Misunderstandings about DDoS attacks

Misunderstandings about DDoS attacks

DDoS attacks are on the rise, and experts are also trying to defeat them. Analysts predict that the global DDoS prevention market will grow by 2013 from 2018 to 19.6%. However, many people do not know how the attack works. The misunderstandings about DDoS mainly include the following:

DDoS attack Flowchart

Error 1: botnets are the source of all DDoS attacks

This is a general belief, but in fact, not all attacks come from botnets composed of PCs. As technology advances, the processing performance and bandwidth usage of high-performance servers increase rapidly. Correspondingly, the development and use of botnets composed of traditional PCs have slowed down.

Error 2: DDoS attacks only consume bandwidth

In fact, DDoS attacks can also be used to consume system and application resources. Therefore, the attack traffic is not the only indicator to determine the attack severity.

Error 3: DDoS attacks are flood attacks.

Flood attacks are DDoS attacks, which most people think. In fact, in addition to flood attacks, there are also slow attack methods. The essence of DDoS attacks we define is to consume a large amount of resources or occupy them for a long time to reject other user services. Flood attacks are used to quickly consume a large amount of resources and send a large amount of data and requests.

Compared with flood attacks, slow attacks are slow but send requests to the target, occupying resources for a long time.

Error 4: If you are not a well-known brand, hackers will not attack you

Assume that my website is small, so I don't need to worry about DDoS attacks. However, if you run a website, even if you get a small income or engage in non-profit activities, you will not be comforted by these wrong ideas: "There are so many websites, most of them are more famous than me, and hackers will not waste their time on me."

In fact, any website can be attacked. When cyber criminals choose targets for extortion, they know that attacks on major websites may be more profitable, but at the same time, costs and risks are usually greater. However, with smaller websites, their defense is generally weak, and attacks are more likely to succeed.

Error 5: Only hackers have the technology to launch DDoS attacks

At present, most hackers' businesses are specialized. Some focus on discovering vulnerabilities, some development tools, some responsible for system intrusion, and some good at account information processing. In fact, many DDoS attacks are initiated by ordinary people renting servers.
