The technology includes a method performed by a security system of a 5G network. The security system is instantiated to sort incoming or outgoing network traffic at a perimeter of the 5G network into one of multiple groups that are each uniquely associated with one of multiple functions or applications and one of multiple security levels. The system can inspect portions of incoming network traffic that contain addressing information required for the network traffic to reach an intended application or function, sorting the incoming network traffic into the groups based in part on the inspection of the portions of the network traffic, and dynamically directing the network traffic for the 5G network based on a particular security level associated with a particular application or a particular function of each of the groups.
