Assessment Title

Rule Text

A File Transfer Protocol (FTP) server package must not be installed unless mission essential on RHEL 8.

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.

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.rhel8os:def:230558

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

installed_ftp_packages=$(rpm -qa | grep -E '.*ftpd.*' | wc -l)
if [ $installed_ftp_packages -gt 0 ]; then
  echo "FAIL"
  exit 1
fi

echo "PASS"
exit 0

Remediation

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

$ sudo yum remove vsftpd
