How do enterprises choose SSL service providers?

The Internet is enlightened from the internal network of the American military. Because it is a private network, the initial network scale is small and the processing capacity is low. The core of the designed TCP/IP protocol is information transmission, which rarely involves information security. Therefore, the application layer protocols http, smtp and ftp are plaintext data without encryption measures.

With the popularity of the Internet, Internet applications emerge one after another. at the same time, due to the explosive growth of the Internet, the nodes connected to the Internet are full of mud and sand, bringing a variety of Internet threats, how to identify the identity of a website, how to safely transmit confidential or private information, has become a vital issue.

For the vast majority of Internet users, the security and efficiency of the Internet for the protection of customer confidence is far better than the overwhelming advertising. SSL secure socket layer Protocol (secure sockets layer) provides a transport layer secure application protocol to solve the problems of identity identification and encrypted transmission of confidential and private information in Internet service websites. The most important step in the process of SSL deployment is the application and configuration of SSL website Security Certificate (certificate ssl). Deciding which SSL website security certificate to buy is not only a technical issue, but also involves a series of issues such as the company's strategy, service awareness, management and so on. In front of a series of SSL service providers, how should enterprises choose?

There are many important factors for you to weigh when choosing an SSL certificate, the first one is the scope of your business. Many certificates are limited to the number of domains, subdomains and physical servers. It is recommended to fully refer to the parameters provided to select the SSL certificate that is most suitable for your website.

Before you choose, you need to consider whether you need to protect multiple domain names. For example, if you deploy multiple sites with different domain names on one server, it is recommended to purchase SSL multi-domain name certificates. Secondly, multiple subdomains under a primary domain name all need certificates to protect the security of information transmission. You should choose a wildcard certificate. There is no limit to the number of secondary subdomains protected.

For online shoppers, the green address bar is the easiest and most reliable way to verify the identity and security of a website. Under the new generation of high-security browsers such as IE7.0, FireFox3.0, Opera 9.5, the browser address bar of websites using extended authentication (EV) SSL certificates will automatically appear green, thus clearly telling users that the website they are visiting is strictly authenticated. In addition, the area adjacent to the green address bar also displays the name of the site owner and the name of the certification CA authority, such as VeriSign. Everything conveys the same message to the customer, the identity of the website is credible, the transmission of information is secure and reliable, not a phishing site.

It is important to know the encryption length used by the certificate. It takes 4 hours to crack a 40-bit certificate, while it takes more than 1 trillion years to crack a 128-bit certificate. 128-bit mandatory certificate is very popular in the market because it forces consumers to use 128-bit encryption level when they log on to the security page in order to improve security and reduce the possibility of private information leakage to a great extent.

The low-end SSL server certificate is not compatible with most browsers, so it will pop up a security warning or directly prohibit customer access, greatly reducing the success rate of customer login. At the same time, the low-end certificate can not provide 128-bit encryption strength at one time, so there are major hidden dangers in security. For important financial institutions and large shopping websites, the configuration of low-end SSL certificates without authentication is very easy to be fraudulently counterfeited, and its brand value and trust will be seriously tested. The high-end SSl server certificate can be fully compatible with the browser, the high security encryption strength and authentication mechanism can ensure the security and reliability of the website, and its latest EV certificate can display the green address bar to enhance the website security credibility.

In addition, there is a huge gap between free SSL certificates in terms of function, service, certification level, certificate security and certificate application experience. If you only use the free SSL service in the test system, there is no problem, but if it involves private data transmission and online transactions and payments, you should avoid using free SSL certificate products as far as possible, so that the online transmission of confidential data can be better protected.
