Many people may not know that at the beginning of this year, two large-scale ddos attacks have occurred abroad. However, just a few days ago, the well-known Cloudflare network company in the United States was hit by a large-scale ddos attack. The attackers this time targeted the company's data centers in Europe and the United States. Afterwards, after data analysis, it was found that the total amount of this attack did not exceed 400 gigabits. It can be seen that this attack once again refreshed the historical record.
From the current point of view, not only the scale of ddos attacks is increasing, but also its attack methods are constantly changing and becoming more complex. It targets different websites and has different types of attacks. It is roughly divided into three types:
1. Simple and rude
To speak of simple and rude attacks, they are basically UDP Flood, ICMP Flood, and NTP Flood. They send a large number of data packets to the target website, occupy normal bandwidth resources, and act as guards for normal requests, so as to destroy the attack. Effect, this is the most simple and rude effect, although it is simple but not easy to deal with, many websites have suffered from this poison.
2. More skillful
Such as cc attack is a skill type. He can simulate a normal user's request to visit a website, but it is actually a forged legal data packet, which occupies a large amount of CPU resources and causes server business interruption. This type of attack is most closely related to the business of the website, and it can sustain a long-term high-intensity attack.
3. Hybrid
Mixed attacks are well understood, that is, according to the situation of the website, a variety of attacks are mixed together to attack the target website. It is generally selected during the activity of the website, because such a website itself has a large amount of traffic, and it is easier to achieve the ideal effect of the attack.
