Hybrid attack is a combination of the above-mentioned attack types, and detects and selects the best attack method during the attack process. Hybrid attacks are often accompanied by these two types of attacks: resource consumption and service consumption.{}见虞姬走进来，虞子期有些无奈地起身离开，来到门口Groups objects into a tree structure to represent a "part-to-whole" hierarchy. Composite allows users to use both individual and composite objects consistently.When the server provides some UDP-based services, such as DNS, SMTP, NTP, etc., and finds some requests, in which the Response message is larger than the Request message, the Attacker sends a Request message that forges the source IP, and the source IP forges the IP address of the victim. After receiving the Request message, the server replies the "enlarged" Response message to the victim, thus realizing the amplification of traffic. The principle is roughly as follows:当两人迎面走去，站在一旁的人分明感受到一股强烈的气流扑面而来，不约而同被迫后退一步。《三个女人的秘密》讲述的是非常有钱的男人王大川在一个雨天遭遇车祸身亡，留下了一大笔钱财，可王大川膝下无儿无女，其前妻、老父亲都已不在人世，于是，在处理财产继承权的过程中，年轻貌美的女人冷静、摩登女人陆小曼、自称王大川妹妹的王丁粉墨登场。Another end-host-based solution is to shorten the time between a TCB entering the SYN-RECEIVED state and being recycled because it does not enter the next state. However, an obvious disadvantage of this scheme is that the attack can take advantage of ACK-SYN lost packets due to congestion or ACK packets completed by handshake, so that legally connected TCB will be recycled because the host is busy retransmitting these packets (because SYN-RECEIVED time is reduced). In addition, there is only a linear relationship between how much time the administrator reduces the SYN-RECEIVED state and the attacker's contract awarding rate. For the above reasons, this scheme is not recommended.
