The easiest way is to uninstall it!

How you do this depends on which distro you use.

Easy, only list the users that should be able to have crontabs in /etc/cron.allow. If that file exists and has one or more names in it any users not listed in the file will not be allowed to create crontab files. For more information see "man crontab".

Hi,

    Another way not very elegant but ...   If you don' run the crond daemon, nothing will happen.

Hope this help.

Bye

or you could move /usr/bin/crontab to crontab.old

The problem with removing crond or otherwise inactivating it is that you break other things, like log file rolling and other cleanup activities. The preferred solution is simply to restrict access. That's why there are cron.allow and cron.deny files.
