What it checks
sshd PasswordAuthentication (key-based preferred).
Why it matters
Password auth is a brute-force / credential-stuffing surface.
How to fix
Move to public-key auth, then PasswordAuthentication no.
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.
