Assessment Title

Rule Text

Direct root account login must not be permitted for SSH access.

Description

Discussion Text

The system should not allow users to log in as the root user directly, as audited actions would be non-attributable to a specific user.

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

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:66

if ! grep -qE "^\\s*[Pp][Ee][Rr][Mm][Ii][Tt][Rr][Oo][Oo][Tt][Ll][Oo][Gg][Ii][Nn]\\s+" /etc/ssh/sshd_config && \
    grep -qE "^\\s*PermitRootLogin\\s+no$" /etc/ssh/sshd_config; then
    echo "FAIL"
    exit 1
else
    echo "PASS"
    exit 0
fi

Remediation

The root role is required.

Modify the sshd_config file

# pfedit /etc/ssh/sshd_config

Locate the line containing:

PermitRootLogin

Change it to:

PermitRootLogin no

Restart the SSH service.

# svcadm restart svc:/network/ssh
