Install the ntp service

An XCCDF Rule

Description

The ntpd service should be installed.

Rationale

Time synchronization (using NTP) is required by almost all network and administrative tasks (syslog, cryptographic based services (authentication, etc.), etc.). Ntpd is regulary maintained and updated, supporting security features such as RFC 5906.
