Securing Media Assets in Cloud Storage
A leak of an unreleased commercial is a catastrophic failure. Protecting media assets goes far beyond simply making an S3 bucket private.
Table of contents:
Presigned URLs with Expire Times
Our applications never proxy large video files. Instead, the backend generates short-lived presigned URLs directly to S3, authenticated securely via IAM roles.
VPC Endpoints
We route all traffic between our Lambda functions, EKS cluster, and S3 internally via VPC endpoints, ensuring our media never traverses the public internet.
Watermarking and DRM
For highly sensitive review links, we leverage AWS Elemental MediaPackage to encrypt streams on-the-fly and burn forensic watermarks into the video identifying the viewer.
