The IPS must restrict or block harmful or suspicious communications traffic between interconnected networks based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.

Description
Restricting the communications traffic as it crosses external/perimeter boundaries, also known as information flow control, helps prevent malicious or suspicious access. The IPS must be configured to leverage policy filters, rules, signatures, and/or behavior analysis algorithms that inspects and restricts traffic based on the characteristics of the information and/or the information path. Inspection is based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic. DOD has defined the actions required upon the detection of harmful or suspicious traffic is to restrict, redirect, drop, or block the traffic. Specific actions taken depends on the site's security plan and the device's capabilities. This requirement also applies to Zero Trust initiatives.

Who does this work

18 NICE work roles and 10 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-206865r1137717_chk)

If the device being reviews is an IDS, this is not applicable. Verify the IPS enforces approved authorizations by restricting or blocking the flow of harmful or suspicious communications traffic for controlling the flow of information between interconnected networks. If the IPS does not enforce approved authorizations by restricting or blocking the flow of harmful or suspicious communications traffic for controlling the flow of information between interconnected networks, this is a finding.

Fix Text (F-7119r1137716_fix)

Configure the IPS to enforce approved authorizations by restricting or blocking the flow of harmful or suspicious communications traffic for controlling the flow of information between interconnected networks.
