AOS must be configured to disable nonessential capabilities.
An XCCDF Rule
Description
It is detrimental for network elements to provide, or enable by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors. Network elements are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions and functions).
