In the Internet era, the text data and audio and video data we obtain are from the server in the computer room. Webmasters provide users with services such as network content and network applications, so as to obtain profit remuneration. However, there are always some criminals who will resort to various means to prevent the normal operation of the webmaster's server for personal gain, including DDoS attacks.
DDoS attacks, distributed denial-of-service attacks, use a large number of controlled computers or botnets to send a large number of requests, exceeding the carrying capacity of the server, so that the server cannot respond to the requests of legitimate users normally. We get network data from a server, like going to the supermarket to buy something. The criminals found a group of people who did not buy things to maliciously block the door of the supermarket, and users who normally purchased goods will not be able to enter the supermarket to buy goods.
DDoS attacks are a worldwide problem, and the frequency and scale of DDoS attacks are increasing as the Internet becomes more widespread and dependent. This attack method is simple and crude, and it is difficult to defend against, causing huge losses and confusion to Internet service providers, enterprises and individuals. While there are many defense tools and techniques that can be used to deal with DDoS attacks, they can come at a high cost, such as firewalls, intrusion detection systems, load balancing, and more.
At the same time, attackers are constantly improving their attack methods, constantly looking for new vulnerabilities and weaknesses in the server. Therefore, defending against DDoS attacks requires an ongoing investment in research and money. To put it bluntly, the confrontation of DDoS is also a head-to-head battle between money and money. In addition to technical defenses, legal and law enforcement agencies also need to strengthen their efforts to combat cybercrime to deter and punish.
