I would like to announce this information, in case anyone would be interested in this research. The IDS system is designed as a kernel module for FreeBSD 5.2. It is inspired by the SpamAssassin program, which detects spam by applying a set of tests to every email message and counting a sum of point score generated by each test. My IDS system applies a set of tests to every running process in the OS and counts its score generated by the tests. Therefore, the purpose of the IDS is not to monitor the network traffic, but rather to monitor the process activity. The current system status is a "working prototype" - it is not ready for production usage, but it may serve as a good base for an interesting research. If you are interested in this topic, please read the details here: http://plusik.pohoda.cz/thesis/ Thanks, Tomas
