The transition to 5G infrastructure will likely increase the risk of a new series of Distributed Denial-of-Service (DDoS) attacks. While DDoS attacks range from targeted acts of retaliation, protest, theft, or extortion to pranksters, they all have one objective: disrupt service availability and reduce the ability of a business to function. Service providers building 5G infrastructure must implement a strategy to help mitigate the impact of attacks on bandwidth and subscribers. The move to using more virtualized technology can enable service providers to reduce the force and effectiveness of DDoS attacks more quickly and at scale.
For example, the F5 BIG-IP Advanced Firewall Manager Smart Virtual Edition (AFMVE)—integrated with an Intel® FPGA Programmable Acceleration Card (PAC) N3000—offers such an opportunity. By combining this solution with virtualized 5G infrastructure using commercial off-the-shelf (COTS) servers, service provider networks can automatically detect and better protect themselves faster than current methods against evolving, volumetric DDoS attacks that can negatively affect subscriber and user access to applications and other services.
The Intel FPGA PAC N3000 is dynamically configurable to accelerate multiple workloads such as 5G vRAN, Open vSwitch, Segment Routing v6, Tungsten Fabric, 5G User Plane Function (UPF), vBNG, and security solutions. This allows service providers to deploy a server plus the Intel FPGA PAC N3000 to support many cloud-native network functions or virtual appliances based on services demand at the edge. In testing performed by F5, the BIG-IP AFM Virtual Edition (VE) integrated with an Intel® FPGA PAC N3000, withstood a 70x higher level DDoS attack (TCP RST flood attack) than processing in software in a COTS server. The solution detected and blocked the “bad” attack traffic while letting in “good” traffic.1
In addition to service providers, enterprise organizations undergoing digital transformation will need to respond to these new types of DDoS attacks.
