Hello,
This page is devoted to issues related to the Linux operating system and its broadly understood security. As much as possible I will try to describe the basics of configuring, securing and managing various Linux distributions. It is true that many books on this subject as well as tutorials have already been written. But sometimes I miss to systematize this knowledge and give it in a simple, clear way so that you don’t have to spend long hours reading or looking for a solution to a problem, which then turns out to be so trivial that it takes less than fifteen minutes to solve it.
