The /etc/netsvc.conf file must be root owned.

Description

Discussion Text

The /etc/netsvc.conf file is used to specify the ordering of name resolution for the sendmail command, alias resolution for the sendmail command, and host name resolution routines. Malicious changes could prevent the system from functioning correctly or compromise system security.

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:8
if [ ! -f "/etc/netsvc.conf" ]; then echo "PASS"; exit 0; fi; uid=$(stat -c "%u" /etc/netsvc.conf); if [ $uid -eq 0 ]; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Change the owner of the /etc/netsvc.conf file to root. 

# chown root /etc/netsvc.conf
