 Our rules cover essential security domains:
 
-- **🔐 Cryptography**: Safe algorithms (including post-quantum cryptography), secure key management, certificate validation
-- **🛡️ Input Validation**: SQL injection prevention, XSS protection, command injection defense
-- **🔑 Authentication**: MFA best practices, OAuth/OIDC, secure session management
-- **⚡ Authorization**: RBAC/ABAC, access control, IDOR prevention
-- **📦 Supply Chain**: Dependency security, SBOM generation, vulnerability management
-- **☁️ Cloud Security**: IaC hardening, container security, Kubernetes best practices
-- **📱 Platform Security**: Mobile apps, web services, API security
-- **🔍 Data Protection**: Privacy, encryption at rest/transit, secure storage
