Assessment Title

Rule Text

A separate file system must be used for user home directories (such as /home or equivalent).

Description

Discussion Text

The use of separate file systems for different paths can protect the system from failures resulting from a file system becoming full or failing.

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.solaris11:def:232
if [ ! -s /etc/vfstab ]; then echo "PASS"; exit 0; fi
if grep -q "^[^#]*[ \t]/export/home[ \t]" /etc/vfstab; then echo "PASS"; exit 0; fi
if [ ! -d /export/zfs ]; then echo "PASS"; exit 0; fi
echo "FAIL"
exit 1

Remediation

Migrate the /export/home path onto a separate file system.
