Behavioral pattern is an abstraction of dividing responsibilities and algorithms among different objects. Behavior patterns are not only about classes and objects, but also about their interactions. Behavioral patterns can be divided into two types: class behavior patterns and object behavior patterns.

Zhang Yange: Irregular reviews, maybe two months, maybe half a year. This year, we have prepared a bonus of 10 million yuan to reward the content. There is no ceiling on individual awards. If we think the manuscript is worth 200,000 yuan, we will also send it. Of course, it is not necessary to send out all the 10 million yuan, depending on whether the reporter has the ability to take it away. The total amount of awards in the first phase is also far more than one million.

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.
