Mobileum 5G Signaling Firewall (SEPP)
The development of mobile networks to 5G requires mobile operators to change the way in which the network elements can communicate with each other and between 5G networks. The 5G network uses a completely new signaling protocol, HTTP/2, compared to the old signaling protocols of the previous generation mobile networks. Therefore, the security for signaling of 5G networks is gradually becoming urgent in the context of infrastructure deployment is approaching.
Mobileum offer a solution for 5G signaling security named Security Edge Protection Proxy (SEPP) which protects the home network and acts as a security gateway. Located at the edge of the network, it polices connections between the home network and the visited networks. Mobileum’s SEPP offers end-to-end 5G Security as a standards-based node based upon 3gpp specifications. This is a significant enhancement to security, compared to the prevailing practices in 4G/3G/2G networks in which SS7 and Diameter were used.
The main advantages of Mobileum 5G Signaling Firewall
The Mobileum SEPP enables secure interconnection between 5G networks ensuring end-to-end confidentiality and integrity between source and destination network for all 5G interconnect roaming messages. Mobileum’s SEPP provides the following features to CSPs:
- Security at the application level and protection against eavesdropping and replay attacks.
- End-to-end authentication, integrity, and confidentiality protection through signature and encryption of all HTTP2/ roaming messages.
- Key management mechanisms for configuring the required cryptographic keys and performing procedures to negotiate security capacity.
- Message filtering and monitoring, topology hiding, and JSON object validation; including cross-layer information verification with address information on the IP layer.
