Ensure user guest is secured

MittelStufe 1Automatisiertaix

Beschreibung

This change locks and disables login access for the guest user account. This change disables direct local and remote login to the guest user account. Do not set a password on this account to ensure that the only access is via su from the root account. There should not be a requirement to log in as the guest user directly. Audit: `lsuser -a account_locked login rlogin guest` must show true/false/false; an absent account is compliant.

So wird geprüft

Prüfmethode: Shell-Befehl

shell

command -v lsuser >/dev/null 2>&1 || exit 1; lsuser guest >/dev/null 2>&1 || { echo compliant; exit 0; }; out=$(lsuser -a account_locked login rlogin guest 2>/dev/null); [ "$out" = "guest account_locked=true login=false rlogin=false" ] && echo compliant || echo "$out"

Erwartete Ausgabe: compliant

So wird behoben
