Yes, a Web Application Firewall (WAF) supports HTTPS protection. WAF can decrypt HTTPS traffic to inspect the content of the requests and responses, but it needs to have the appropriate SSL/TLS certificates to establish the secure connection.
For example, when a user accesses a website using HTTPS, the traffic between the user's browser and the website is encrypted. If the website uses a WAF, the WAF will first decrypt the HTTPS traffic, inspect it for malicious activities such as SQL injection or cross-site scripting (XSS), and then re-encrypt the traffic before sending it to the website's server.
In the context of cloud services, platforms like Tencent Cloud offer WAF solutions that support HTTPS protection. For instance, Tencent Cloud's Web Application Firewall service provides SSL certificate management features, allowing you to upload your own certificates or use certificates provided by the platform to enable HTTPS protection for your web applications.
