🔐 Security Principles

The Stellar Teye platform is built on these core security principles:

  1. Defense in Depth - Multiple layers of security controls
  2. Zero Trust - Never trust, always verify
  3. Least Privilege - Minimum necessary permissions
  4. Fail Secure - Default to secure state
  5. Transparency - Open security design and auditability

🛡️ Security Architecture Overview

Core Security Components

  • Identity & Authentication: Multi-factor authentication with progressive authorization
  • Access Control: Role-based access control (RBAC) with admin tiers
  • Data Protection: End-to-end encryption with zero-knowledge proofs
  • Audit Trail: Immutable on-chain audit logging
  • Rate Limiting: DoS protection and abuse prevention
  • Compliance: HIPAA-aligned security controls
