What it checks
sshd MaxAuthTries value.
Why it matters
Allowing many tries favors brute force.
How to fix
Limit MaxAuthTries to 3–4.
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.
