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.

Generally, they do not participate in the audit and have no contract with the borrower, but only a creditor's rights transfer contract with Yixin's third party. In this way, lenders will have great risks. Therefore, in order to protect the loan safety of the lender, Yixin promised in the contract with the lender that in case the loan is not repaid, Yixin will pay the insurance money withdrawn by the company to compensate all the principal and interest of the lender. This is the biggest guarantee for the lender. Risk control is a powerful guarantee for repayment. Yixin's decentralized loan and monthly repayment system have ensured effective repayment to a greater extent. In addition, Yixin requires a face-to-face meeting when reviewing the borrower. Therefore, Yixin has set up offices in 15 cities, one of its purposes is to meet with instant noodles. In the face-to-face meeting, I personally presented the original of various certificates and asked about the use of the certificates in person, thus better ensuring the authenticity of the borrower. Judging from its strong control over the lending process, Yixin is mainly a way for P2P enterprises to determine the interest rate of borrowers according to their credit rating, so Yixin belongs to composite intermediary P2P.

Here, the filter gateway mainly indicates the firewall, and of course the router can also become the filter gateway. Firewall is deployed between different networks to prevent foreign illegal attacks and the leakage of confidential information. It is located between the client and the server. Using it to protect SYN attacks can play a very good role. Filter gateway protection mainly includes timeout setting, SYN gateway and SYN agent.

The top ViewGroup here is MainActivity (DecorView). First, the down event is sent to the child view, then the child view does not consume it, and then it is handed over to the parent view for consumption layer by layer. Finally, no one consumes it back to MainActivity, and the down event ends. From the above source code analysis, it can be seen that the mFirstTouchTarget is empty at this time. If the move event comes, the else interception event of the source code number 2 part will be directly executed, so the log of the subsequent event will not be distributed as above (and the log of the onInterceptTouchEvent () method will not be called at the same time). If the child view consumes the down event, mFirstTouchTarget is not empty, and the process of subsequent events is similar to down. Readers can modify MyView's onTouchEvent () to consume the down event and try to consume the down event.
