An IPS can be considered as an intrusion prevention mechanism.

Intrusion detection and prevention systems provide us with the first line of defense against harmful intruders. We must not consider an IPS as a substitute for IDS (it is a different case if the same tool provides all the functions of both instruments). IPS and IDS provide the control and visibility required by any company to protect their infrastructure from attack and take-over.

One of the most important factors to take in consideration when using an IPS / IDS is a correct insertion into the infrastructure through distribution. Improper implementation will lead to a huge network slowdown and improper management.

The main function of an IPS is therefore to identify the harmful activities, to try to block or cease their activity, to report the activity.

The IPS, therefore, provides a valid security prevention. The IPS detects an intrusion into network traffic.

An IPS should not be confused or confused as a substitute for another network security measure, in particular: the firewall. The task of a firewall is to restrict access to a network/system and is generally unable to detect and prevent an intrusion.
