Host must configure the password history setting to restrict the reuse of passwords

MediaNivel 1Automatizadavmware

Descripción

The goal is to inhibit the reuse of past passwords, acting as a deterrent against potential security breaches stemming from the exploitation of old, compromised credentials. This is achieved by configuring the Security.PasswordHistory parameter, which specifies the number of unique passwords a user must cycle through before a previous password can be reused. The audit reads Security.PasswordHistory with esxcli and requires 5. Runs in the ESXi Shell (busybox sh) as root.

Cómo se verifica

Método de auditoría: Comando de shell

shell

out=$(esxcli system settings advanced list -o /Security/PasswordHistory 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk '$1=="Int" && $2=="Value:" {print $3; exit}')
case "$v" in ''|*[!0-9-]*) echo '/Security/PasswordHistory: no integer value'; exit 1 ;; esac
if [ "$v" -eq 5 ]; then echo compliant; else echo "/Security/PasswordHistory = $v (expected 5)"; fi

Salida esperada: compliant
