2. Certificate Handling:
When the server provides some UDP-based services, such as DNS, SMTP, NTP, etc., and finds some requests, in which the Response message is larger than the Request message, the Attacker sends a Request message that forges the source IP, and the source IP forges the IP address of the victim. After receiving the Request message, the server replies the "enlarged" Response message to the victim, thus realizing the amplification of traffic. The principle is roughly as follows:

New Zealand is the last land discovered by human beings in the world. Its rich products and magnificent and fantastic geological landscape have attracted immigrants from all over the world, thus giving birth to a colorful, open and inclusive New Zealand culture. More than 1,000 years ago, Maori sailed wooden boats across the sea to come here. More than 700 years later, the European continent's maritime fleet settled here. For more than 200 years, groups of dreamers who have left their homes from Asian and Pacific islands have worked hard here to build and interpret their dreams. This film takes New Zealand's immigration history as a narrative clue and shows New Zealand's unique immigration culture. The inclusive and open multi-culture of New Zealand today is reflected by shooting Maori's life scenes with extremely rich ethnic characteristics, singing and dancing performances, etiquette and customs, and the city features established by descendants of European and Asian immigrants, with the story of local Chinese families as a shooting focus.

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.
