The OL 8 lastlog command must be owned by root.

Description

Discussion Text

Unauthorized disclosure of the contents of the /var/log/lastlog file can reveal system data to attackers, thus compromising its confidentiality.

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.

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.ol8os:def:248706
if [ ! -f "/usr/bin/lastlog" ]; then echo "PASS"; exit 0; fi
if [ $(stat -c "%U /usr/bin/lastlog" | awk '{print $2}') != "root" ]; then echo "FAIL"; exit 1; fi
echo "PASS"; exit 0

Remediation

Configure the "lastlog" command for OL 8 to be owned by root with the following command:   

$ sudo chown root /usr/bin/lastlog
