-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2010-18177 2010-11-26 00:21:25 --------------------------------------------------------------------------------
Name : psad Product : Fedora 14 Version : 2.1.7 Release : 1.fc14 URL : http://www.cipherdyne.org/psad/ Summary : Port Scan Attack Detector (psad) watches for suspect traffic 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 (http://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 (http://www.cipherdyne.org/fwsnort/), which makes use of the iptables string match module to detect application layer signatures. -------------------------------------------------------------------------------- ChangeLog: * Thu Nov 25 2010 Peter Vrabec <[email protected]> 2.1.7-1 - upgrade * Tue Aug 11 2009 Ville Skyttä <[email protected]> - 2.1.3-4 - Use bzipped upstream tarball. -------------------------------------------------------------------------------- References: [ 1 ] Bug #609756 - SELinux is preventing /usr/bin/perl "write" access on psad. https://bugzilla.redhat.com/show_bug.cgi?id=609756 [ 2 ] Bug #583538 - psad has a few issues - I attached a selinux policy which may help https://bugzilla.redhat.com/show_bug.cgi?id=583538 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
