How to choose when a website encounters CC attack, firewall or CC defense server? Among them, the common CC attack (Challenge Collapsar) is also a kind of DDOS (distributed denial of service), and it is also a common website attack method. The attacker continuously sends a large number of data packets to the victim host through a proxy server or a zombie, causing the other party's server resources to be exhausted until it crashes.
　　CC attack has low technical content. Using tools and some IP proxies, a beginner or intermediate computer user can carry out the attack. However, if you understand the principle of CC attack, it is not difficult to implement some effective preventive measures against CC attack.
　　1. What are the ways to defend against CC attack?
　　There are several ways to prevent CC attack. One is through a firewall. Some network companies also provide some anti-CC attack servers, such as the anti-CC server and XX guard of the JTTI website. Another method is to write a program to prevent it yourself. Yesterday, the website encountered a CC attack, which also made me try the effectiveness of various methods to prevent CC attacks. Among them, CC high-defense server is the most successful security measure.
　　At first, I wanted to use a certain website guard to prevent attacks. From the interface, it seemed that a large number of CC attacks were prevented, but after logging into the website, I found that the traffic was still abnormal and the attacks were still there. It seemed that the effect of this website guard was not achieved.
　　In principle, basically all firewalls will detect the number of concurrent TCP/IP connections. If it exceeds a certain number and frequency, it will be considered as Connection-Flood. But if the number of IPs is large enough, so that the number of connections of a single IP is small, then the firewall may not be able to prevent CC attacks.
　　In fact, by analyzing the website log, it is still very easy to distinguish which IP is CC attack, because CC attack is to crawl web pages through programs after all, which is very different from the characteristics of ordinary browsers. For example, when ordinary browsers visit a web page, they will definitely crawl a series of related files such as HTML files, CSS files, JS files and pictures of the web page continuously, while CC attackers will only crawl files with a URL address, and will not crawl other types of files. Their User Agents are also mostly different from ordinary browsers. This makes it easy to distinguish which visitors are CC attacks on the server. Since the attacker's IP can be determined, the preventive measures are very simple. You only need to block these IPs in batches to achieve the purpose of preventing CC attacks.
　　2. How to use CC high-defense server to defend against CC attacks?
　　1. What is CC high-defense server?
　　CC high-defense is a solution for DDoS attacks. DDoS attack refers to flooding the target server with a large number of malicious requests, making it unable to operate normally. CC high-defense maintenance guides normal user traffic to the target server by intelligently identifying and filtering malicious traffic, thereby ensuring normal access to the website.  
　　2. Why choose CC high-defense server?
　　CC high-defense has powerful attack interception capabilities. It can quickly identify malicious requests based on real-time traffic monitoring and analysis, and intercept them outside. In this way, even if it suffers a large-scale DDoS attack, it can effectively ensure the stable operation of the website.
　　CC high-defense also has the ability of intelligent learning and adaptive defense. It can learn according to the attacker's attack methods and strategies, and adjust the defense strategy in real time. This intelligent defense method enables CC high-defense maintenance to cope with various new attack methods and maintain continuous and effective protection.
　　Compared with the defense of other software, JTTI CC high-defense server has the advantage of intelligent defense, does not affect the access of normal users, and also provides round-the-clock technical support. Whether it is during an attack or at ordinary times, users can contact a professional team for help at any time. In this way, even if they encounter network security problems, users can get timely solutions.
　　3. How to choose a suitable CC high-defense maintenance service?
　　The first thing to consider is the reputation and strength of the service provider. Choosing a service provider with rich experience and strong technology can better ensure the security of the website.
　　Secondly, consider whether the products and services provided by the service provider meet your needs. Different websites may face attacks of different types and scales, so you need to choose the corresponding CC high-defense maintenance plan according to your own situation.
　　Price factors should be considered. Although network security is very important, the cost issue cannot be ignored. Choosing a cost-effective CC high-defense maintenance service can reduce costs while ensuring security.
　　CC high-defense server is one of the important means to protect website security. It builds a solid line of defense for websites and servers by intelligently identifying and filtering malicious traffic. Choosing a suitable CC high-defense maintenance service provider and customizing the configuration according to your own needs can better ensure the normal operation of the website. Let us strengthen network security awareness and jointly build a more secure and reliable network environment.
