Port Scan Attack Detector
http://www.cipherdyne.com/
Port Scan Attack Detector (psad) works with the Linux kernel firewalling code (iptables in the 2.4.x kernels, and ipchains in the 2.2.x kernels) to detect port scans. It has highly configurable danger thresholds (with sensible defaults provided), verbose alert messages that include the source, destination, scanned port range, begin and end times, TCP flags and corresponding nmap options (Linux 2.4.x kernels only), email alerting, and automatic blocking of offending IP addresses via dynamic configuration of ipchains/iptables firewall rulesets. For the 2.4.x kernels psad incorporates many of the TCP signatures included in Snort to detect suspect scans for various backdoor programs (e.g. EvilFTP, GirlFriend, SubSeven), DDoS tools (mstream, shaft), and advanced port scans (syn, fin, Xmas) can be leveraged against a machine via nmap.
