Security
Security principles, auditability measures, and governance controls designed into Syzygy Rosetta.
Security Principles
Rosetta is designed from the ground up with security and trust as foundational requirements. The following principles guide our approach:
Auditability
Every action within the system produces a verifiable record. Nothing happens without leaving evidence.
Traceability
Every decision can be traced back through the complete chain of evaluation, from application through model through human review.
Policy Enforcement
All decisions are evaluated against defined policies before finalization. Policies are versioned and auditable.
Governance Controls
Role-based access controls, separation of duties, and approval workflows ensure proper oversight.
Evidence Preservation
Audit receipts are cryptographically sealed and stored in tamper-evident chains. Historical evidence cannot be modified.
Independent Verification
Evidence records can be independently verified by third parties without access to the originating system.
Evidence Integrity
The integrity of audit evidence is the foundation of the Rosetta value proposition. We are designing for:
- Cryptographic sealing of every audit receipt at creation time.
- Chain-based integrity where each receipt references the cryptographic hash of the previous receipt.
- Independent verification capabilities that do not require access to the originating Rosetta instance.
- Tamper detection that makes any modification to a receipt immediately detectable.
- Immutable storage that preserves the complete history of all receipts.
Access Controls
Rosetta is designed to support granular access controls that enable financial institutions to enforce the principle of least privilege:
Role-Based Access
Different roles (compliance, audit, engineering, management) have different levels of access.
Separation of Duties
No single role has end-to-end control. Policy changes, for example, require approval.
Access Logging
All access to evidence records is itself logged for audit purposes.
Development Status
The security architecture, cryptographic implementations, and access control mechanisms described here represent our design goals and planned approach. Specific security controls, encryption standards, and verification mechanisms may evolve during development. We recommend consulting with your security and compliance teams to evaluate Rosetta against your specific requirements when it becomes available.
