Yes, a Cloud Firewall can protect CDN (Content Delivery Network) and COS (Cloud Object Storage).

A Cloud Firewall acts as a security layer that monitors and controls incoming and outgoing traffic based on predefined rules. It can safeguard CDN and COS by blocking malicious requests, DDoS attacks, and unauthorized access. For example:

  • CDN Protection: A Cloud Firewall can filter harmful traffic before it reaches the CDN edge nodes, preventing attacks like SQL injection or cross-site scripting (XSS) from affecting cached content.
  • COS Protection: It can restrict access to COS buckets by allowing only trusted IP ranges or requiring authentication, reducing the risk of data breaches.

In Tencent Cloud, services like Web Application Firewall (WAF) and Security Group can be integrated to enhance protection for CDN and COS. For instance, WAF can filter malicious traffic targeting CDN endpoints, while Security Groups can control access to COS buckets at the network level.
