Security Overview
This section covers security principles, features, and best practices for the Arculus Authentication system. Security is organized into application-level security (for developers) and deployment-level security (for infrastructure and DevOps teams).
Overview
The Arculus Authentication system implements security at multiple layers:
Application Security: Input validation, secure coding practices, secure storage, security headers
Deployment Security: Network security, transport security, container security, infrastructure hardening
Defense in Depth: Multiple layers of security controls
Industry Standards: FIDO2/WebAuthn compliance and security best practices
Security Sections
Application-level security measures that developers implement in their code:
Input validation and sanitization
Security headers implementation
CORS configuration
Secure token storage (Android Keystore / iOS Keychain)
Error handling security
Backend-proxied pattern security benefits
Session and cookie security
Multi-tenant security
Audience: Application developers, integration teams
Infrastructure and deployment security measures:
Transport security (TLS/SSL, certificates)
Network security (firewalls, subnets, security groups)
Container security (non-root, minimal images, read-only filesystems)
Secrets management
Infrastructure hardening
Monitoring and logging
Cloud-specific security configurations
Audience: DevOps engineers, infrastructure teams, security administrators
Security Principles
The Arculus Authentication system is designed with security as a fundamental principle:
FIDO2/WebAuthn Compliance: Adherence to industry-standard authentication protocols
Public Key Cryptography: No shared secrets between client and server
Hardware-Based Security: Cryptographic operations performed on secure hardware
Defense in Depth: Multiple layers of security controls
Least Privilege: Minimal access and permissions required
