Ensure access to /etc/cron.daily is configured
MediumLevel 1Automatedlinux
Description
The /etc/cron.daily directory contains system cron jobs that need to run on a daily 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.daily/ 2>&1) || { echo "step1: $s"; return 1; }; set -- $s; m=$((8#$1)); [ $((m & ~0700)) -eq 0 ] && [ "$2" = 0 ] && [ "$3" = 0 ] || { echo "step1: /etc/cron.daily/ 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.daily directory: # chown root:root /etc/cron.daily/ # chmod og-rwx /etc/cron.daily/
