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.

"I personally feel that there is still a little luck in this, After breaking up the colony, For a few more minutes, I don't know, Because this is the first time I have met such an 'opponent', No one has experience, Anyway, one is counted as one, It is true that there is no end to shooting with guns. Fortunately, there were flamethrowers prepared to counter the impact on the position at that time. The model I remember was 74, At that time, it was still a relatively new model. In terms of performance, The direct firing distance of '74-jet' (abbreviation of 74-type flame thrower) is about 50-75 meters. If the soldiers who operate it are not specially trained, Generally, only straight-line targets can be hit, It's a little bit of a slope, But in the hands of specially trained veterans, '74 Jet' can fire into that air, Although the range is much less than that of direct shooting, Only 25-30 meters, But after all, he didn't take it to the plane, It is used to deal with enemies in low-rise buildings in street battles. Therefore, it is enough, but it is quite dangerous to spray high-altitude targets with flamethrowers. After all, the fuel sprayed out is liquid. Once the distance and wind direction are not grasped well, it is easy to let the fuel sprayed out fall back again. If it accidentally splashes on oneself, it is really a "fire".
