Assessment Title

Rule Text

TOSS must not have the rsh-server package installed.

Description

Discussion Text

Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised. The rsh-server service provides an unencrypted remote access service that does not provide for the confidentiality and integrity of user passwords or the remote session and has very weak authentication. Satisfies: SRG-OS-000074-GPOS-00042, SRG-OS-000095-GPOS-00049

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

if [ ! -z "$(rpm -qa | grep -w rsh-server)" ]; then echo "FAIL"; exit 1; fi; echo "PASS"; exit 0

Remediation

Configure the operating system to disable nonessential capabilities by removing the rsh-server package from the system with the following command:

$ sudo yum remove rsh-server
