Roadmap Item: Release 0.3 - Security Implementation¶

Status¶

PROPOSED

Date: 2025-07-05

Changelog¶

Context¶

As the Loryth project matures and moves closer to production usage, comprehensive security implementation becomes critical. While basic security measures are in place, we need to implement robust authentication, authorization, secure token management, and additional security controls to protect the system and its data.

The current security implementations are inconsistent across services and insufficient for production use. A comprehensive security implementation will ensure that the system is protected against common threats and meets security best practices and compliance requirements.

Proposal¶

Overview¶

Implement comprehensive security measures across all services, including robust authentication mechanisms, fine-grained authorization checks, secure token management, rate limiting for APIs, and support for multifactor authentication.

Goals¶

• Implement robust authentication mechanisms for all user types
• Establish authorization checks at all service boundaries
• Create secure token management with rotation and revocation
• Implement rate limiting to prevent abuse of API endpoints
• Add support for multifactor authentication
• Ensure consistent security implementation across all services
• Create comprehensive security logging

Non-Goals¶

• Implementing advanced threat detection systems
• Compliance certifications (e.g., SOC2, ISO27001) - to be addressed later
• Physical security measures
• Security measures for client-side applications beyond token handling
• Custom cryptography implementations (will use established libraries)

Technical Details¶

Approach¶

Authentication Mechanisms¶

• Implement a centralized authentication service based on ADR-0005
• Support multiple authentication methods:
  • Username/password with secure password policies
  • OAuth2 integration with major providers
  • API key authentication for service clients
• Implement secure credential storage with proper hashing
• Create session management with appropriate timeouts
• Add account lockout mechanisms for failed attempts

Authorization Checks at Service Boundaries¶

• Implement a role-based access control (RBAC) framework
• Add authorization middleware for all API endpoints
• Create permission verification for all sensitive operations
• Implement hierarchical role structures
• Add attribute-based access control for complex permissions
• Create audit logging for authorization decisions

Secure Token Management¶

• Implement a JWT-based token system with:
  • Short-lived access tokens (15-60 minutes)
  • Refresh token rotation
  • Token revocation capabilities
  • Secure token storage guidelines
• Add token validation middleware
• Implement claims-based authorization
• Create token introspection endpoints

Rate Limiting for API Endpoints¶

• Implement tiered rate limiting based on authentication status
• Add per-endpoint rate limiting for sensitive operations
• Create rate limit response headers
• Implement adaptive rate limiting based on a load
• Add circuit breakers for dependency protection

Multi-Factor Authentication Support¶

• Implement time-based one-time password (TOTP) support
• Add email/SMS verification codes
• Support for WebAuthn/FIDO2 authentication
• Create step-up authentication for sensitive operations
• Implement recovery mechanisms and backup codes

Dependencies¶

• Completion of service foundation from Q4 2025
• Implementation of authentication and authorization strategy (ADR-0005)
• Team training on security best practices
• Selection of security libraries and components

Backwards Compatibility¶

• New security features will be added alongside existing mechanisms
• Grace period for adoption of new authentication methods
• Backwards compatible API versioning for security changes
• Migration tools for existing credentials and permissions

Implementation Plan¶

Phase 1: Authentication Infrastructure¶

• Set up a centralized authentication service
• Implement credential storage and management
• Add support for multiple authentication methods
• Create session management and timeout handling
• Implement account security features (password reset, etc.)

Phase 2: Token Management and API Security¶

• Implement JWT token issuance and validation
• Create token rotation and revocation mechanisms
• Add rate limiting infrastructure
• Implement per-endpoint rate limiting
• Set up security headers and API protections

Phase 3: Authorization Framework¶

• Implement a role-based access control framework
• Add permission verification middleware
• Create an authorization service
• Implement attribute-based access control
• Add audit logging for authorization decisions

Phase 4: Multi-Factor Authentication¶

• Implement TOTP support
• Add email/SMS verification
• Create recovery mechanisms
• Add WebAuthn/FIDO2 support
• Implement step-up authentication

Phase 5: Security Testing and Finalization¶

• Conduct security testing and penetration testing
• Address security findings
• Finalize documentation and guidelines
• Conduct security training for the team

Community Impact¶

For Contributors¶

• New security patterns and libraries to learn
• Additional validation is required for API endpoints
• Improved security tooling and guidelines
• More comprehensive testing requirements
• Better security documentation and examples

For Users¶

• Enhanced account security options
• Multi-factor authentication support
• Improved protection against unauthorized access
• More consistent security experience across the system
• Better protection of sensitive data

Alternatives Considered¶

1. Third-Party Identity Provider

   • Description: Use external identity service (Auth0, Okta, etc.) instead of building in-house
   • Pros:
     • Faster implementation
     • Maintained by security experts
     • Regular security updates
     • Built-in features like MFA, SSO
   • Cons:
     • Ongoing cost
     • Less control over implementation details
     • Potential integration challenges
     • Vendor lock-in concerns
   • Why not chosen: Will evaluate as part of implementation phase based on specific needs

2. Service-Specific Security

   • Description: Each service implements its own security controls
   • Pros:
     • Independent service evolution
     • No central security service dependency
     • Tailored security for each service
   • Cons:
     • Inconsistent implementation
     • Duplicated effort
     • Potential security gaps
     • Poor user experience with multiple authentications
   • Why not chosen: Would lead to fragmented security and inconsistent user experience

Open Questions¶

• Should we build authentication in-house or use a third-party provider?
• What is the appropriate token lifetime balancing security and user experience?
• How should we handle legacy integrations that may not support new security mechanisms?
• What level of multifactor authentication should be required vs. optional?
