Description

Discussion Text

Without protection of the transmitted information, confidentiality and integrity may be compromised because unprotected communications can be intercepted and either read or altered. Satisfies: SRG-OS-000112-GPOS-00057, SRG-OS-000113-GPOS-00058, SRG-OS-000423-GPOS-00187, SRG-OS-000424-GPOS-00188, SRG-OS-000425-GPOS-00189, SRG-OS-000426-GPOS-00190

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.amzlx23os:def:274038

if ! command -v rpm &> /dev/null; then
  echo "FAIL"
  exit 1
fi

if rpm -qa | grep -q 'openssh-server'; then
  echo "PASS"
  exit 0
else
  echo "FAIL"
  exit 1
fi

Remediation

Configure Amazon Linux 2023 to have the openssh-server package installed with the following command:
 
$ sudo dnf install -y openssh-server
