What is DDoS Mitigation/Protection?

DDoS mitigation, more commonly known as DDoS Protection, is the process where a targeted network or server is successfully protected against an attack from distributed denial-of-service (DDoS). This is done by utilizing a cloud-based protection service or specially designed network equipment that mitigates the incoming threat towards the targeted network or server.

The stages of DDoS mitigation

The 4 stages of DDoS mitigation utilizing a cloud-based provider are:

Detection

To be able to prevent a distributed attack, the website is needed to distinguish the attack from a higher volume of web traffic. For instance, if there were to be a product release or any other important announcement on your website, it is likely for it to receive a massive lot of new visitors, and the last thing you want then is to throttle down or stop the visitors from viewing the content of your website. What help most in detection are:

· Common attack patterns

· IP reputation and

· Previous data assists.

Response

Critical for DDoS mitigation, the DDoS protection network intelligently responds to the incoming threat by dropping malicious bot traffic that absorbs the remaining traffic. Utilizing the WAF page rules for attacks on the application layer (L7), or any another filtration process that handles lower level (L3/L4) attacks like the NTP amplification or Memcached, a network is then able to mitigate the attempts made at disruption.

Routing

The intelligent routing of traffic enables effective DDoS mitigation as it breaks the rest of the traffic into more manageable chunks. Thus, preventing denial-of-service.

Adaptation

An effective and capable network analyses the traffic patterns like the repetitive offending IP blocks, improper use of specific protocols, or even particular attacks made from a certain country or countries. By adapting to patterns like these, a protection service can secure itself against similar attacks in the future.

How to choose a DDoS mitigation service?

A traditional DDoS mitigation solution involves the purchase of equipment that lives on the site and ensures the filtration of incoming traffic. However, this approach involves purchasing and maintaining expensive equipment. It is also dependant on having a network that was capable of absorbing such an attack.

If you are looking to purchase a cloud-based DDoS mitigation service, then you must evaluate certain characteristics. Some of them being:

Scalability

If your business is growing, then you should look for an effective solution that can adapt well to the growing needs of your business and even the respond better to the growing size of DDoS attacks.

Flexibility

The ability to create ad hoc patterns and policies allow the web property to adapt to all the incoming threats in real-time. To be able to implement the page rules and populate these changes throughout the network is imperative to keeping a site online when under an attack.

Reliability

DDoS protection is something that is only needed at the time. To exemplify that, think of it like a seatbelt which isn’t needed often, but when needed, it better be functional! Hence, the reliability of DDoS protection solutions is of utmost importance for it to succeed in protecting a server. When purchasing one, make sure that the DDoS solution has a high uptime rate and good site reliability engineers that work 24/7 to ensure the network stays online and never misses identifying new threats.

Network size

A large network with an extensive data transfer enables a DDoS mitigation provider to analyse and respond quicker and more efficiently to attacks made on the server, often stopping the attacks even before their occurrence.

Hopefully, with this information, you will be better equipped to purchase a DDoS mitigation service for your business.
