The HYCU virtual appliance must enforce approved authorizations for controlling the flow of management information within the appliance based on information flow control policies.
An XCCDF Rule
Description
A mechanism to detect and prevent unauthorized communication flow must be configured or provided as part of the system design. If management information flow is not enforced based on approved authorizations, the network device may become compromised. Information flow control regulates where management information is allowed to travel within a network device. The flow of all management information must be monitored and controlled so it does not introduce any unacceptable risk to the network device or data.
