Now, more and more websites begin to apply for SSL certificates to protect users' privacy and data security, while the emergence of free SSL certificates makes many website operators laugh to themselves. But is this kind of white whoring without paying any price really taking advantage? Micronet believes that this is not the case, which is not of any substantive help to the website, but is prone to hacker intrusion.
The freely used SSL certificate usually automatically matches the information of the applicant or organization and the domain name information through the program. As long as the match is consistent, the certificate can be obtained without manual review. This certificate can only verify the ownership of the domain name, not the organization, that is, the identity of the server, so it leaves a large security vulnerability and hidden danger.
By simply verifying the domain name information, hackers can easily obtain certificates, thus putting on a layer of credibility for themselves. At this moment, https can still play the role of encrypted transmission, but the purpose of information transmission has changed from a real website server to a hacker's "phishing" server. Information encryption is also like the emperor's new clothes, and hackers can easily seize users' sensitive information.
In addition to the risk of hackers "phishing", the free SSL certificate is subject to many use restrictions. For example, free certificates can only be bound to one domain name and do not support wildcard domain names. Similarly, such "free lunch" related services will also be greatly discounted. Most of the free SSL certificates are installed by users themselves, unable to provide post service and technical support, and can not be solved in time when the certificate encounters problems. In addition, the validity period of some brands' free SSL certificates is too short. They are renewed every three months. After expiration, they have to apply for their own certificates. Many users easily forget to renew them.
Therefore, in the case that the current free certificate authentication mechanism is not perfect, Huawei Cloud recommends that you avoid using free SSL certificates for the security of users and websites, especially for large enterprise or institutional websites. For e-commerce platforms involving user privacy and financial transactions, you should not choose "free lunch".
If the website has installed an OV or EV type SSL certificate, click the lock icon in the address bar, and the DigiCert authentication website identity will be displayed, indicating that the website certificate is authentic and reliable, and the identity is authentic and reliable. Huawei Cloud is an excellent cloud computing operator in China. It can provide one-stop certificate issuing service, which is professional and secure.
