A DDoS attack (denial of service attack) is carried out with the aim of changing the availability of an application or platform. When the latter is attacked, its operation is affected. This article presents some powerful techniques to protect against these attacks.
Differentiating between normal and abnormal traffic
Denial of service attacks are becoming more and more frequent. It is therefore mandatory to take appropriate measures to fight against these attacks. You don't know what is a ddos attack ? Visit the site to understand its severity. One of the techniques that works effectively against these attacks is the ability to distinguish between normal and abnormal traffic. To do this, it may happen that a host is affected by several higher level traffic. In this case, only traffic that can be used without a change in its availability should be accepted. This is known as rate limiting. In addition, some techniques rely on the analysis of individual packets to accept only legitimate traffic. For this reason, it is recommended to understand the characteristics of the best traffic received by the target very often.
Effective reduction of the attack surface
Among the most common techniques, reducing the attack surface that can be targeted is also effective. This technique allows the creation of protections in a single location. It also limits the possibilities of attack. The aim is to protect communications. When communications are protected, the points of attack are reduced. This can be achieved by placing the IT resources behind the load balancers on the one hand. On the other hand, firewalls can be used. Firewalls are useful for checking the traffic of your applications.
Protection through firewalls
Some attacks target sophisticated applications. This could be cross-site query forgery or SQL injection. The use of firewalls is the best solution to fight against these attacks. The unique nature of firewalls means that they should be able to easily recognise fake traffic and act accordingly.
