Suricata: Free intrusion detection & prevention engine
The Open Information Security Foundation (OISF) has released version 1.0 of its open source intrusion detection and prevention engine – Suricata. The first stable release includes a number of improvements and new features over the previous development releases, such as support for DCERPC over UDP and the tag keyword. Unlike Snort, another popular open source network intrusion prevention and detection system, Suricata runs multi-threaded and offers a number of advanced configuration options.
The OISF is funded by several US agencies, such as the Department of Homeland Security's Directorate for Science and Technology HOST program (Homeland Open Security Technology) and various members of the OISF Consortium, including a number of specialist IT security companies.
More details about the release can be found in the mailing list announcement and provided documentation. Suricata 1.0 source is available to download from the foundation's web site and is licensed under version 2 of the GNU General Public License (GPLv2).
