Assessment Title

Rule Text

The /etc/news/passwd.nntp file must not have an extended ACL.

Description

Discussion Text

Extended ACLs may provide excessive permissions on the /etc/news/passwd.nntp file, which may permit unauthorized access or modification to the NNTP configuration.

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

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:mil.disa.fso.rhel11:def:553 compliant shell script
FILE_PATH="/etc/news/passwd.nntp"
if [ -f "$FILE_PATH" ]; then
   ACL_OUTPUT=$(stat -c '%A' "$FILE_PATH")
   if [[ "$ACL_OUTPUT" == *"acl"* ]]; then
      echo "FAIL"
      exit 1
   fi
fi
echo "PASS"
exit 0

Remediation

Remove the extended ACL from the file.
# setfacl --remove-all /etc/news/passwd.nntp
