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.fso.aix11:def:343
if [ ! -f "/var/private/smbpasswd" ]; then echo "PASS"; exit 0; fi; stat -c "%U %n" "/var/private/smbpasswd" | awk '{if ($1 == 0 && $2 == "/var/private/smbpasswd") print "PASS"; else print "FAIL" }'; exit 0

Remediation

Change the owner of the smbpasswd file to root.

# chown root /var/private/smbpasswd
