Security Architecture

Security Overview​

The platform implements a comprehensive security model with multiple layers of protection:

  1. Authentication & Authorization

    • JWT-based authentication with refresh token rotation
    • Role-based access control (RBAC) for granular permissions
    • Session management with secure timeout mechanisms

  2. Data Protection

    • End-to-end encryption for sensitive communications
    • Data encryption at rest using AES-256
    • Transport layer security (TLS/SSL) for all connections

  3. Infrastructure Security

    • Cloud provider security configurations
    • Network isolation and firewall rules
    • Regular security audits and penetration testing

  4. Smart Contract Security

    • Formal verification of critical contract logic
    • Explicit permission checks in all state-changing functions
    • Rate limiting for sensitive operations

Security Principles​

The platform adheres to the following security principles:

  • Defense in Depth: Multiple security controls at different layers
  • Principle of Least Privilege: Minimum required permissions for each role
  • Secure by Default: Conservative security settings as default
  • Fail Securely: Errors default to denying access rather than granting it
  • Complete Mediation: Every access to resources is checked for authorization
  • Separation of Duties: Critical operations require multiple approvals
