Detect Network Intrusions with Snort and BASE

Snort is an open source packet sniffer and logger that can be used as a lightweight Intrusion Detection System (IDS) to detect a variety of attacks and probes such as buffer overflows, stealth port scans, CGI attacks, and more. The Basic Analysis and Security Engine (BASE) displays and reports intrusions and attacks logged in the Snort database in a web browser for convenient analysis.
