Ensure re-authentication for privilege escalation is not disabled globally

HochStufe 1Automatisiertfreebsd

Beschreibung

The operating system must be configured so that users must re-authenticate for privilege escalation. Without re-authentication, users may access resources or perform tasks for which they do not have authorization. When operating systems provide the capability to escalate a functional capability, it is critical the user re-authenticate. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

c=$(cat /usr/local/etc/sudoers /usr/local/etc/sudoers.d/* 2>/dev/null); [ -n "$c" ] || exit 1; printf '%s\n' "$c" | grep -E "^[^#].*!authenticate" | head -n 5 | grep . || echo compliant

Erwartete Ausgabe: compliant

So wird behoben
