1.3 Immunizing cron Jobs

To find programs that are run by cron, inspect your local cron configuration. Unfortunately, cron configuration is rather complex, so there are numerous files to inspect. Periodic cron jobs are run from these files:

/etc/crontab 
/etc/cron.d/* 
/etc/cron.daily/* 
/etc/cron.hourly/*
/etc/cron.monthly/* 
/etc/cron.weekly/*

For root's cron jobs, edit the tasks with crontab -e and list root's cron tasks with crontab -l. You must be root for these to work.

Once you find these programs, you can use the Add Profile Wizard to create profiles for them. Refer to Section 3.1, Adding a Profile Using the Wizard.
