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 configuration. . 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.
