The essentials on DDoS attacks

DDoS attacks are very easy to implement and every year millions of websites around the world are affected and the number of attacks is increasing. DDoS attacks seem to be an inevitable corollary of online business: The more successful your website is, the more likely it is to be attacked sooner or later. However, you can reduce the probability of a DDoS attack on your site. What is a DDoS attack, you may ask? This article explains how DDoS attacks work.

What is a DDoS attack?

DDoS stands for Distributed Denial of Service, but is often just called denial of service. For more information, why not try this out A DDoS attack involves briefly flooding a website with requests to overload the website and cause it to crash. The "distributed" element means that this attack comes from multiple places simultaneously, unlike DoS, which comes from a single place. If your site experiences a DDoS attack, you will receive thousands of requests from different sources over the course of several minutes and sometimes hours. 

How does a DDoS attack work?

Network resources, such as web servers, can only handle a limited number of requests at a time. In addition to the server's bandwidth limitations, the link connecting the server to the Internet has limited bandwidth/capacity. If the number of requests exceeds the maximum bandwidth of the infrastructure element, the following service-level issues may occur. Requests from some or all users may be completely ignored. Usually, the attacker's goal is to block Internet resources (total denial of service). The attacker may also ask for money to stop the attack. In some cases, a DDoS attack may also be an attempt to defame or damage a competing company.

Why do companies rely on professional hosting companies to host their websites?

Increased demand for bandwidth and server management prices explains why most companies rely on professional hosting companies to host their websites. A hosting provider is a company whose aim is to provide users with websites designed and managed by third parties. In this case, a computer is connected and linked 24 hours a day to the Internet (e.g., a web server) via a high-speed connection (a few mbps) that: HTTP server (often apache), cluster server, database server. Anti-malware solutions protect websites, applications, clusters or data centers from psychological denial ware.
