What it checks
Warnings from rkhunter/chkrootkit when installed.
Why it matters
Dedicated scanners corroborate compromise indicators.
How to fix
Verify each warning (rule out false positives); isolate on real hits.
InfraGuard runs all 36 checks across your servers at once and grades each host A–F.
Track these versions on your own servers
InfraGuard collects installed software versions from every server and flags the ones with known vulnerabilities. Self-hosted — nothing leaves your network.
