II. General Methods for Determining Minimum Wage StandardsSYN 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.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.哈莱姆第二季教父发现坎比·约翰逊与纽约犯罪家庭搏斗，以控制利润丰厚且凶残的“法国联系”，即从马赛到纽约港的海洛因管道。Bumpy拥有一个分销集团，其中包括来自美国其他主要城市的黑人犯罪头目，他从朋友Malcolm X传递的黑人经济民族主义信息中得到了启示。他的雄心勃勃的计划将面临挑战，不仅是意大利人，但他的妻子梅梅，女儿伊莉丝，对手亚当克莱顿鲍威尔，检察官罗伯特摩根索，甚至马尔科姆本人。《哈林教父》再一次探讨了1964年这个多姿多彩、动荡的年代，黑社会犯罪与公民权利的冲突。回头我表弟还不被人恨死。本剧是继英雄一、二季后又一力作，情节环环相扣，让我们沿着上面的蛛丝马迹来寻找英雄之路，上一季末Peter在Hiro的帮助下毁掉病毒，Hiro将Adam送回过去，一切看似恢复太平... 　　然而，Niki为救Monica消失在爆炸的火光当中，Nathan也在记者会上中弹生死未卜一波未平，另一边Sylar已借Claire的血液重获新生，更加黑暗的旅程才刚刚开始... 英雄们将面临抉择，究竟是谁走向了邪恶?
