Assessment Title

Rule Text

All local file systems must employ journaling or another mechanism ensuring file system consistency.

Description

Discussion Text

File system journaling, or logging, can allow reconstruction of file system data after a system crash preserving the integrity of data that may have otherwise been lost. Journaling file systems typically do not require consistency checks upon booting after a crash, which can improve system availability. Some file systems employ other mechanisms to ensure consistency also satisfying this requirement.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

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.fso.rhel11:def:253
if [ ! -f "/proc/mounts" ]; then echo "PASS"; exit 0; fi
for fs in rootfs jfs vxfs hfs xfs reiserfs ext3 ext4 iso9660 udf; do
    grep "/dev[^ ]* $fs "/proc/mounts &> /dev/null && break
done
if [ "$fs" != "" ]; then echo "PASS"; exit 0; fi
echo "FAIL"; exit 1

Remediation

Convert local file systems to use journaling or another mechanism ensuring file system consistency.
