DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.紫霞与青霞（朱茵 饰）本是如来佛祖座前日月神灯的灯芯（白天是紫霞，晚上是青霞），二人虽然同一肉身却仇恨颇深，因此紫霞立下誓言，谁能拔出她手中的紫青宝剑，谁就是她的意中人。紫青宝剑被至尊宝于不经意间拔出，紫霞决定以身相许，却遭一心记挂白晶晶（莫文蔚 饰）的至尊宝拒绝。后牛魔王救下迷失在沙漠中的紫霞，并逼紫霞与他成婚，关键时刻，至尊宝现身。故事发生在中国一个典型的中等新兴工业城市--天都。天都市龙腾集团董事长、副市长聂大海之子聂明宇是一个全省闻名的青年企业家，但是暗地里，他却操纵着天都市最大的地下黑社会活动。他设立赌场，有计划有预谋地拉拢腐蚀天都市的干部队伍，并利用父亲的市长背景，大肆收买海关各级人员，走私贩私，牟取暴利。他的副手张峰更以为人阴损、手段毒辣著称于世。在这些人的“苦心”经营下，龙腾集团逐渐发展壮大，但很明显这其实是一个不折不扣的、具有黑社会性质的犯罪团伙。越国大军正面由河内郡向赵地发起进攻，由越王尹旭亲自率军出击，许忻任亲卫将军，大将军苏岸为前锋，率军发起进攻。全国首档原生二胎观察真人秀，节目邀请来自四个原生家庭的手足，记录他们彼此陪伴共同成长的美好瞬间。嘉宾观察团以手足情感代入其中，引发共情和讨论。周菡被他两句话就问住了，气呼呼地瞪着他看了好一会，才道：好吧。电影《窃听风云3》讲述了香港一个豪门望族在涉足房产黑幕交易后的浮沉故事。香港新界陆氏家族在此盘桓百年，某日，同村的罗永就（古天乐饰）醉酒撞死了异姓兄弟陆永远，从此与陆永远之妻月华（周迅饰）结下不解之仇。5年后，罗永就出狱，看到陆家风云变幻，陆氏家族大家长陆瀚涛（曾江饰）及其女陆永瑜（叶璇饰）已经坐拥新界最大房产公司，并开始结交内地政商；陆家兄弟陆金强（刘青云饰）等人在新界疯狂收购土地扩张势力。就在此时，香港房产巨鳄邀请罗永就“共商大事”。同时，神秘人阿祖（吴彦祖饰）透露给月华，她丈夫的死与陆家的土地交易黑幕有关，并且多方势力都瞄准了月华和村民们坚守的百亩良田，要想在这场欺天阴谋中复仇，就必须按照他的指示去做……一场爱恨交织，钱权阴谋的悲欢故事揭开序幕。
