TMA-ESXI9-3.12

Host must lock an account after a specified number of failed login attempts

SrednjaNivo 1Automatskavmware

Opis

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.

Kako se proverava

Metod provere: Komanda ljuske

shell
out=$(esxcli system settings advanced list -o /Security/AccountLockFailures 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk '$1=="Int" && $2=="Value:" {print $3; exit}')
case "$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
Očekivani izlaz
compliant

To set the maximum failed login attempts correctly, perform the following steps: 1. From the vSphere Web Client, select the host. 2. Click Configure then expand System. 3. Select Advanced System Settings then click Edit. 4. Enter Security.AccountLockFailures in the filter. 5. Set the value for this parameter to 5.
