The ALG that is part of a CDS must apply information flow control to data transferred between security domains by means of a policy filter which consists of a set of hardware and/or software.

Description
Information flow control regulates where information is allowed to travel within a network and between interconnected networks. The flow of all network traffic must be monitored and controlled so it does not introduce any unacceptable risk to the network infrastructure or data. Apply information flow control to data transferred between security domains by means of a set of hardware and/or software, collectively known as the "filter". Flow control includes the inspection, sanitization, and/or rejection of data from one security domain prior to transfer of data to a different security domain. For an access type CDS, the remote desktop architecture provides the capability for a user to have access from a single device to computing platforms, applications, or data residing on multiple different security domains; while preventing any information flow between the different security domains. 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-204913r1137548_chk)

If the ALG is not used as part of a CDS, this is not applicable. Verify the ALG applies information flow control to data transferred between security domains by means of a policy filter which consists of a set of hardware and/or software. If the ALG is not configured to apply information flow control to data transferred between security domains by means of a policy filter which consists of a set of hardware and/or software, this is a finding.

Fix Text (F-5181r395873_fix)

If the ALG is used as part of a CDS, configure the ALG to apply information flow control to data transferred between security domains by means of a policy filter which consists of a set of hardware and/or software.
