Suricata is a network intrusion detection and prevention engine developed by the Open Information Security Foundation and its supporting vendors. The engine is multi-threaded and has native IPv6 support. It's capable of loading existing Snort rules and signatures and supports the Barnyard and Barnyard2 tools.

Changes: This release adds a TLS/SSL handshake parser, an HTTP user agent keyword, experimental rule reloading support, AF_PACKET bpf support and packet loss counters, Napatech hardware support, a configuration test mode, a rule analyzer, and on-the-fly MD5 calculation and matching for files. Performance and scalability have been improved.
