Assessment Title

Rule Text

The Red Hat Enterprise Linux operating system must not have a File Transfer Protocol (FTP) server package installed unless needed.

Description

Discussion Text

The FTP service provides an unencrypted remote access that does not provide for the confidentiality and integrity of user passwords or the remote session. If a privileged user were to log on using this service, the privileged user password could be compromised. SSH or other encrypted file transfer methods must be used in place of this service.

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

Checks

DISA STIG (Manual Reference)

Verify an FTP server has not been installed on the system.

Check to see if an FTP server has been installed with the following commands:

# yum list installed vsftpd

 vsftpd-3.0.2.el7.x86_64.rpm

If "vsftpd" is installed and is not documented with the Information System Security Officer (ISSO) as an operational requirement, 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.stig.rhel7:def:1301
if rpm -q vsftpd > /dev/null 2>&1; then echo "FAIL"; exit 1; fi; echo "PASS"; exit 0

Remediation

Document the "vsftpd" package with the ISSO as an operational requirement or remove it from the system with the following command:

# yum remove vsftpd
