Assessment Title

Rule Text

The system must not allow autologin capabilities from the GNOME desktop.

Description

Discussion Text

As automatic logins are a known security risk for other than "kiosk" types of systems, GNOME automatic login should be disabled in pam.conf.

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.

#!/bin/sh
# OVAL Definition: oval:mil.disa.stig.solaris11:def:74

FILE="/etc/pam.d/gdm-autologin"

if [ ! -f "$FILE" ]; then
  echo "PASS"
  exit 0
fi

if grep -q ".*(auth|account).*" "$FILE" && ! grep -q "^[^#].*" "$FILE"; then
  echo "FAIL"
  exit 1
fi

echo "PASS"
exit 0

Remediation

The root role is required.

Modify the /etc/pam.d/gdm-autologin file.

# pfedit /etc/pam.d/gdm-autologin

Locate the lines:

auth required pam_unix_cred.so.1
auth sufficient pam_allow.so.1
account sufficient pam_allow.so.1

Change the lines to read:

#auth required pam_unix_cred.so.1
#auth sufficient pam_allow.so.1
#account sufficient pam_allow.so.1
