Lynis Security Controls

SCHD-7704 - Permissions of cron jobs


Lynis triggers this control when files have their file permissions set to a dangerous value. For example when everyone can write to them.



How to solve

Check the lynis.log and determine which files need to be changed. Normally it will be sufficient to give these file 0640 permissions.

Perform daily health checks of your environment, learn in-depth system hardening, and protect your systems better.
