Diameter Security


Building a Secure Signaling Architecture

As service providers deploy IP-based LTE networks with a flatter and more open architecture, they are inherently more vulnerable to security threats that are increasing in both volume and diversity. The LTE evolved packet core (EPC) – as well as signaling and subscriber information – is not well-protected from attacks that come from outside the network access points. Equally troublesome is the rising trend of signaling storms that may occur due to operational issues or from malicious attacks.

Roaming agreements and third-party content providers complicate the situation by adding outside network connections. F5 offers a strategic approach to security with a consolidated Diameter signaling platform that optimizes the signaling network and protects against signaling security threats.

Why F5?

Superior Roaming Security

Ensure safe connections with other networks with a normalization engine that allows only supported AVPs and content to enter your network.

Network Masquerade

Get high security and failover protection by masquerading your network to prevent unauthorized access and ensure that external sessions are routing according to your set policies.

Overload Protection

Defend your network from overload and prevent the draining of network resources. Increase network security by hiding multi-node topology.
