Increased Security with CDN

DDoS attacks have grown in popularity as a method for cybercriminals to launch an attack against your website. They don’t require any hacking skills and are all about flooding your website with traffic. A cybercriminal can purchase a botnet for a few dollars and launch a massive amount of traffic to your site with the intent of slowing it down or rendering it inaccessible entirely. Another reason for their popularity is that they are usually used with another cyberattack. DDoS attacks serve as a decoy while a more dangerous attack, such as SQL injection, is launched against your website. SQL injection is an attack in which malicious SQL statements are inserted into a database entry for execution. It enables cybercriminals to impersonate others.

What exactly is a CDN?

The term “content delivery network” (CDN) refers to a system or network of geographically distributed servers worldwide that aims to deliver web content from the origin server to end-users from anywhere in the world. It accomplishes this by storing a cached or copied version of your website’s web page, including the elements required to load, such as HTML, CSS, Javascript, images, and videos.
When a website visitor wants to view a specific web page, a request is sent from the user’s computer or mobile device. All submissions will be routed to the origin server if a CDN is not used. Even in the absence of a DDoS attack, high traffic volume can overwhelm the origin server, resulting in a server crash.

This ability to handle high traffic volumes is also helpful in dealing with unusually high volumes of traffic caused by DDoS attacks. The sheer capacity of cloud CDN solutions’ IT infrastructure can absorb the most potent low-level DDoS attacks.

Tools for Proactive Monitoring and Cleaning

Of course, simply absorbing high volumes of traffic will not suffice. As a result, top CDN operators have various tools to protect websites from multiple types of attacks. These tools are capable of proactive monitoring for potential attacks and inspection and cleansing of traffic for unnatural and harmful visits.

All five major TLS extensions are supported.

TLS, or Transport Layer Security, is a protocol that provides authentication, privacy, and data integrity between the origin server and the CDN server and then between the CDN server and the end-user.

Green Plus CDN, as one of the leading CDN platform providers, supports all five major TLS extensions, including HTTP/2, OCSP Stapling, Dynamic record sizing, ALPN, and Perfect forward secrecy.
