All security-related TypeScript interfaces are defined in src/types/security.ts:

Defense in Depth: Multiple layers of authentication and data protection
Principle of Least Privilege: Authentication only when necessary
Client-Side Security: All sensitive operations and data handling occurs locally on the device
Zero Trust Architecture: Every request is authenticated and authorized properly
Privacy by Design: Wallet addresses and sensitive data are properly anonymized
Secure by Default: Security features are enabled by default
