Assessment Title

Rule Text

All Network File System (NFS) shared system files and system directories must be group-owned by root, bin, sys, or other.

Description

Discussion Text

Failure to give group-ownership of sensitive files or directories to root provides the members of the owning group with the potential to access sensitive information or change system configuration which could weaken the system's security posture.

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.

A standalone Shell script to assess this control automatically. Review before running it in your environment.

for dir in $export_dir; do if [ ! -d "$dir" ]; then continue; fi; if [ $(stat -c "%G" "$dir") = "root" ] || [ $(stat -c "%G" "$dir") = "bin" ] || [ $(stat -c "%G" "$dir") = "sys" ]; then continue; else echo "FAIL"; exit 1; fi; done; echo "PASS"; exit 0;

Remediation

Change the group owner of the share directory.
# chgrp (root|bin|sys|other) <exported directory>
