Assessment Title

Rule Text

RHEL 10 must be configured so that cron configuration file directories are owned by root.

Description

Discussion Text

Service configuration files enable or disable features of their respective services, which if configured incorrectly could lead to insecure and vulnerable configurations. Therefore, service configuration files must be owned by the correct group to prevent unauthorized changes.

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

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.stig.rhel10os:def:281043
# RHEL 10 must be configured so that cron configuration file directories are owned by root.
# 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) -- /etc/cron* files owned by root: no extractor for field "user_id"

# /etc/cron* directories owned by root
# file_object (file_test)
test_2() {
  [ "$(stat -c '%u' '^/etc/cron.*$')" -eq 0 ]
}

if test_2; then
  echo "PASS (automated portion only -- MANUAL REVIEW still required, see notes above)"
else
  echo "FAIL (or see MANUAL REVIEW note above)"

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:281043
if [ ! -d "/etc" ]; then echo "PASS"; exit 0; fi
for dir in /etc/cron.*; do
    if [ -d "$dir" ]; then
        uid=$(stat -c "%u" "$dir")
        if [ "$uid" -ne 0 ]; then echo "FAIL"; exit 1; fi
    fi
done
for file in /etc/cron.*; do
    if [ ! -f "$file" ]; then continue; fi
    uid=$(stat -c "%u" "$file")
    if [ "$uid" -ne 0 ]; then echo "FAIL"; exit 1; fi
done
echo "PASS"; exit 0

Remediation

Configure RHEL 10 so that cron configuration file directories are owned by root with the following command:

$ sudo chown root [cron config file]
