Implementation of an Attack Detection System Based on Flow Features Using SmartNICs

Abstract (in Japanese) (See Japanese page) 
(in English) Detecting slow attacks, which disrupt services with mice flows, requires accurate tracking of both per-flow and cross-flow features, such as flow duration and per-source flow count. To address this in high-speed networks, we design an attack detection platform where a programmable switch filters known threats at high speed and a SmartNIC analyzes unknown threats by tracking these features. This paper designs, implements and evaluates a SmartNIC subsystem. Built on an NVIDIA BlueField-3 NIC, the system is optimized through (1) a multi-core architecture that eliminates shared access by partitioning per- and cross-flow features across cores, (2) a hash table that reduces memory accesses via contiguous memory placement, and (3) a lightweight packet dispatching mechanism leveraging NIC hardware features. Experimental results show that the system can process traffic at 15 million packets per second without packet loss.
