Saint Jude LKM is a Linux Kernel Module for the 2.2.0 and 2.4.0 series of kernels. This module implements the Saint Jude model for improper privilege transitions. This will permit the discovery of local and remote root exploits during the exploit itself. Once discovered, Saint Jude will terminate the execution, preventing the root exploit from occurring. This is done without checking for attack signatures of known exploits, and thus should work for both known and unknown exploits.

Trafdisp is a sniffer which allows you to monitor the amount of incoming/outgoing KBps on a selected network interface(s) from at least one machine. It allows a network administrator to monitor the traffic that is generated by all the hosts on the network. The traffic is viewable in neat graphs that are generated by a PHP-enabled Web-server. The logs are stored in a MySQL table.
