The rise in cyberthreats and fraud across mobile networks calls for advanced security solutions capable of securing traffic flows and safeguarding critical data, applications and network assets. Expanded network ecosystems pave the way for new attack vectors and threats become increasingly evasive. Considering potential risks to the 5G and LTE network security means not only focusing on vulnerable IoT devices and insider threats. Among the 5G security threats and issues with the potential to impact data and traffic flow are also Distributed Denial of Service (DDoS) attacks, man-in-the-middle attacks and supply chain attacks. Not only are the latter ones the most notorious attacks, they can also quickly become extremely costly for a company and permanently damage its reputation.

Identifying and mitigating such threats in a timely and reliable manner presents a significant challenge for mobile operators because they lack subscriber or session awareness. To address these vulnerabilities and increase the resilience of mobile networks against future security threats, specifically across LTE and 5G, operators are implementing intelligent load balancing. This provides real-time subscriber awareness and session awareness for enhanced visibility of malicious, suspicious and anomalous traffic flows. This way, operators benefit from real-time network threat intelligence and can protect the network.
