Port Scan Attack Detector

PSAD is a collection of four lightweight system daemons (in Perl and C) designed to work with iptables to detect port scans. It features:

 * a set of highly configurable danger thresholds (with sensible
   defaults provided);
 * verbose alert messages that include the source, destination,
   scanned port range, beginning and end times, TCP flags, and
   corresponding Nmap options;
 * reverse DNS information;
 * alerts via email;
 * automatic blocking of offending IP addresses via dynamic firewall

When combined with fwsnort and the iptables string match extension, PSAD is capable of detecting many attacks described in the Snort rule set that involve application layer data.
