Answer 1

I understood that you are looking for a brief answer.

So I will give an example of Intrusion Detection System.

Actually, the duty of an intrusion detection system is to analyse the networks traffic and report the suspicious activities to the administrator. I personally suggest you to try the Security Event Manager from SoalrWinds.

It works on the network layer, to help to identify the unusually activity in the network

It also comes with the Intrusion Prevention System.
