Taking into account the fact that DDoS attacks are becoming more and more common every day, we need to consider this issue in more detail. DDoS is a method of attacking a website in order to block access to it by real users. For example, if a bank site is designed to serve 2000 people at the same time, the hacker sends 20 packets per second to the service server. Naturally, the channel will be overloaded and the bank's website will stop serving customers. Therefore, the question arises:How to protect your server from DDoS attacks? '.
To begin with, you need to understand that huge computing power is needed to successfully carry out an attack. For an ordinary computer, like a hacker's provider's channel, will not be able to withstand the load itself. For this, a botnet is used - a network of hacked computers that carry out the attack. At the moment, IoT networks - the Internet of things - are most often seen in attacks. These are hacked "Smart Home" systems - devices connected to the Internet. Alarm systems, video surveillance, ventilation and much more.
Therefore, it is important to understand that it is unrealistic to fight off a serious DDoS attack alone. The network equipment, like the server itself, simply cannot withstand the force of this attack, does not have time to filter the traffic and "falls down". And real users at this time will not be able to access the site, and the business reputation of a company that cannot even organize the work of its site will be tarnished.
And that is not all. Search engines, puzzled by the absence of a site in the index, will lower its position in the search. It may take up to a month to restore the initial positions. And for large companies, this is like death. This means either big losses or even bankruptcy. Therefore, do not neglect protection against DDoS attacks.
There are 4 ways to protect against DDoS attacks:
- Self defense. Write scripts or use a firewall. A very inefficient method, it can only work against attacks on a small network of up to 10 machines. Stopped working in the early 2000s.
- Specialized equipment. The device is deployed in front of servers and routers, filtering incoming traffic. This method has 2 drawbacks. Firstly, their maintenance requires expensive highly qualified personnel. Second, they have limited bandwidth. If the attack is very powerful, they will freeze, unable to cope with the load.
- ISP protection. Unfortunately, in order to cope with the latest DDoS attacks, the provider needs to purchase expensive equipment. Many providers strive to sell their services as cheaply as possible, so they are not able to provide reliable protection against serious DDoS attacks. A partial way out of the situation is several providers who, in the event of an attack, repel it with joint efforts.
- Server protection service from DDoS attacks from ProHoster. Since the bulk of the equipment is located in the Netherlands, we will use the largest bot cleaning network in Europe, also known as the DDoS protection cloud. This network has already had experience successfully resisting 600 Gb / s attacks.
