Assessment Title
Rule Text
The Infoblox DNS service member implementation must enforce approved authorizations for controlling the flow of information between DNS service members and between DNS service members and DNS clients based on TSIG policies.
Description
Discussion Text
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 occurs 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 keyword 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.
Within the context of DNS, this is applicable in terms of controlling the flow of DNS information between systems, such as DNS zone transfers.
