CSRF Vulnerability DefenseIn TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue). 她30岁左右的年纪却承受着生活的重压：儿子年幼、婆婆股骨头坏死病退在家、丈夫所在的企业倒闭，情绪低落。而乐观的顾菲并没有抱怨一个人养家的辛苦，对生活一直抱着积极乐观的态度，与丈夫十分恩爱。不料，一场车祸却偏偏降临到这个本已艰难的家庭——顾菲的丈夫因车祸丧命……A3.1. 5 Thoracic examination. 在一个神佑之地，一个被邪恶侵蚀的国王企图抢夺人鱼族生命之泉获得永生，危难之时独行侠阿凯、穿山侠裤衩、弹簧侠长脚、熊猫侠老白联手开启神秘的生命之泉拯救之旅
