DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.

Launching reflective attacks requires finding a large number of transmitters on the Internet. Some kinds of reflective attacks are not difficult to implement. For example, for ACK reflective attacks, only servers with open TCP ports on the Internet need to be found, and the existence of such servers on the Internet is very extensive.

When an event is propagated and a function that can handle it is found, then we say that the function captures the event.
Conclusion: As the name implies, singleTop, if the current instance is at the top of the current task stack, it will be reused directly to test scenario 1. If the current instance is no longer at the top of the stack, create a new instance, such as Test Scenario 2, because it jumps from FirstActivity to SecondActivity every time. Although the SecondActivity instance already exists at the time of jumping to SecondActivity for the second time, another SecondActivity instance is created because it is not at the top of the stack.
