Aligning AWS to MPA security best practices for media archives – Part 1

This article examines how AWS capabilities align with MPA Content Security Best Practices v5.3.1 for securing media archives in the cloud, focusing on foundational security controls.

• AWS shared responsibility model separates infrastructure security (AWS) from workload configuration (customer), with purpose-built services for each area
• AWS ISO/IEC 27001:2022 certification and Config conformance packs support ISMS implementation and compliance requirements
• Mandatory MFA enforcement across all AWS account types addresses authentication requirements for administrative access
• IAM policies with RBAC/ABAC and Identity Center SCIM integration enable least-privilege authorization and automated provisioning/de-provisioning
• Amazon VPC with security groups, network ACLs, and AWS Network Firewall provide network isolation between content and non-content networks
• Default AES-256 encryption in Amazon S3 and TLS 1.2+ enforcement across services meet encryption requirements at rest and in transit

AWS provides a secure-by-default foundation for media archive environments that directly maps to MPA's preventive security controls across organizational, operational, physical, and technical domains.
