Hardening My Cron Scripts, So Only Root Can Read Them


Hardening my cron scripts, so only root can read them.

To fix the permissions for the scripts that are responsible for executing scheduled job on our server so only "Root - SuperUser" can read it.

If not they are readable to ordinary users, just so you know.

Hardening my cron scripts, so only root can read them.

So open a terminal window and type:


Press enter and enter the root password.

Next type:

chmod 0700 /etc/cron.daily/*

Press Enter.

Do exactly the same if it is hourly, weekly or monthly !

The command is the same, just cron.daily you will change to cron.hourly, cron.minutes etc.
