Ensure users must provide password for escalation

HighLevel 2Automatedfreebsd

Description

The operating system must be configured so that users must provide a password 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.

How it is checked

Audit method: Shell command

shell

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

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Based on the outcome of the audit procedure, use visudo -f <PATH TO FILE> to edit the relevant sudoers file. Remove any line with occurrences of NOPASSWD tags in the file.
