In today's globalized society, DDoS protection has become very important. While information and communication technologies such as cloud computing, 5G, and AI have brought convenience to everyone, they have also created many gray industries to deliberately embezzle broadband networks and disrupt normal operations. Among them, the dark killer in the network security industry-DDoS attacks, can be said to be the most tricky and hopeless attack method in network operation and maintenance.
In August of this year, first the Belarusian Security Committee and Ministry of Internal Affairs website were attacked by DDoS, which directly affected its presidential election, and then the New Zealand exchange suffered a DDoS attack that interrupted its service, resulting in customers completely unable to trade stocks.
According to a report by the Russian Satellite News Agency on August 9th in Moscow, the Belarusian National Response Center of Computer Time issued a message that the equipment on the website of the Belarusian National Security Council and the Ministry of Internal Affairs was attacked by DDoS. The attack continued until the evening of August 8. On the 9th, the peak attack traffic was 203GB per second! To make its DDoS protection measures to be tested, the local government of Minsk, the capital of Belarus, decided to completely shut down mobile communications and the Internet on the day of the presidential election. In the early morning of August 10, 2020, when the Belarusian Central Election Commission released the stage of the presidential election As a result, the citizens boiled! Especially the supporters of Tikhanovskaya, they can't believe that Lukashenko can get 81% of the votes, while the opposition's support for only 8%, but everything has been settled.
Coincidentally, New Zealand Exchange (NZX), the only registered stock exchange in New Zealand, was also attacked by a distributed denial of service (DDoS) in August, which caused its service to be interrupted due to insufficient DDoS protection. According to the stock exchange, this DDoS attack is a malicious attack from overseas. The purpose is to destroy the normal traffic of their servers through a large amount of network traffic, directly affecting their network connections. Because the affected systems include the New Zealand Exchange website and market announcement platform, they decided to immediately stop trading in the cash market! This incident directly caused the financial market to fall into chaos. Although DDoS protection methods continue to progress and develop, we still need to improve. Note that this type of DDoS attack is still very common, and may even cause access to important platforms to be reduced or completely impossible. use.
So, what exactly is DDoS? How did it launch the attack? DDoS is also known as Distributed Denial of Service. The full name is Distributed Denial of Service. In simple terms, it is the use of reasonable requests to cause resource overload, resulting in unavailability of the service, that is, when the server is busy responding to false requests, it has no time to respond to normal user access Demand. Specifically, it generally means that an attacker uses a virtual IP source, commonly known as "broiler", to initiate a large number of requests to the target website in a short period of time, consume the host resources of the target website on a large scale, and cause the server to crash and fail to respond and access. .
While DDoS attacks endanger the Internet, many security experts are constantly studying DDoS protection methods. The first domestic DDoS protection products and services appeared in about 2002. Since then, the offensive and defensive sides have been declining and fighting endlessly. Many manufacturers have launched their own DDoS protection products and services to deal with DDoS attacks. Now DDoS protection is an issue that enterprises have to consider.
