Ensure permissions on /etc/cron.hourly are configured

MediumLevel 1Automatedlinux

Description

This directory contains system cron jobs that need to run on an hourly basis. The files in this directory cannot be manipulated by the crontab command, but are instead edited by system administrators using a text editor. The commands below restrict read/write and search access to user and group root, preventing regular users from accessing this directory.

How it is checked

Audit method: Shell command

shell

alt0() { command -v stat >/dev/null 2>&1 || { echo "step1: stat not installed"; return 1; }; o=$(bash -c 'stat /etc/cron.hourly' 2>&1); printf '%s\n' "$o" | tr -s ' \t' '  ' | sed 's/^ //;s/ $//' | grep -Fxq -- 'Access: (0600/drwx------) Uid: ( 0/ root) Gid: ( 0/ root)' || { echo step1: missing 'Access: (0600/drwx------) Uid: ( 0/ root) Gid: ( 0/ root)'; return 1; }; }; if alt0; then echo compliant; fi

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following commands to set ownership and permissions on /etc/cron.hourly : # chown root:root /etc/cron.hourly # chmod 600 /etc/cron.hourly
