The other is resource depletion

essence of DDoS attacks we define is to consume a large amount of resources or occupy them for a long time to reject other user services. Flood attacks are used to quickly consume a large amount of resources and send a large amount of data and requests. Compared with flood attacks, slow

. Second, Distributed Denial of Service attacks are even more difficult to prevent. Because the Distributed Denial-of-Service attack data streams come from many sources and attack tools use the random IP technology, the similarity with valid access data streams is increased, making it more difficult to judge and prevent attacks. Attack policy and Prevention At present, with the wide spread of various
