Assessment Title

Rule Text

RHEL 10 must use a separate file system for user home directories (such as "/home" or an equivalent).

Description

Discussion Text

Ensuring that "/home" is mounted on its own partition enables the setting of more restrictive mount options and helps ensure that users cannot trivially fill partitions used for log or audit data storage.

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

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:280937

if [ -d /home ] && [ $(stat -c "%F" /home) = "ext4" ] && [ $(df /home | awk 'NR==2{print $1}') != "/" ]; then
  echo "PASS"
  exit 0
else
  echo "FAIL"
  exit 1
fi

Remediation

Configure RHEL 10 to use a separate file system for user home directories by migrating the "/home" directory onto a separate file system/partition.
