On the one hand, the core components of the network infrastructure have never changed in the past ten years, which makes some discovered and exploited vulnerabilities and some mature attack tools have a long life cycle and are still valid even today. On the other hand, the rapid development of the application of the Internet seven-layer model has diversified the attack targets of DDoS. From the web to DNS, from the three-layer network to the seven-layer application, from the protocol stack to the application App, the endless new products have also given hackers more opportunities and breakthrough points. Moreover, DDoS protection is a project with unequal technology and cost. Often, the construction cost of a business's DDoS defense system is larger than the cost or benefit of the business itself, which makes many start-up companies or small Internet companies unwilling to make more investment.
-I think this is a sense of acquisition. The sense of acquisition will give people enrichment, enrichment and achievement. Human beings' natural possessiveness will subconsciously suggest to themselves in their blood that if there is no harvest today, then today's day will be a white one. Of course, this harvest can be material or spiritual. The sense of acquisition can also be tangible material, and of course there are also spiritual gains that cannot be seen, but can make your heart feel full, your thoughts feel rich, and your emotions feel high.

Buckeye flowers have different colors, generally yellow, orange and pink. Why do flowers of the same plant have three colors? This is actually the way Buckeye flowers tell bees and bumblebees whether they are popular at this moment. Those flowers with nectar and waiting to be pollinated will appear yellow, which is an irresistible color for insects. When pollination is over, the flowers will slowly turn red, because bees and bumblebees cannot see red, thus the flowers will disappear in their eyes.
The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.

Of course, the above calculation methods do not consider range injury. Considering that the scourge has been grinding the single boss for a long time, the above affixes or special effects are all fixed damage increases, the income is balanced and stable, and it is worth getting close to the full value. After all, it is useless for the boss that does not recruit small monsters to have a higher range of injuries. After these values are filled, you can consider adding some range injury affixes, such as the position of shoulder gloves weapon. Obviously, to lose strength or 1000 physical fitness, you need a high peak to make up for it. In the novice stage, it is recommended to collect equipment capable of range injury instead of using it directly.
