Protection Against DDos Attacks

One difficulty with DDoS assaults is that they might be difficult to protect against using typical means. Filtering out fraudulent traffic without impacting genuine users may be difficult for businesses. Companies have frequently had little choice but to ride out attacks in the past. So the question is how does a CDN helps in protection against DDos attacks?

However, there are now additional techniques available to combat this issue, including the usage of a content delivery network, which is a popular alternative (CDN). This works by dividing your traffic among a number of servers located all around the world.

They have a number of advantages, including increased dependability and the ability to provide a seamless, quick experience to clients from all over the world. However, they can also protect against DDoS assaults.

CDNs are built to manage massive volumes of traffic, so if a firm suffers a spike in traffic, such as that caused by a DDoS assault, it can respond by redistributing the traffic and ensuring that it does not reach your origin servers.

  • Customers will be able to visit your website as usual, and they will be unaware that you are under assault.

  • DDoS attacks have become a common approach for fraudsters to target your website. It’s simple to understand why.

First and foremost, it does not need any hacking abilities. The goal of a DDoS attack is to flood your website with traffic. A cybercriminal may buy a botnet for a few bucks and use it to send a flood of traffic to your site, slowing it down or making it unreachable entirely.

Second, DDoS assaults are frequently employed in conjunction with other types of cyberattacks. DDoS assaults operate as a deterrent while a more dangerous attack, such as SQL injection, is carried out against your website.

SQL injection is a type of attack in which malicious SQL statements are inserted into a database entry and then executed. It enables fraudsters to impersonate you, tamper with your data, and commit other crimes such as cancelling transactions or altering account balances.

CDNs, fortunately, can provide extra security against DDoS assaults in an unexpected way. Let’s learn more about how to secure a content delivery network.

What exactly is a CDN (Content Delivery Network)?

Protect website from DDos Attacks

A content delivery network, or CDN, is a system or network of geographically distributed servers that transport online content from the origin server to end-users anywhere on the planet.

It accomplishes this by saving a cached or duplicated version of your website’s web page, complete with HTML, CSS, Javascript, images, and videos.

A request is made from the user’s computer or mobile device when a website visitor wishes to view a certain online page. All requests will be forwarded to the origin server if there isn’t a CDN in place. High traffic volumes, even without a DDoS assault, might overload the origin server, causing it to crash or fail. For cybercriminals, this is why DDoS assaults are so useful.

CDNs, thankfully, take the pressure off the origin servers. A web page request is optimally mapped and forwarded to the closest CDN server when it is made. The cached version of the web page will be delivered to the visitor’s device by this server in response to the request.

Even if they are not in close proximity to the origin server, online users benefit from this procedure since their web pages load quickly.

How CDNs Help Prevent DDoS Attacks on Your Website

Protect website with CDN from DDos attacks

While content delivery network solutions and services are commonly linked with enhancing online performance and page load rates, they also aid in the protection of websites, particularly against DDoS attacks.

Modern CDN providers have incorporated advanced security features to their servers to defend them from DDoS assaults.

CDNs have a variety of characteristics that make them an effective approach to protect your website against DDoS assaults, including:

Large Capacity to Handle High Traffic Volumes

CDN systems are designed from the ground up to evaluate and manage unusually high volumes of traffic to a website. High traffic spikes owing to natural occurrences such as marketing, sales, and SEO initiatives are examples of this. This capacity to manage large amounts of bandwidth is also essential in dealing with unusually large amounts of traffic caused by DDoS assaults.

Cloud CDN solutions’ IT infrastructure is capable of absorbing even the most powerful low-level DDoS assaults without breaking a sweat, thanks to its vast capacity.

Cleansing and Monitoring Tools that are Proactive

Of course, merely being able to absorb large amounts of traffic is insufficient. As a result, the best CDN providers have a wide range of solutions to protect websites from all types of assaults. These technologies are capable of proactive monitoring for potential assaults as well as traffic inspection and cleaning for unnatural and destructive visits.

All 5 TLS extensions are supported

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