Guidance Detect 12

Guidance Note:

The goal of an IDS is to detect cyber-attacks by analysing the signature of data packets as they traverse the network. By analysing these packets, you get real time alerts when malicious incidents happen. It can add an active protection method of adapting to the threat and blocking the traffic so the intended victim host is never reached.

------

An IDS can prevent security problems from occurring by constantly checking the content of data being moved around so that it can't be tampered with.
