This article introduces you how to build a firewall with SSL certificate, the content is very detailed, interested friends can use it for reference, I hope it can be helpful to you.

With the development of our Internet technology, this is also a very convenient way for hackers to steal property. Therefore, we all need to protect the security of data transmission, so that users can safely browse our website, which is also respect for users, so as to get the support of users. If a website can not guarantee the security of its own website, it will not be trusted by users. There are many ways to protect users' private information on corporate websites, among which the installation of SSL certificate is one of the most effective ways to improve the security of websites. If the website obtains the SSL certificate, it must provide the authoritative certificate issuer with relevant real materials for SSL certification. The real website which has been thoroughly verified is qualified to obtain the SSL certificate. Due to the strictness of the audit, hackers and phishing sites cannot obtain SSL certificates. At the same time, the uniqueness of the SSL certificate can not be imitated by phishing sites. So SSL can protect the website to build a good reputation and prevent users from falling into phishing sites.

In addition, as a security layer, SSL certificates encrypt information. Even if hackers can intercept relevant information, the content of the information is meaningless to them. Because the encrypted information will be a randomly scattered combination of strings, it is difficult to identify. At the same time, because the encryption strength of SSL certificate is relatively long, the encryption strength above 128 has not been cracked.

Three functions of SSL certificate.

First, data confidentiality. During transmission, make sure that the content is not seen by a third party.

Second, data integrity. Real-time detection that the transmitted content has been tampered with by a third party.

Third, identity authentication. Authenticate the real identity of the website server to ensure that the data reaches the desired destination.

HTTPS's trust is based on a certificate authority pre-installed in the browser, or CA for short. By default, browsers will have some root certificates of CA institutions built in, and only certificates issued by trusted CA institutions can be trusted.

What are the benefits of deploying SSL certificates?

① improves site search rankings: HTTPS sites rank better in search engines. Both Google and Baidu have made it clear that priority is given to HTTPS sites.

B conforms to the PCIDSS specification: SSL is an important part of the PCI specification.

③ conforms to the national information security level protection: Isobao 2.0 puts forward higher requirements for the use of cryptographic technology, communication transmission should use cryptographic technology to ensure the confidentiality of sensitive information paragraphs and the whole newspaper in the communication process, open HTTPS protocol, and transmit identification information in these encrypted ways.

④ meets iOSATS requirements: in order to promote HTTPS, Apple also announced on WWDC2017 that new apps must turn on APS (AppTransportSecurity) security features.

⑤ higher security: HTTPS website can prevent user names, passwords, transactions, residential information and other private information from being stolen and modified, and ultimately ensure the security of website data transmission. After installing the SSL certificate, the browser has a built-in security mechanism to check the status of the certificate in real time and show the authentication information of the website to the user through the browser. Users can simply verify the real identity of the website, prevent intermediary hijacking, identify fraudulent, phishing and other fake websites.

⑥ enhances the company's brand image and credibility: if you install a SSL certificate, the browser will appear secure (or small lock pattern), and an unsafe prompt will appear on the website without the SSL certificate.

About the SSL certificate how to build a firewall to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
