Security Architecture Specification
Overview
Security architecture including threat model, security boundaries, and security controls.
Threat Model
Threat Categories
1. External Threats:
- DDoS attacks
- SQL injection
- XSS attacks
- API abuse
2. Internal Threats:
- Privileged user abuse
- Data breaches
- Insider threats
3. Infrastructure Threats:
- Node compromise
- Database breaches
- Network attacks
Security Boundaries
DMZ: Public-facing services Internal Network: Backend services Data Layer: Database and storage (isolated) Blockchain Network: Node network (isolated)
KMS/HSM Integration
Key Management
Storage: Hardware Security Module (HSM) Usage: API keys, signing keys, encryption keys Access: Role-based, audit logged
Secrets Management
Secret Storage
Solution: Vault, AWS Secrets Manager, or similar Encryption: At rest and in transit Rotation: Regular key rotation Access: Least privilege principle
Signed Builds and SBOM
Build Signing
Process: Sign all builds Verification: Verify signatures before deployment Tooling: Code signing certificates
SBOM (Software Bill of Materials)
Generation: Generate SBOM for all dependencies Storage: Store SBOM for audit Vulnerability Scanning: Scan SBOM for known vulnerabilities
