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.

Data show that there were more than 6,000 companies engaged in private lending intermediary business when P2P platforms were in hot demand in China.

Auction and loan: unsecured and unsecured mode. Auction and loan was established in Shanghai in 2007. It is a typical P2P online credit platform in China and can be used as a typical sample of P2P websites in China. Auction and loan use competitive bidding to realize the online lending process. The loan interest rate is determined by the supply and demand market of the borrower and the bidder. The enterprise does not charge other fees, and the main profit comes from service fees. The main process is as follows: the borrower releases the loan information, lists the relevant information such as the reason and amount of the loan, and gives the highest interest rate. Investors participate in the bidding, and the person with the lower interest rate wins the bid. The web page will show the borrower's loan progress and the number of bids completed. If the total amount of bid funds meets the needs of the borrower during the fund raising period, his loan will be declared successful. If the required funds cannot be raised within the prescribed time limit, the loan plan will be suspended. This mode of risk control has two characteristics:

Today's problem mainly involves several: objects, triggering events, capturing events, executing processing, and blistering. This is actually the whole process of JS execution. The process of bubbling is very interesting. In fact, it is like a glass of water, but this glass of water is hierarchical, and the bottom is the object of the current trigger event. Then the higher the range, the larger the range. The top layer must be window and the penultimate layer must be document. In the process of floating up, the bubble will judge whether the layer currently reached has a binding event handling method. If there is any, the corresponding processing is executed. If not, it will continue to blister. Until you reach the top window window layer. We can do corresponding processing at any layer to prevent the event from continuing to bubble. The method is the method that calls the event object to prevent blistering. Event.stopPropagation (); The following is a process method written to verify JS event blistering.
