Snort is a network intrusion detection system that performs real-time traffic analysis and packet logging on IP networks. It can perform protocol analysis, content searching/matching and can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and more. Snort has three primary uses: as a straight packet sniffer like tcpdump(1), as a packet logger (useful for network traffic debugging, etc), or as a full blown network intrusion detection system. Snort logs packets in either tcpdump(1) binary format or in Snort's decoded ASCII format to logging directories that are named based on the IP address of the "foreign" host. It should work any place libpcap does. Snort uses a flexible rules language to describe traffic that it should collect or pass, as well as a detection engine that utilizes a modular plugin architecture. It also has real-time alerting capabilities.
