Assessment Title

Rule Text

There must be no shosts.equiv files on the SUSE operating system.

Description

Discussion Text

The shosts.equiv files are used to configure host-based authentication for the system via SSH. Host-based authentication is not sufficient for preventing unauthorized access to the system, as it does not require interactive identification and authentication of a connection request, or for the use of two-factor authentication.

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

Checks

DISA STIG (Manual Reference)

Verify there are no "shosts.equiv" files on the SUSE operating system.

Check the system for the existence of these files with the following command:

# find /etc -name shosts.equiv

If any "shosts.equiv" files are found on the system, this is a finding.

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.sles12:def:132
if [ ! -e /shosts.equiv ]; then echo "PASS"; exit 0; fi; echo "FAIL"; exit 1

Remediation

Remove any "shosts.equiv" files found on the SUSE operating system.

# rm /[path]/[to]/[file]/shosts.equiv
