Construction of DDoS attacks malicious behavior knowledge base construction by Feiyang LIU, Kun LI, Fei SONG, Huachun ZHOU

“…Aiming at the problem of insufficient research on the knowledge base of distributed denial of service (DDoS) network attacks, a method for constructing a knowledge base of DDoS attacks malicious behavior was proposed.The knowledge base was constructed based on the knowledge graph, and contains two parts: a malicious traffic detection database and a network security knowledge base.The malicious traffic detection database detects and classifies malicious traffic caused by DDoS attacks, the network security knowledge base detects DDoS attacks from traffic characteristics and attack frameworks model malicious behaviors, and perform inference, tracing and feedback on malicious behaviors.On this basis, a distributed knowledge base was built based on the DDoS open threat signaling (DOTS) protocol to realize the functions of data transmission between distributed nodes, DDoS attack defense, and malicious traffic mitigation.The experimental results show that the DDoS attack malicious behavior knowledge base can effectively detect and mitigate the malicious traffic caused by DDoS attacks at multiple gateways, and has the knowledge update and reasoning function between the distributed knowledge bases, showing good scalability.…”
