Samhain - host-based intrusion detection system
Anonymous Reader writes "Samhain is an open source file integrity and host-based intrusion detection system. It can run as a daemon process, and and thus can remember file changes - contrary to a tool that runs from cron, if a file is modified you will get only one report, while subsequent checks of that file will ignore the modification as it is already reported (unless the file is modified again)."
