DDOS attacks are among the most widely used technical attack types today. In fact, this attack technique, which has different types, directly accumulates a load on the server and causes it to collapse. It took a very short time for the first hackers to discover this method. It is simply to accumulate loads above the current load weight. As an example, you can consider a water container. A water container can hold 20 LT of water. But if you try to fill 30 – 40 LT of water, all the water in this container will come out. The systems are just like this. If a small website uses hosting that can reach 10 thousand visitors and if we accumulate 20 30 thousand visitors to this network in a short time, that site will collapse in a short time. In general, some systems become unusable due to crashes. However, we can say that there are also robust servers that survive the attacks in just a few hours, which resumes the attacks in a short time.
1What is a DNS amplification attack
These attacks are generally DDOS attack type that is done by using the vulnerabilities of the target server. DNS amplification attack, which is generally leaked to the network weaknesses in the server and sent intense requests in this field, seriously damages the server structure. Especially, it is more difficult to find the network weaknesses of advanced sites compared to other sites, and there are more attacks on smaller sites in this area. DNS protocols bring new updates from time to time. It is normal for you to be exposed to attacks in line with automatic updates made by you in this area. Detecting network vulnerabilities is usually the job of web developers or cybersecurity experts. In this area, you should make sure that there are serious differences between site deficits and network deficits. Because the software method of network vulnerabilities may face a different type of attack than the servers.
2How to protect the DNS amplification attack?
The best method of protection against this attack method is to take an open test. Even the smallest vulnerability will be enough for hackers to attack your site in the network vulnerability tests that you will make from time to time in this area. When your site is attacked, it is actually the simplest way to turn it off rather than wait. If you have a serious audience and need to remain accessible, you can adapt the dual-factor verification system to your website or app. In other words, you can manage to secure your sites in a short time with the applications that show that you are not a robot.
At the same time, if you have been subjected to a serious attack, you may need to shut down your site and identify the target area where the attack was made. DNS amplification attack makes serious attacks with vulnerabilities in this area. DNS vulnerabilities are a useful technique for attacking the target network. Hackers who are experts in this field can also block access with the help of social engineering in a short time.
