What the intrusion prevention system is for and how it works?
Network intrusion is undesirable network traffic impacting on functionality or security of the victim-host. Its purpose is mostly to get illegitimate access or/and to exploit fragile data. A typical attribute of such intrusions is their apparent legitimacy and it is difficult to uncover such traffic and filter it simply out by traffic rules. Let us use DoS intrusion (Denial of Service) as an example. In this type of intrusion, too many connections are established on a port to use up the system resources of the server application so that no other users can connect there. However, the firewall considers this act only as an access to an allowed port.
Therefore, sophisticated analysis of network traffic is needed here to detect network intrusions. Network intrusion detection systems use databases of known intrusions (this is similar to antivirus programs using databases of known viruses). Thanks to regular update of the database, new intrusion types are also recognized.
Intrusion detection is performed before application of traffic rules which avoids intervention of traffic rules with the detection process.
