Data Security Architecture

About The Standard Domain

The Data Security Architecture domain defines how organizations classify, protect, manage, and govern data throughout its lifecycle.

It provides architectural expectations for secure storage, controlled access, secure exchange, resilient recovery, retention practices, and traceable governance controls needed to protect sensitive information and maintain operational trust.

Data Classification

Secure Storage

Controlled Access

Protection & Recovery

Governance & Traceability

Why Adoption is Necessary

Architectural Clarity

Provides a clear blueprint for protecting data across systems, applications, repositories, and exchanges.

Consistent Engineering Expectations

Aligns teams on secure handling, storage, sharing, retention, disposal, and recovery of sensitive data.

Measurable Verification

Supports validation of data protection controls, lifecycle practices, access decisions, and resilience outcomes.

Stronger Evidence

Improves traceability and defensible evidence for data security design, implementation, control operation, and review.

How The Standard Works

Requirements

Define the outcomes and capabilities data architectures must achieve to protect information effectively.

Technical Specifications

Provide the architectural patterns, protection methods, and control expectations needed to meet the requirements.

Verification and Validation

Define how to test, verify, and validate that data protection controls and recovery measures operate as intended.

Implementation Guidance

Offer practical guidance, patterns, and best practices to implement the standard effectively across real environments.

Associate Standards Coming in Q3 2026

Detailed, implementation-level standards that support D01 will be published in Q3 2026 to help teams operationalize secure network architectures.

Built for Builders. Backed by Evidence.

D05 provides the architectural foundation for secure data environments, designed, engineered, and proven to protect information across storage, use, sharing, retention, recovery, and governance.
