DDoS (Distributed Denial of Service) is a kind of attack that is difficult to prevent in DoS family. The attacker first controls a large number of broilers and then sends a large number of requests to the target server, resulting in the target server being unavailable. Here we cannot help asking how the attacker obtained a large number of broilers. Attackers will implant some malicious codes into some APP or websites. For example, when users use this APP or website, they will automatically request this website. If there are many active users of this APP or website, then this website will receive many inexplicable requests. This requires us not to browse some unknown websites and download APP from unknown sources in the process of surfing the Internet at ordinary times.Receiver: Receiver一部父子亲情真人秀《爸爸去哪儿》，在中国掀起收视狂潮和广泛热议。明星爸爸们的舐犊情深，和萌娃们天真可爱的俏皮模样，给观众留下了深刻的印象。2014年伊始，该档真人秀强势走上了大银幕。 此次外景地挪到了广州长隆野生动物园林志颖、田亮、王岳伦、张亮和郭涛，带着他们的小宝贝小小志、田雨橙、王诗龄、张悦轩和郭子睿来到了这片野生动物的王国。在代理村长李锐的安排下，大人和孩子开始他们新一轮的任务......翘儿盘算起来，县试快，考完没两天就发榜，咱们准备多少卖？杨长帆看着诸多贝壳呢喃道：我就说个大概，这次咱们做状元铃50个，平安、丰收各20个，富贵、求子各10个，其它你有功夫有心思，再来个什么‘定情‘长寿‘壮阳之类的，我也没意见。《你们被包围了》以江南警署为舞台，以四名重案组新人在组长指导下成长并展开一连串精彩搜查为背景，讲述外形帅酷、外冷内热的高智商新人警察殷大邱，与一名呆萌善良、纯真深情的美丽新人女警鱼秀善之间恩怨缠绵的青春罗曼史，并伴随动人心弦的案件侦破及人物的感人成长历程
