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.

Before performing an SSL data transfer, Both sides of the communication must first shake hands with SSL, The encryption algorithm has been negotiated to exchange the encryption key, Perform identity authentication, Normally, This SSl handshake process only needs to be performed once, But there is a Regegotiation option in the SSL protocol, It allows renegotiation of the secret key to create a new key, The attacker repeatedly carries out the key renegotiation process, and the key renegotiation process requires the server to invest 15 times more CPU computing resources than the client. In addition, even if the server does not support Renegotiation, the attacker can still create similar attack effects by opening a new SSL connection separately.
