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.)
In the case of a reflection attack, An attacker uses a controlled host to send a large number of packets, The special feature of these packets is that the destination IP address points to the server, router and other devices as the reflector, while the source IP address is forged as the IP address of the target. When the reflector receives the packet, it will think that the packet is a request sent by the attacked bird, so it will send the corresponding data to the target.

At that tail of the warhead, the drag armour-piercing firebomb is filled with a drag agent and a fireagent, Under the pressure of propellant propelling warhead, it will spontaneously ignite to produce open flame, So it can break through the oil drum and ignite or detonate the gasoline. However, the old-fashioned traced armour-piercing firebombs have obvious trajectories due to traced light when they are launched. Therefore, it is very easy to expose oneself while pointing targets to friendly forces. Therefore, the new tracer armour-piercing firebombs now equipped all start to burn and emit light only after the projectile flies out of the muzzle for a certain distance (the generally set safe distance is 100 meters, which makes it impossible for the enemy to judge the firing position with tracer ammunition, while targets within 100 meters do not need to be indicated by tracer), The principle is generally to ignite the tracer and combustion agent carried by the projectile by accumulating the heat generated by the warhead's friction with the air after flying for a certain distance to a certain extent.

秦霖被小丫头那清澈的目光看得不自在,忍不住道:怕了?紫茄沉默,好一会才怯怯地问:你又不是坏人,为何要学混世魔王干坏事?你以前……很讲道理的。

One of them is called Small and Micro Finance. I look at the strength behind it and I don't know that it is currently in a thunderbolt. The fund originally expired on July 16. Later, when I went to the platform and saw it on the 15th, I issued a liquidation announcement, promising to honor the payment plan in 10 installments and 10% in each installment. I feel that the platform is still very conscientious.
First of all, I would like to thank Jiguo Net very much for giving me the opportunity to experience AnchorChef's low-temperature slow cooking machine. After two days of trial, I have made hot spring eggs, sirloin steak and lamb chops. I have basically become familiar with the operation method of the slow cooking machine and accumulated some experience in use. I would like to make a brief introduction and share my own experience. This report is divided into three parts. After a simple blueprint, let's officially enter the text.
