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.

Activity monitor is a device that can detect and interfere with traffic to the server. Like firewalls, it is not a necessary device in network routing. A typical monitor, like the ACK disguised firewall/proxy in 7, has an additional capability, that is, if it finds that the SYN packet originates from an attacker source address it knows, it will immediately send the disguised RST packet to the server. Activity monitors are practical because they are cheap and easy to deploy (compared with schemes based on firewalls and input source filtering), and can still protect the entire server network without requiring each server operating system to implement a terminal-based solution.

新剧《灵界》被制片人描述为相当长一段时期内人们在电视上见过的最吓人的电视剧集。该剧描述一个17岁少年能够看见死者的精灵，一种被称为逝者的东西。这种东西不是鬼魂，不是吸血鬼和狼人，也不是民间传说中任何一种怪物，而是一种全新的东西。活人见不到他们，听不到他们，闻不到他们，也感觉不到他们的存在。但是如今生与死的界限开始模糊，逝者突破束缚进入了活人的世界。一个叫Paul的少年能够用肉眼看到逝者，他和他的朋友Mac将承担起驱除邪灵、保护人类的重任。一开始，Paul总是被世界末日的噩梦惊醒，他的心理医生对此无能为力。后来Paul亲眼见到自己身边被逝者环绕，才明白发生了什么事。与此同时，女主角Sarah能够预见未来，并因此遭到逝者的袭击。当Sarah神秘消失后，她的前夫Mark开始四处寻找她。

1927年对共产党来说是血雨腥风的一年。在不到半年的时间内，中共中央两次被迫迁移。第一次是从上海迁往武汉，第二次则是从武汉迁回上海。两次迁移，都是因为猝不及防地遭到过去的盟友国民党的突然袭击。 中共武装反蒋后把中央领导机关秘密建立在上海。首先是因为中共没有稳定的根据地，只能选择在群众基础较好的大上海；其次是因为上海有租界，租界区华洋杂居、政出多门，各种势力矛盾重重，且租界区不查户口、交通便利。在租界区，国民党的警察、宪兵和特务不能随便执行“公务”，更不能开枪、捕人。租界巡捕房捉到共产党，国民党当局只能通过法律程序进行“引渡”。“国中之国”的这种特性正好可以加以利用，寻找掩护的职业和场所，设立党的机关，进行秘密活动。 在这种错综复杂、暗流涌动的大历史背景下，如何有效地保卫处于秘密状态下的首脑机关，成为中共中央一切工作重中之重。于是，由周恩来首倡，在原中央军委特务工作处的基础上，筹建了“中央特科”这个政治保卫机构。 电视连续剧《江南锄奸》正是以此为背景，表现了那个年代中共特科在党
