    You have 4 different intent tools listed..

    AIDE is indeed a host ids...I have tested it, but not had the chance to
    really deploy it. AIDE looks at all aspects of the system,: file space
    (user induced DOS), password files, etc.

    Snort is a NETWORK IDS, not really a host IDS. Snort only alerts/captures
    based on network traffic.

    Tripwire is used to make sure critical files have not changed via checksum
    processes. This tool knows nothing of
    network intrusions, etc.

    Chkrootkit is a tool used to scan a system fro KNOWN traces of root kits.

    In truth, you need to deploy ALL of them for a nearly true secure
