When the client SYN packet arrives at the filter gateway, the SYN agent does not forward the SYN packet, but actively replies the SYN/ACK packet to the client in the name of the server. If the client's ACK packet is received, it indicates that this is normal access. At this time, the firewall sends the ACK packet to the server and completes three handshakes. The SYN agent actually replaces the server to deal with SYN attacks. At this time, the filter gateway itself is required to have strong ability to prevent SYN attacks.《味库美食视频》是一档美食分享类节目，这里有海量菜谱，菜品智能搭配，主要满足年轻人想下厨房学做饭的需求，带你一起感受食物的力量和美好。阴霾天空下，一个面具人诡异地站在摩天大楼天台边，一场性命攸关的神秘“要挟”打破了城市的安宁，女记者柳依人(阎娜饰)以绝佳的职业敏感度，展开了对面具人真实背景的追踪。而此时，本市著名企业名流心理学博士常思远(于和伟饰)却被莫名的恐惧冲袭。面对妻子柳依人追击真相的正义感，常思远却暗中窥视面具人的一举一动。在这场心理博弈中，伴随面具人幕后策划者的步步紧逼，一个疯女人、一个苦命村妇和一个惨遭谋算女子的三段情债内幕不断曝光，让常思远的娇妻柳依人，深陷真正“面具人”如影随形的“梦魇”中，而这位被世人赞赏的社会名流——常思远博士，也在人性危机的心魔中，走向“发家原罪史”的自我审判之路！一番人性危机的暴风骤雨，正不断惊醒哪些仍然放肆寻找成功捷径的贪婪灵魂！6.4. 2?

The special feature is that the reflector has the function of amplifying network traffic and is a common technical means in DDoS. Its basic principle is relatively simple. For a C/S service, if the Server-to-Client Response message is larger than the Client-to-Server Request message, the traffic is enlarged. In order to use amplification technology in DDoS, one condition needs to be met, that is, the services provided by Server are based on connectionless protocols such as UDP.
