Dirty play by competitors, blackmailing or even training - hackers today can put down dedicated servers for a large online store, or VPS for the website of a small company. They use the so-called DDoS for this purpose. Therefore, everyone who cares about the safety of your business should be prepared for this attack. To do this you need to know what is a DDoS-attack, the types of it, and most importantly: what server protection from DDoS is effective - and how to deal with this with help from our article!
DDoS is short for Distributed Denial of Service. What happens is that the server receives too many requests from users at the same time, literally in thousands, and the channel becomes full, and the equipment stops responding - "denial of service". This leads to reduced traffic, financial and reputational losses. Important: a DDoS attack is launched from many real, virus-infected devices in a botnet controlled by a hacker (hence the term "distributed" because there is a simple DoS, with requests from a single computer). This makes the attack larger and more difficult to detect and neutralize.
There are many ways to artificially overload someone else's server - and they are very diverse. For a better understanding of the situation it is worth knowing at least the popular types of DDoS attacks:
It is important to remember that these are only the most common and understandable types of DDoS attacks, but in reality there are many more, and their nature can vary quite noticeably. That is why we could write not just a short article about them, but at least a manual!
DDoS attacks are distinguished by the OSI network model, Open Systems Interconnection, which defines levels of system interaction. There are 7 levels in total, and each level has its own type of server attack:
As you can easily guess from the above two lists, the most common types of DDoS attacks according to OSI are Layer 3, Layer 4 and Layer 7.
It is worth noting that massive attacks on servers and websites can still be divided by the method of exposure to the "victim''. There are three variants:
Countering distributed attacks by hackers on servers must be truly comprehensive. Therefore the work should be divided into two equally important areas.
Any problem is easier to circumvent than to correct. And while it is impossible to avoid an attack, it is possible to reduce the likelihood or consequences. To do so, you need to:
It is impossible to describe universal ways to combat an attack on a website, server or corporate network - everything is individual. But there are some general principles:
The last point is most important for protection against intruders and is already at the level of renting VPS-servers or dedicated servers.
