The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.《双面玛莎》根据真实事件改编，曾入围2011年圣丹斯电影节和戛纳电影节一种关注单元，影片在圣丹斯公映后备受好评，被认为是2011年的《冬天的骨头》。他不是不懂乡野生活乐趣的人，但她这样一个女子，身穿麻衣，住在庵堂里，夜晚只与青灯木鱼相伴，他只要想一想那副情景，心中就揪痛。无疑会让汉国背上一个抛弃盟友的骂名。特工界的神话叶萧因伤退役后，被逼相亲遇上霸道女总裁“商界王祖贤”张雪瑶，担任她的的王牌保镖，开始一场“小粉拳捶死你”&“未婚妻有毒”的动荡爱情。中海市商场波云诡谲，为了争夺一项医疗技术，一伙杀人如麻的雇佣兵偷渡上岸，震动中海的惊天绑架案正在酝酿中。叶萧也惊奇地恢复记忆，原来他和这群亡命之徒并非第一次交手......II.
