Anti DDOS: definition and top of the best solutions

Anti DDoS solutions help protect a website, application, network or data center from denial of service attacks. Find out everything you need to know about the different practices to adopt as well as an overview of the best solutions available.

At a time when the Internet connectivity has become essential for many businesses. DDoS (denial of service) cyber attacks can have serious consequences across all industries. These attacks are designed to shut down a server, network or data center to prevent legitimate traffic from connecting to it.

Even when the time of inaccessibility is very short, only a few hours, the losses generated can be colossal for the company as well as the collateral damage. According to a study conducted by Cloudflare, the average cost of infrastructure failure for a business is $100,000 per hour. That is why anti-DDoS measures are now indispensable.

Anti DDoS: what is it?

Simply put, the term “anti DDoS” refers to all hardware, software and measures taken by the IT department, a data center, an internet service provider or a cloud provider to prevent or mitigate denial of service attacks.

The the most basic anti DDoS measures are preventive and can be supported by an experienced IT team. For example, this may involve strengthening firewalls and other traditional protection systems through better configuration.

Intelligent firewalls can also be used for web applications to test requests before accepting them. Ports that are frequently attacked when not in use should also be closed. In addition, it DDoS monitoring software is also available. to filter out malicious traffic. However, these tools are useless in the face of a large-scale attack.

On the other hand, Mitigation usually requires a combination of software and hardware systems. in order to keep malicious traffic away from servers and network infrastructure in order to inspect and isolate them and allow only legitimate access requests.

The first solution is to install a hardware anti DDoS solution. However, these solutions are extremely expensive and only work against certain types of attacks. Several companies now offer anti-DDOS systems that combine hardware and software.

The second, more effective alternative is to use a third party mitigation company to delegate this task to him. When an attack is in progress, all traffic is instantly redirected away from the Data Center and to the Cloud where anti DDoS programs can inspect its origin and nature. Only legitimate visitors will be redirected to their destination. This process is so fast that users will not even notice that a DDoS attack has been launched.
