1.Abstract
To tackle the increasingly severe cybersecurity challenges, more and more websites are opting for High Defense CDNs to enhance protection, especially when facing DDoS and CC attacks. You may have heard of these attacks, but how exactly does a High Defense CDN safeguard websites in the face of such complex threats? Let’s explore its powerful capabilities.
2.The Nemesis of DDoS Attacks
DDoS (Distributed Denial of Service) attacks are one of the most common methods used by hackers, flooding target servers with a constant stream of malicious traffic, causing them to crash. Imagine your website under such an attack, where the server cannot handle the load and crashes, making your site inaccessible to visitors.
The working principle of High Defense CDN lies in hiding your server's IP address. All traffic is routed to CDN nodes, which are distributed across multiple locations. These nodes employ high-defense performance servers to spread the attack traffic. Attackers find it difficult to target a single node because these nodes are widely and randomly distributed. As a result, even if attackers launch large-scale traffic attacks, the impact is greatly reduced, protecting your server from being affected.
3.Effectively Defending Against CC Attacks
If you think DDoS attacks are bad enough, CC (Challenge Collapsar) attacks may be even more frightening. Unlike DDoS, CC attacks simulate legitimate user requests, sending massive numbers of requests to exhaust the target server's computational and bandwidth resources. This process is quite stealthy and cannot be defended by ordinary firewalls or simple traffic control methods. Eventually, the server may slow down drastically or even crash due to an overload of requests.
High Defense CDN performs exceptionally well when facing CC attacks. It uses intelligent verification systems that can quickly distinguish between normal user requests and malicious attackers. Through smart algorithms, the CDN automatically blocks fake requests, allowing only legitimate traffic to continue to your website. This way, malicious traffic is effectively intercepted, and legitimate users can access your website smoothly, while attackers are left without a way to proceed.
4.Limitations of Regular CDN
While regular CDNs do have some defense capabilities, especially in hiding the real IP address, they have a significant drawback: when facing large-scale traffic attacks, CDN services can be "abused." Attackers can generate a large number of invalid requests, consuming the server’s bandwidth, leading to unnecessary high bills. This is particularly burdensome for website owners when traffic increases significantly.
In contrast, High Defense CDN excels in this area. It not only prevents malicious traffic from overloading the server through efficient traffic monitoring and distribution mechanisms but also adjusts defense strategies flexibly to avoid excessively high costs caused by large volumes of invalid traffic. The high-intelligence defense system of High Defense CDN significantly reduces the risk of traffic abuse while ensuring a seamless user experience.
5.Defense Strategies of High Defense CDN
Different websites and businesses face different security threats, so defense strategies must be tailored to the specific situation. One of the key features of High Defense CDN is its high degree of customization. You can choose different defense modes and strategies based on your needs, with varying levels of protection to counter different scales and types of attacks. For example, if your site is facing a highly targeted attack, the CDN can rigorously filter traffic from specific sources. On the other hand, if your site is under a large-scale DDoS attack, the CDN can efficiently absorb traffic pressure, ensuring stable operation of your site.
6.Conclusion
In summary, High Defense CDN not only helps to hide real IP addresses and effectively defend against DDoS and CC attacks but also provides comprehensive protection through advanced technologies, ensuring secure business operations. If you are looking for an efficient and reliable defense solution for your website, High Defense CDN is undoubtedly a worthy choice.
