fupids (the fuzzy userprofile intrusion detection system) is a user-profile based IDS for the OpenBSD kernel. It modifies certain syscalls in order to detect suspicious behavior. For example, it watches for network devices being set to promiscuous mode, and it watches for the creation of listen() sockets by users. fupids also handles a program profile for your local users, and it can find attackers who overtake existing accounts.
