VMware ESXi
TMA-ESXI9-3.12
Host must lock an account after a specified number of failed login attempts
Descrição
The security control involves restricting account access following a specified number of failed login attempts, acting as a deterrent against brute-force attacks. This control is applicable for SSH and vSphere Web Services SDK access, though not for the Direct Console Interface (DCUI) and the ESXi Shell. The audit reads Security.AccountLockFailures with esxcli and requires 5. Runs in the ESXi Shell (busybox sh) as root.

case "$v" in ''|*[!0-9-]*) echo '/Security/AccountLockFailures: no integer value'; exit 1 ;; esac
if [ "$v" -eq 5 ]; then echo compliant; else echo "/Security/AccountLockFailures = $v (expected 5)"; fi- Saída esperada
