Ensure access to /etc/cron.hourly is 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() { s=$(stat -Lc '%a %u %g' /etc/cron.hourly/ 2>&1) || { echo "step1: $s"; return 1; }; set -- $s; m=$((8#$1)); [ $((m & ~0700)) -eq 0 ] && [ "$2" = 0 ] && [ "$3" = 0 ] || { echo "step1: /etc/cron.hourly/ is mode $1 uid $2 gid $3, want 700 or stricter, uid 0, gid 0"; return 1; }; }; if alt0; then echo compliant; fi- Expected output
compliant
How it is fixed
Fix method: Guidance or infrastructure patch
- IF - cron is installed on the system: Run the following commands to set ownership and permissions on the /etc/cron.hourly directory: # chown root:root /etc/cron.hourly/ # chmod og-rwx /etc/cron.hourly/
