Suricata is a threat detection engine.
By combining intrusion detection (IDS), intrusion prevention (IPS), network security monitoring (NSM) and PCAP processing, Suricata can quickly identify, stop, and assess even the most sophisticated attacks.
This is free and open source software.
Features include:
- IDS/IPS – implements a complete signature language to match on known threats, policy violations and malicious behaviour. Suricata will also detect many anomalies in the traffic it inspects. Suricata is capable of using the specialized Emerging Threats Suricata ruleset and the VRT ruleset.
- NSM – HTTP requests, log and store TLS certificates, extract files from flows and store them to disk. The full pcap capture support allows easy analysis.
- High performance – a single Suricata instance is capable of inspecting multi-gigabit traffic. The engine is built around a multi threaded, modern, clean and highly scalable code base.
- Automatic Protocol Detection – automatically detect protocols such as HTTP on any port and apply the proper detection and logging logic. This greatly helps with finding malware and CnC channels.
- Lua scripting.
