Assessment Title

Rule Text

All local initialization files must have mode 0740 or less permissive.

Description

Discussion Text

Local initialization files are used to configure the user's shell environment upon login. Malicious modification of these files could compromise accounts upon logon.

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

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.

export HOME=$(getent passwd "$USER" | cut -d: -f6)
if [ ! -d "$HOME" ]; then echo "FAIL"; exit 1; fi
for file in "$HOME"/.*; do
    if [ ! -f "$file" ]; then continue; fi
    perm=$(stat -c "%a" "$file")
    if [ "$perm" -gt 740 ]; then echo "FAIL"; exit 1; fi
done
echo "PASS"; exit 0

Remediation

Ensure user startup files have permissions of 0740 or more restrictive. Examine each user's home directory and verify all file names beginning with "." have access permissions of 0740 or more restrictive. If they do not, use the chmod command to correct the vulnerability. 

Procedure: 
# chmod 0740 .filename 

NOTE: The period is part of the file name and is required.
