Security Architecture

This section covers security architecture patterns and design principles for building secure, resilient systems.

Topics Covered

🛡️ Web Security Patterns

• Web Application Firewalls - Layer 7 protection for web applications

Coming Soon

🔐 Authentication & Authorization Patterns

• Zero Trust Architecture - Never trust, always verify principles

• OAuth 2.0 & OpenID Connect - Modern authentication and authorization

• JWT Implementation Patterns - Token-based authentication strategies

• Multi-Factor Authentication (MFA) - Enhanced security layers

• Single Sign-On (SSO) - Unified authentication across services

🏛️ Identity Management Patterns

• Identity Provider (IdP) Patterns - Centralized identity management

• Federation Patterns - Cross-domain identity trust

• Role-Based Access Control (RBAC) - Permission management

• Attribute-Based Access Control (ABAC) - Context-aware authorization

• Privileged Access Management (PAM) - Administrative access controls

🔒 Data Security Patterns

• Encryption at Rest - Data protection in storage

• Encryption in Transit - Secure data transmission

• Key Management Patterns - Secure key storage and rotation

• Data Loss Prevention (DLP) - Sensitive data protection

• Database Security - Securing data stores and access

🌐 Network Security Patterns

• Network Segmentation - Isolating network traffic

• VPC Design Patterns - Secure cloud networking

• Load Balancer Security - Protecting application entry points

• API Security Patterns - Securing REST and GraphQL APIs

• Content Delivery Network (CDN) Security - Edge security implementations

🔍 Monitoring & Compliance Patterns

• Security Information and Event Management (SIEM) - Centralized security monitoring

• Audit Logging Patterns - Compliance and forensics

• Threat Detection - Anomaly detection and response

• Vulnerability Management - Continuous security assessment

• Compliance Frameworks - SOC 2, ISO 27001, GDPR patterns

Key Principles

• Defense in Depth - Multiple layers of security controls

• Principle of Least Privilege - Minimal necessary access

• Fail Secure - Default to secure state on failure

• Security by Design - Built-in security from the start

• Continuous Monitoring - Real-time threat detection

• Incident Response - Rapid security breach response
