The practice of successfully defending a targeted server or network from a distributed denial-of-service (DDoS) assault is known as DDoS mitigation. A targeted victim might lessen the hazard by using specialized network hardware or a cloud-based protection service.

Using a cloud-based service, a DDoS assault can be mitigated in 4 stages:


A website must be able to tell an attack from a large volume of regular traffic in order to halt a dispersed attack. The last thing a website wants to do when a product release or other announcement floods it with genuine new visitors is throttled them or otherwise prevent them from reading the website's content. Proper detection is aided by IP reputation, typical attack behaviors, and prior information.


An efficient DDoS mitigation system will divide the remaining traffic into manageable parts to prevent denial-of-service by intelligently routing traffic.


A good network examines traffic for trends, such as recurrent offensive IP blocks, specific attacks emanating from particular nations, or specific protocols being misused. A protection service can harden itself against upcoming threats by adjusting to attack patterns.


In this step, the DDoS security network reacts to an incoming threat by selectively removing harmful bot traffic while absorbing the remaining traffic. A network can prevent the attempt at disruption by using WAF page rules for application layer (L7) attacks or another filtration mechanism to handle lower level (L3/L4) assaults like Memcached or NTP amplification.

Choosing a DDoS Preventive service

A DDoS attack that is severe enough might destroy the network infrastructure upstream, making any on-site solutions useless. The qualities of a cloud-based DDoS mitigation service should be considered before buying.


A successful solution must be able to expand with a business and respond to DDoS attacks of ever-increasing size. There have been attacks that have exceeded 2 terabits per second (Tbps), and there is no evidence that attack traffic size is on the decline. The network of Cloudflare can withstand DDoS attacks that are much more powerful than those that have ever happened.


DDoS protection is something you only need when you need it, like a seatbelt, but when that time comes it better work. Any protection strategy's success depends on the DDoS solution's dependability. In order to maintain the network operational and be aware of fresh threats, make sure the service has excellent uptime rates and site reliability engineers operating around the clock. An extensive network of data centers, failover, and redundancy should be at the heart of the platform's strategy.

Network size

As specific protocols and attack vectors evolve over time, there are patterns to DDoS attacks that appear on the Internet. A DDoS mitigation service can monitor and respond to attacks rapidly and effectively, frequently halting them before they even happen, thanks to a huge network with lots of data traffic. The network of Cloudflare facilitates Internet requests for millions of websites, giving it a leg up in the analysis of attack traffic data from around the world.


A web property can respond in real-time to new threats by developing ad hoc regulations and routines. A crucial component in maintaining a website online during an assault is the capacity to adopt page rules and populate those changes across the whole network.
