Versie 3.2 van Suricata is uitgekomen. Suricata is een opensource-network intrusion detection system (IDS), intrusion prevention system (IPS) en network security monitoring engine. Het kan worden gebruikt om netwerkverkeer te monitoren en een systeembeheerder een waarschuwing te geven als er iets verdachts wordt gesignaleerd. De ontwikkeling wordt overzien door de Open Information Security Foundation, met hulp van de community en diverse fabrikanten. De met het op json gebaseerd logsysteem Eve verzamelde data kan onder meer met Logstash worden gebruikt om zo informatie grafisch weer te geven. In deze uitgave zijn de volgende verbeteringen aangebracht:
Suricata 3.2 available!
Suricata 3.2 comes with some new features that can help a Meerkat to stay awake when on a guard watch. The support of industrial networks has been greatly improved with the addition of two new protocols, DNP3 and CIP/ENIP. But we can’t forget the improvements on the TLS side with new fields available for matching and logging such as certificate validity dates. On file matching and logging, it is now possible to use SHA1/SHA256 in addition to the obsolete MD5.
On the performance side, Suricata 3.2 run as fast as a Cheetah with the addition of the bypass mechanism that can help to fix the challenging Elephant flows. Another big improvement comes from the pre-filter system that allows packet inspecting keywords to be much faster.
Documentation has received a huge overhaul, with PDF and other formats now available.
On usability side, one can note that incompatible NIC offloading is now switched off by default. Also, the unix command socket is now enabled by default.
