In this long blog I try to sum-up some features which you should disable before running MikroTik in any environment. First of all is an `backup` interface, so in case you lock yourself up, you will always have a way to login.

MikroTik has a simple interface for managing certificates, but lacks the ability to notify you when such cert expires. For this reason I created a simple script insipired by forum question and modified for my purpose.
