The Port Scan Attack Detector (also known as psad) is an open source set of system daemons, which are designed to detect port scans and other suspect traffic.
The Port Scan Attack Detector project features a set of highly configurable danger thresholds (with sensible defaults), verbose alert messages, email alerting, DShield reporting, and automatic blocking of offending IP addresses.
