AIDE File Integrity Checker
ToolAIDE (Advanced Intrusion Detection Environment) takes a fingerprint of the files and directories you care about, then tells you exactly what changed since. It hashes contents with several digest algorithms and watches file attributes too, so a swapped binary or a quietly loosened config shows up in the next check instead of the next incident. Free under the GPL and actively maintained, it is the modern stand-in for Tripwire on Linux servers.
