%description
Port Scan Attack Detector (psad) is a collection of three lightweight
system daemons written in Perl and in C that are 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.
