MediumLevel 1Automatedlinux

Description

Squid is a standard proxy server used in many distributions and environments.

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=$(bash -c 'rpm -q squid' 2>&1); printf '%s\n' "$o" | tr -s ' \t' '  ' | sed 's/^ //;s/ $//' | grep -Fxq -- 'package squid is not installed' || { echo step1: missing 'package squid is not installed'; return 1; }; }; alt1() { command -v grep >/dev/null 2>&1 || { echo "step1: grep not installed"; return 1; }; command -v systemctl >/dev/null 2>&1 || { echo "step1: systemctl not installed"; return 1; }; o=$(bash -c 'systemctl is-enabled squid.service 2>/dev/null | grep '"'"'enabled'"'"'' 2>/dev/null); [ -z "$o" ] || { echo "step1: $o" | head -c 300; return 1; }; command -v grep >/dev/null 2>&1 || { echo "step2: grep not installed"; return 1; }; command -v systemctl >/dev/null 2>&1 || { echo "step2: systemctl not installed"; return 1; }; o=$(bash -c 'systemctl is-active squid.service 2>/dev/null | grep '"'"'^active'"'"'' 2>/dev/null); [ -z "$o" ] || { echo "step2: $o" | head -c 300; return 1; }; }; if alt0 || alt1; then echo compliant; fi
Expected output
compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following commands to stop squid.service and remove the squid package: # systemctl stop squid.service # dnf remove squid - OR - If the squid package is required as a dependency: Run the following commands to stop and mask the squid.service: # systemctl stop squid.service # systemctl mask squid.service
