How does high-defense IP prevent crawlers and web attacks? With the development of the Internet, there are more and more types of network attacks and crawler behaviors. In order to protect the security and stability of the website, many websites use high-defense IP to prevent crawlers and web attacks. So how does high-defense IP prevent crawlers and web attacks? Let’s learn more about it below.
1. Prevent crawlers
A crawler refers to the behavior of automatically accessing a website through a program and obtaining data. Crawlers can consume a website's bandwidth and resources, causing website access to slow down, or even causing the website to crash. High-defense IP prevents crawlers through the following aspects:
(1) IP restriction: High-defense IP can set up a white list and a black list of access IPs, and only allow IPs in the white list to access the website, thus preventing access by illegal crawlers.
(2) Traffic limit: High-defense IP can set traffic limit to limit the number of visits and traffic of the same IP within a unit time, thereby preventing excessive access to the website by crawlers.
(3) Verification code: High-defense IP can set a verification code, requiring users to enter the verification code when accessing the website, thereby preventing automatic access by robots and crawlers.
2. Prevent web attacks
Web attacks refer to the behavior of attacking websites through network attack programs, such as SQL injection, XSS attacks, etc. Web attacks can lead to data leakage, paralysis, and hijacking of websites. High-defense IP prevents web attacks through the following aspects:
(1) DDoS protection: High-defense IP can provide DDoS protection functions. By analyzing and identifying traffic, various types of DDoS attacks can be prevented.
(2) WAF protection: High-defense IP can provide WAF protection function, analyze and identify website requests, and prevent common web attacks such as SQL injection and XSS attacks.
(3) IP restrictions: High Defense IP can set up IP whitelists and blacklists, allowing only IPs in the whitelist to access the website, thereby preventing illegal attackers from accessing.
(4) SSL encryption: High-defense IP can provide SSL encryption function to encrypt the transmission of website and user data, thereby protecting the security of the data.
How does high-defense IP prevent crawlers and web attacks? In summary, high-defense IP is an important technical means to protect the security and stability of the website. It can prevent crawlers and Web through IP restrictions, traffic restrictions, verification codes, DDoS protection, WAF protection, SSL encryption and other methods. attack. When choosing high-defense IP services, you should choose according to your own needs and actual situation to achieve the best results.
