Therefore, if C wants to forge the packet from A to B, it should fill in the above-mentioned IP header and TCP header with the source IP, source port, target IP and target port. Here B is the server, IP and port are open, A is the target we want to attack, IP certainly knows, but the source port of A is not clear, because it may be randomly generated by A. Of course, if we can find out the rule of generating source port for common OS such as Windows and Linux, we can still do it. In addition, we can step on the connection port of Car A through a large number of controlled hosts.只要努力不懈梦想一定会实现──。现在只需要朝著那闪耀的目标，奋不顾身地勇往直前就行了！从此，少女们“ 大家一起实现的故事”（学园偶像计划）就此展开！艾丽·范宁将主演Hulu新剧《来自普莱恩维尔的女孩》(The Girl From Plainville，暂译)。该剧根据米歇尔·卡特的真实故事改编，2017年，卡特(范宁饰)因三年前发短信鼓励男友自杀而被判过失杀人罪，臭名昭著。丽兹·汉娜([华盛顿邮报])和帕特里克·马克曼努斯(《幻想快乐》)将共同撰写该剧剧本。Application layer attacks use more sophisticated mechanisms to achieve hacker targets. Application layer attacks do not use traffic or sessions to flood the network, but slowly deplete resources on the application layer for specific applications/services. Application layer attacks are very effective at low traffic rates. From a protocol point of view, the traffic involved in the attacks may be legitimate. This makes application layer attacks more difficult to detect than other types of DDoS attacks. HTTP flood, DNS dictionary, Slowloris, and so on are examples of application layer attacks.
