DDoS attacks: What are the targeted elements and how to protect yourself from a DDoS attack ?

Distributed denial of service attacks or DDoS are becoming more and more common with the advent of the Cloud. They consist in making a service unavailable by preventing users from accessing it, which creates exponential expenses for companies. Thus, DDoS attacks cause very important financial costs in terms of restoration, loss of productivity and opportunities for companies. Discover in this article, the different tips to apply to protect yourself from such an attack.

The different equipment victims of DDoS attacks

DDoS attacks are carried out through computer networks. But, a protection ddos does not consist in just blocking IP addresses since this trick simply allows to limit them. 

Moreover, these attacks affect specific computers, an entire network, printers, alarms, laptops connected to an infected network. In addition, they can affect bandwidth, CPU time, disk space, a computer's operating system or routing information.

Various strategies to avoid DDoS attacks

It is very difficult to block a distributed denial of service attack, as the company is required to deal with multiple hostile machines at different addresses. To this end, the prevention of a DDoS attack must focus on consolidating the security level of the machines connected to the network in order to avoid a compromise of a machine. Indeed, the protection against a DDoS attack takes into account two essential elements.

The first one consists in setting up an architecture composed of several servers allowing the client service to accomplish the same task. This allows for a good distribution of access points to offers and services. Because following an attack, customers are confronted with a slowdown rather than a stop of service. The second element is the implementation of a buffer server, called "cleaning center" in order to filter and clean the traffic so as to prevent threats from affecting the server.
