Disable SMART Disk Monitoring Service (smartd)

An XCCDF Rule

Description

SMART (Self-Monitoring, Analysis, and Reporting Technology) is a feature of hard drives that allows them to detect symptoms of disk failure and relay an appropriate warning. The smartd service can be disabled with the following command: 
$ sudo systemctl mask --now smartd.service

Rationale

SMART can help ensure availability of systems by notifying system operators of failing hardware. Nevertheless, if it is not needed or the system's drives are not SMART-capable (such as solid state drives), this service can be disabled.
