Assessment Title

Rule Text

RHEL 10 must ensure account lockouts persist.

Description

Discussion Text

Having lockouts persist across reboots ensures that an account is unlocked only by an administrator. If the lockouts did not persist across reboots, an attacker could reboot the system to continue brute force attacks against the accounts on the system. Satisfies: SRG-OS-000021-GPOS-00005, SRG-OS-000329-GPOS-00128

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

#!/bin/sh
# OVAL Definition: oval:mil.disa.stig.rhel10os:def:281198
if [ ! -f "/etc/security/faillock.conf" ]; then echo "PASS"; exit 0; fi
if grep -q "^\\s*dir\\s*=\\s*/var/log/faillock\\s*$" /etc/security/faillock.conf; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Configure RHEL 10 to maintain the contents of the "faillock" directory after a reboot.

Add/modify the "/etc/security/faillock.conf" file to match the following line:

dir = /var/log/faillock
