboard. Virtualization.

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.
