Intrusion Detection Systems (IDS's) try to detect network anomalies and maintain the secure state of network hosts. They have a long history but even nowadays their efficiency is not 100% and correlates proportionally to the number of detected false positives. Nevertheless, IDS's are considered useful especially when new community hacking tools are emerging. This allows for greater number of users to experiment with modern exploits and increases the average security risk of every online system. Snort, the de-facto industry standard open-source solution, is a mature product that has been available for over a decade.
