PIF-Detector: An Accurate Low-Overhead Method for Detecting Persistent and Infrequent Flows
Persistent and infrequent (PI) flows refer to packet flows that last for a long time at low packet arrival rates in network traffic. It is crucial to accurately find these flows for uncovering stealthy network threats, such as advanced persistent threats (APTs) and low-rate denial-of-service attacks (LDoS). To this end...
