Since http is based on tcp, You need to complete a three-way handshake to establish a tcp connection before you can start http communication, Therefore, when http flood attacks are carried out, it is not possible to use forged source ip addresses to launch attacks. An attacker will typically use an http proxy server, Not only can the source be hidden from being traced, It also improves attack efficiency-after the attacker connects to the proxy server and sends the request, You can directly disconnect from the proxy server and start connecting to the next proxy server, At this time, the http connection between the proxy server and the target web server is still maintained, and the web server needs to continue to accept and process data. An efficient http flood attack should continuously send http requests for different resources and pages, and request resources that cannot be cached as much as possible (such as keyword search. User-related information, etc.)

This class can meet the basic requirements, but if we put a class like this without thread safety protection into a multi-threaded environment, there will definitely be problems. How to solve them? The first thing we think of is adding the synchronized keyword to the getInstance method, as follows:

The intermediary mode is also used to reduce the coupling between classes, because if there is a dependency relationship between classes, it is not conducive to the expansion and maintenance of functions, because as long as one object is modified, other related objects have to be modified. If you use the mediator mode, you just need to care about the relationship with the Mediator class, the relationship between specific classes and the scheduling to the Mediator, which is a bit like the spring container. Let's look at the picture first:

那是在一亿七千五百万年前，三颗陨石由外太空飞来，坠落于三个不同的地方化身成不同的人物。每二亿年，太阳黑子便会爆发产生宇宙风暴，天界众神的力量便会减弱，而代表黑暗力量的天魔亦会出现。要打败天魔，惟一方法是要某年某月某日某时某刻某分某秒出世的人，由其中一颗陨石的化身护送他到西天取《三藏真经》；该石须在取经过程中找到另外两个陨石的化身，再待天魔出现时，借真经力量，三石合一，才能战胜天魔，否则天地将会变成鸿蒙一片，返回混沌世界。
At present, there are many open source DDOS attack tools (low attack cost is also one of the reasons why DDOS attacks are easy to occur), but there are not many DDOS attack defense tools. Fastnetmon is an efficient analysis tool for DDOS attacks based on various packet grabbing engines, which can detect and analyze abnormal traffic conditions in the network and notify or block attacks through external scripts. A visual DDOS security early warning system can be built by integrating InfluxDB and Grafana.

Some DNS servers will recursively send query requests to the upper DNS servers and wait for a response when they cannot obtain the resolution results of domain names, which further increases the resource loss of the servers.

Security executives are never willing to talk about these attacks because they do not want their remarks to attract more attention to the enterprise. They even worry that providing basic information on defense strategies alone will be enough to attract attackers to come and find security vulnerabilities.
