Snort

Snort is an open source network intrusion prevention system (IPS) capable of performing 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 uses a flexible rules language to describe traffic that it should collect or pass, as well as a detection engine that uses a modular plug-in architecture. Snort has a real-time alerting capability as well, incorporating alerting mechanisms for syslog, a user-specified file, a UNIX socket, or WinPopup messages to Windows clients using Samba’s smbclient. Snort has three primary uses. It can be used as a straight packet sniffer like tcpdump, a packet logger (useful for network traffic debugging and so), or as a full-blown network intrusion prevention system.
