Assessment Title

Rule Text

The rlogind service must not be running.

Description

Discussion Text

The rlogin service uses unencrypted network communications, which means that data from the login session, including passwords and all other information transmitted during the session, can be stolen by eavesdroppers on the network.

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

Checks

DISA STIG (Manual Reference)

 
To check that the "rlogin" service is disabled in system boot configuration, run the following command:

# chkconfig "rlogin" --list

Output should indicate the "rlogin" service has either not been installed, or has been disabled, as shown in the example below:

# chkconfig "rlogin" --list
rlogin off
OR
error reading information on service rlogin: No such file or directory


If the service is running, 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.fso.redhat.rhel6:def:1179

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

if rpm -qa | grep -q "rsh-server"; then
    echo "FAIL"
    exit 1
fi

if [ ! -f "/etc/xinetd.d/rlogin" ]; then
    echo "PASS"
    exit 0
fi

if grep -q "^\\s*disable\\s+=\\s+yes\\s*$" /etc/xinetd.d/rlogin; then
    echo "PASS"
    exit 0
fi

echo "FAIL"
exit 1

Remediation

The "rlogin" service, which is available with the "rsh-server" package and runs as a service through xinetd, should be disabled. The "rlogin" service can be disabled with the following command: 

# chkconfig rlogin off
