The number of Intrusion Detection Systems (IDSs) is large and growing. Most IDSs are signature based, which means that they include signatures for some collection of known attacks, and monitor an event stream looking for instances of any signature in their collection. There is an enormous duplication of effort within the IDS community, as each newly discovered attack requires independent specification for each IDS. Sharing of signature collections has obvious advantages for the IDS community as a whole, mainly by allowing better allocation of scarce resources (developers and researchers) and supporting peer review of signature collections, which can lead to better signatures and better detectors. Snort is an IDS with a large published collection of signatures.
