DDoS Defense Tutorial: Strengthen Your Website Security with CDN and Cloud Services to Ensure Business Stability and Reliability

Release Date: 2023-05-11

DDoS attacks are a type of attack that floods a target website with a large amount of traffic to make it unresponsive to requests. This type of attack has become a major challenge in network security. If you have a website, you need to understand DDoS defense methods to protect your website from attack. In this article, we will introduce the use of CDN and cloud services to protect your website from DDoS attacks.

How CDN Works

CDN (Content Delivery Network) is a distributed network architecture that caches website content on multiple servers, allowing users to access website content from servers closer to them. This improves website performance, reduces network latency, and increases website security.

When you use CDN services, your website content is cached on the servers of the CDN provider. When a user requests to access your website, CDN automatically forwards the request to the nearest CDN server, thereby improving access speed.

Using CDN for DDoS Defense Tutorial

When your website is under DDoS attack, attackers send a large amount of traffic to your website, making it unresponsive to requests. If you use CDN services, CDN can help you filter out this malicious traffic, protecting your website from attack.

CDN can perform DDoS defense in the following ways:

  • User request filtering: CDN can identify and filter out malicious traffic based on IP address, geographic location, and other characteristics of the traffic.
  • Load balancing: CDN can distribute traffic across multiple servers to prevent any one server from being overwhelmed by traffic.
  • Caching: CDN can cache website content on multiple servers, reducing the load on your website server and making it more difficult for attackers to overwhelm it with traffic.

Using Cloud Services for DDoS Defense Tutorial

In addition to CDN, cloud services such as Amazon Web Services (AWS) and Microsoft Azure also provide DDoS defense services.

Cloud service providers can perform DDoS defense in the following ways:

  • Network traffic monitoring: Cloud service providers can monitor network traffic and identify abnormal traffic patterns, such as sudden spikes in traffic volume.
  • Automatic traffic filtering: Cloud service providers can automatically filter out malicious traffic based on predefined rules.
  • Scalable infrastructure: Cloud service providers can scale up infrastructure resources to absorb large amounts of traffic during a DDoS attack.

By using CDN and cloud services for DDoS defense, you can improve the security of your website and ensure that it remains available to users even during a DDoS attack.
