How to fight a DDoS attack

Any entity connected to the Internet is a target for cybercriminals who can use Distributed Denial of Service (DDoS) attacks to reach it. This will result in an interruption of the services provided and therefore financial losses, not to mention that it will tarnish the image of the target. How to fight against a DDoS attack? Find out the answer in this article.

Recourse to the protection offered by hosting providers?

Some hosting providers like this URL make protection against DDoS attacks available to their customers. Different levels of protection are usually provided some as effective as others. And a default protection is sometimes included in the hosting plan. In the latter case, it is necessary to make sure of the level of protection offered. Indeed, the filtering implemented often has limits. Generally, these proposals do not allow to define specific filtering rules or to benefit from an effective protection in case of an attack.The possibilities to make adjustments are sometimes only accessible through additional options. go to https://www.erowz.no for more information.

Equipping with firewalls

Firewalls and load balancers can help absorb some DDoS attacks, such as those with relatively low traffic. In any case, you can use the firewall to filter traffic based on the transport protocol and source port, and can even limit the number of requests to the server from each source IP address.

A quick reminder of what a DDoS attack is

Denial of service attacks are designed to make one or more services unavailable. Denial of service can include the exploitation of software or hardware vulnerabilities, for example. Service disruptions can also be achieved by preventing access to that service, for example by saturating network bandwidth: these are called capacity attacks. In addition, an attack may require one or more service resources until they are exhausted. For example, this could be a large number of new TCP sessions opened in a short period of time, or even too much simultaneous processing by the database.
