(DRAFT) SVTA5062: OTT Streaming CDN Security Best Practices
A Content Delivery Network (CDN) is a distributed network of servers used for the delivery of assets to consumer devices. In the context of streaming services, CDNs are responsible for delivering manifest files, media content, and static files efficiently. CDNs are designed to handle the high-volume streaming of these assets across extensive geographic areas. A range of documentation is available on-line to guide OTT (Over-The-Top) streaming operators in optimizing their CDNs for enhanced content delivery to users. This involves minimizing startup delays, rebuffering events and efficiently managing operational expenses. However, limited information is available for streaming operators wishing to protect their assets and CDN from abuse. This document provides descriptions of some of the known attacks of today and best practice guidance for OTT streaming services to secure their CDN and assets.
Goals and Objectives
- Provide an overview of contemporary piracy attacks and how they can impact operational efficiency and distribution expenses.
- Document the best practices to improve security of the CDN for streaming applications.
- Describe methods for ensuring the security of the playback and DRM license requests.
