Assessment Title

Rule Text

The operating system must terminate all sessions and network connections when nonlocal maintenance is completed.

Description

Discussion Text

Nonlocal maintenance and diagnostic activities are those activities conducted by individuals communicating through a network, either an external network (e.g., the internet) or an internal network. The operating system needs to ensure all sessions and network connections are terminated when nonlocal maintenance is completed.

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.

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:69
if [ ! -f "/etc/ssh/sshd_config" ]; then echo "PASS"; exit 0; fi
grep -q "^\\s*[Cc][Ll][Ii][Ee][Nn][Tt][Aa][Ll][Ii][Vv][Ee][Ii][Nn][Tt][Ee][Rr][Vv][Aa][Ll]\\s+600" /etc/ssh/sshd_config && grep -q "^\\s*[Cc][Ll][Ii][Ee][Nn][Tt][Aa][Ll][Ii][Vv][Ee][Cc][Oo][Uu][Nn][Tt][Mm][Aa][Xx]\\s+0" /etc/ssh/sshd_config && echo "PASS" || echo "FAIL"; exit 0

Remediation

The root role is required.

Configure the system to disconnect SSH sessions after 10 minutes of inactivity.

# pfedit /etc/ssh/sshd_config

Insert the two lines:

ClientAliveInterval 600
ClientAliveCountMax 0

Restart the SSH service with the new configuration.

# svcadm restart svc:/network/ssh
