What is the difference between IDS and IPS?

Hello Experts.

What is the difference between IDS and IPS?

IDS stands for intrusion detection system, this is usually passive, only listen in the network looking for patterns or signatures of attacks an it compare those signatures with a database.

IPS stands for Intrusion Prevention System that is more reactive, because it listens on the traffic and is able to react when an attack is happening, for example sending reset to TCP sessions trying to close multiple open sessions or even generating automatic policies in firewalls to contain an attack.

Intrusion prevention system… What are the methods for addressing false positives?

Before it was with anomalies detection. (This was more with statistics)

Now using machine learning you can do it more automatic. (This is by learning what are the more common behavior, something out of this behavior is subject of analysis)
