Ensure ftp client is not installed

MediumLevel 1Automatedlinux

Description

FTP (File Transfer Protocol) is a traditional and widely used standard tool for transferring files between a server and clients over a network, especially where no authentication is necessary (permits anonymous users to connect to a server).

How it is checked

Audit method: Shell command

shell

alt0() { command -v rpm >/dev/null 2>&1 || { echo "step1: rpm not installed"; return 1; }; o=$(bash -c 'rpm -q ftp' 2>&1); printf '%s\n' "$o" | tr -s ' \t' '  ' | sed 's/^ //;s/ $//' | grep -Fxq -- 'package ftp is not installed' || { echo step1: missing 'package ftp is not installed'; return 1; }; }; if alt0; then echo compliant; fi

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following command to remove ftp: # dnf remove ftp
