Enable cron Service

An XCCDF Rule

Description

The crond service is used to execute commands at preconfigured times. It is required by almost all systems to perform necessary maintenance tasks, such as notifying root of system activity. The crond service can be enabled with the following command:

$ sudo systemctl enable crond.service

Rationale

Due to its usage for maintenance and security-supporting tasks, enabling the cron daemon is essential.
