Discussion

A mechanism to detect and prevent unauthorized communication flow must be configured or provided as part of the system design. If information flow is not enforced based on approved authorizations, the system may become compromised. Information flow control regulates where information is allowed to travel within a system and between interconnected systems. The flow of all application information must be monitored and controlled so it does not introduce any unacceptable risk to the systems or data. Application-specific examples of enforcement occur in systems that employ rule sets or establish configuration settings that restrict information system services, or provide a message filtering capability based on message content (e.g., implementing key word searches or using document characteristics). Applications providing information flow control must be able to enforce approved authorizations for controlling the flow of information between interconnected systems in accordance with applicable policy. This requirement pertains to Zero Trust.

Review the application documentation and deployed configuration to determine whether the application enforces approved authorizations for controlling the flow of information between interconnected systems based on organization-defined information flow control policies.

If the application does not enforce approved authorizations for controlling the flow of information between interconnected systems based on organization-defined information flow control policies, this is a finding.
