How to use the PAM Security System?

Question

linux

How to switch from one system to another. I'm watching a security video on Centos7. https://www.youtube.com/watch?v=yOCRGTFTShM and it somehow strangely shows how it goes from Linuxbox to WordPress. is it some kind of remote machine? And how can I do the same? who went through it? I am new to this business, just started to learn and faced such difficulties that the video does not show how to solve it. so please help me :)

Answer 1

And what is the task? PAM is an applied thing, like everything in Linux, in general, it is intended to solve some problem, and not by itself.
