Title

The SMS must be configured to remove or disable nonessential capabilities on SMS and TPS, which are not required for operation or not related to IDPS functionality. (Cat II impact)

Discussion

An IDPS can be capable of providing a wide variety of capabilities. Not all of these capabilities are necessary. Unnecessary services, functions, and applications increase the attack surface (sum of attack vectors) of a system. These unnecessary capabilities are often overlooked and therefore, may remain unsecured. Examples of unneeded services on TPS are web server, telnet, and TAXII.
