Description

Port Scan Attack Detector (psad) is a lightweight system daemon written in Perl designed to work with Linux iptables firewalling code to detect port scans and other suspect traffic. It features a set of 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, reverse DNS info, email and syslog alerting, automatic blocking of offending ip addresses via dynamic configuration of iptables rulesets, and passive operating system fingerprinting. In addition, psad incorporates many of the tcp, udp, and icmp signatures included in the snort intrusion detection system (https://www.snort.org) to detect highly suspect scans for various backdoor programs (e.g. EvilFTP, GirlFriend, SubSeven), DDoS tools (mstream, shaft), and advanced port scans (syn, fin, xmas) which are easily leveraged against a machine via nmap. psad can also alert on snort signatures that are logged via fwsnort (https://www.cipherdyne.org/fwsnort/), which makes use of the iptables string match module to detect application layer signatures.
