Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-268225	HYCU-ND-000070	SV-268225r1038375_rule		Medium

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. Satisfies: SRG-APP-000038-NDM-000213, SRG-APP-000880-NDM-000290
