Assessment Title

Rule Text

All skeleton files (typically those in /etc/skel) must have mode 0644 or less permissive.

Description

Discussion Text

If the skeleton files are not protected, unauthorized personnel could change user startup parameters and possibly jeopardize user files.

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

Checks

DISA STIG (Manual Reference)

Check skeleton files permissions.
# ls -alL /etc/skel
If a skeleton file has a mode more permissive than 0644, this is a finding.

SCC Automation Reference

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.

#!/bin/bash
# Reconstructed from oval:mil.disa.fso.solaris11:def:120
# All skeleton files (typically those in /etc/skel) must have mode 0644 or less permissive.
# Per-module read mechanism curated from static teardown of DISA's SCC tool
# (SCAP Compliance Checker) -- see the SCC Automation Reference above.
#
# MANUAL REVIEW REQUIRED -- the module(s) below could not be reconstructed
# into working code from curated SCC reference data, and are excluded from
# the automated result:
#   - file_object (file_test) -- All skeleton files have mode 0644 or less permissive: no extractor for field "gexec"

echo "MANUAL REVIEW REQUIRED -- see notes above; no part of this check could be automated"

Remediation

Change the mode of skeleton files with incorrect mode.
# chmod 0644 <skeleton file>
