Data integrity and host intrusion alert system

Samhain is an integrity checker and host intrusion detection system that can be used on single hosts as well as large, UNIX-based networks. It supports central monitoring as well as powerful (and new) stealth features to run undetected on memory using steganography. Main features * Complete integrity check + uses cryptographic checksums of files to detect modifications, + can find rogue SUID executables anywhere on disk, and * Centralized monitoring + native support for logging to a central server via encrypted and authenticated connections * Tamper resistance + database and configuration files can be signed + logfile entries and e-mail reports are signed + support for stealth operation
