Which type of firewall configuration should be deployed to protect north-south traffic?
To protect north-south traffic, it's best to use a high-throughput appliance deployed in high availability mode. North-south traffic refers to data traveling between an external network and an internal network, thus having high availability increases resiliency and ensures continuous protection against threats. High-throughput appliances are built to handle large volumes of traffic efficiently, making them ideal for the critical task of securing north-south traffic.
(pg. 59) North-south traffic is secured by one or more physical form factor perimeter edge firewalls. The edge firewall usually is a high-throughput appliance working in high availability active/passive (or active/active) mode to increase resiliency. It controls all the traffic reaching into the data center and authorizes only allowed and “clean” packets to flow into the virtualized environment.
