HNSEC04-BP02 Implement routing controls for network segments
Implementing routing controls for network segments involves strategically managing traffic flow between different parts of your network infrastructure. This includes setting up route tables to direct traffic based on security policies. These controls should enforce the principle of least privilege, ensuring network components can only communicate with authorized segments.
Desired outcome: Enable centralized, flexible, and secure traffic routing between cloud and on-premises networks.
Level of risk exposed if this best practice is not established: High
Benefits of establishing this best practice:
-
Provides centralized control of network paths
-
Allows for segmentation and isolation using null routes
-
Prevents unauthorized or misrouted hybrid traffic
Implementation guidance
-
Design route tables to segment environments and block unnecessary paths.
-
Use null routes to block specific destinations when needed.
-
Periodically review and simulate route changes before deployment.
