When you launch your online business and implement monetization strategies, it is very important to protect your assets from viral distribution. SpaceCDN allows content providers to specify content protection rules enforced by content delivery network (CDN).
With SpaceCDN CDN solutions, end visitors can access the media through the workflow specified by publisher. Website data protection allows developers to set limits on content access on the CDN network with the help of different methods. Initially, default permissions on CDN content are taken from the parent folder, e.g. if you apply protection policy to root content folders, it will be automatically applied to all files in the subfolders. Multiple security rules will apply to folder’s contents at the same time to ensure additional protection.
The most common way of content protection is URL signing. CDN account owner may use this service to publish content with a query string parameter token that features URL expiration timestamp. The token is generated by user’s origin server and can be used for making unique publishing URLs for every end user request. With URL signing free distribution of content outside the workflow is prevented the following way:
- If a visitor tampers with the URL, the request for the content in CDN system will be denied.
- If formatted URL has timestamp expired, end users’ requests for CDN content will be denied.
Other popular content protection policies may include Basic Authentication, URL Signature Parameter and Expiration Parameter. Time to live (TTL) helps to renew files stored in cache by purging them. Geographic restriction prohibits access for visitors from some certain regions specified by the user.
