Port Scan Attack Detector 2.0.8 (Default branch) |
|
|
The Port Scan Attack Detector (psad) is a
collection of three system daemons that are
designed to work with the Linux iptables
firewalling code to detect port scans and other
suspect traffic. It 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. Psad incorporates many of
the packet signatures included in Snort to detect
various kinds of suspicious scans, and implements
the same passive OS fingerprinting algorithm used
by p0f.

Changes:
A --gnuplot mode was added so that psad can output data that is suitable for plotting with gnuplot. The ability to negate match conditions on fields specified with the --CSV-fields argument was added. The Storable-2.16 module was added along with the --use-store-file argument so that in --gnuplot mode the Gnuplot data can be stored on disk and retrieved quickly. --analysis-fields was added so the iptables log messages that are parsed in -A mode can be restricted to those that meet certain criteria.
