According to Mei Xiangrong, Pacific Century's chief tourism consultant, the "Charm Card" program is mainly embodied in three aspects. The first is the Brand City Plan, "Charming China City" and the City Alliance have opened up the brand promotion of the city. CCTV has provided a "media + industry" urban development platform, while "Charming Card" has inserted the wings of the Internet into the development of the cultural and tourism industry. The second is the brand scenic spot plan. We hope to directly connect the scenic spots of the city brand with the "Charm Card" on the basis of the platform of "Charm Card". The third is the brand establishment plan of Charming China City. In the future, we can rely on the "Charming Card" to let the city's characteristic agricultural products really come to the city and go to the dining table.SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.Recently, the number of reflective DDoS attacks using memcached servers has increased significantly. CNCERT has carried out centralized monitoring and analysis on three types of key reflective attacks. This report is a special analysis report on reflective attack resources in February 2018. Focusing on the problem of Internet environment threat management, this paper focuses on the analysis of "what are the important network resources used to launch DDoS reflection attacks". Network resources for reflection attacks include:Altitude (feet above sea level)在全民金融、全民炒股的热潮下，火锅店厨师姚为民也拿出家里的存款、拆迁款和亲戚的借款，凑在一起，参与放贷。一天，姚为民的老熟人装修公司老板刘岩向姚为民借款57万，姚为民被高息诱惑，连续借给刘岩两笔57万现金，却不知不觉中掉进了刘岩精心设计的陷阱，致使其中一笔57万借款血本无归。姚为民追债不成，恼羞成怒，请自称专业追债的黑道人物虎哥帮助追债，却不料，虎哥原来是个冒牌货，钱没要回来，姚为民反被诬为骗子。面对夫妻反目、家庭破裂、亲人相逼，姚为民为要回57万，不惜铤而走险。。。与此同时，小贷公司老板资本之鹰许量与美女借款客户利华公司总经理张嘉仪，情债、钱债纠缠不清，意图通过债转股的方式财色兼收。。。傅吉祥，人称傅老大，因父母早逝，他长子为父带大了三个弟弟一个妹妹，把他们都送进北京的大学。当弟妹们长大成人、事业有成后，他也错过了人生的辉煌时期：因没有生育能力而婚姻失败，失业下岗后成为一名足疗师。但他却有足够的乐观精神去面对一切，仍怀有自己的事业和生活理想——成为一名按摩师和父亲。他阴差阳错与孤独症儿童乐乐相识，一见如故。乐乐的母亲梅好遭到丈夫抛弃，独自抚养乐乐，生活陷入困境。老大救下试图自杀的梅好，认乐乐为干儿子，并收梅好为徒，教她做足疗。三人就此相依为命，在东北小城过着平静的生活。此时居住在北京的兄弟姐妹们为了给过世多年的父母迁坟一起回到东北老家，傅家老二吉安派自己公司吉安集团的行政总监辛雯提前回老家安排行程。老大在二手手机市场被骗，买下小偷偷来得手机，而这部手机正是辛雯的。傅家兄妹在老屋团聚时警察前来调查手机一事，老二吉安觉得很没有面子，一怒之下炒了辛雯。弟弟妹妹们都觉得大哥过得不幸福，都不想让老大再继续做给人摁脚丫子的“下作活”，希望为大哥换个活法，决定带大哥到北京生活。然而，向周夫子磕头道：晚辈林聪，恭喜老大人骨肉团聚。
