Authentication & Access Control
Symfony Security component with role-based access control (RBAC). Supports local accounts, LDAP/Active Directory SSO, and configurable password policies with bcrypt/argon2 hashing.
Multi-Tenant Data Isolation
Doctrine ORM tenant-scoped filters automatically isolate data between organizations. Each tenant's data is completely separated at the query level via TenantFilter, preventing cross-tenant data leakage.
Comprehensive Audit Trail
Every entity change, user action, and system event is logged in the AuditLog with timestamp, user, IP address, and before/after values. Full asset custody history tracking for compliance.
Encryption & Data Protection
TLS/SSL encryption for all data in transit. Database credentials secured via environment variables. Sensitive fields (LDAP passwords, API keys) stored encrypted. HTTPS enforced in production.
OWASP Top 10 Protection
Built-in protection against SQL injection (Doctrine ORM parameterized queries), XSS (Twig auto-escaping), CSRF (Symfony form tokens), and clickjacking (X-Frame-Options headers).
API Security
API Platform with token-based authentication for REST endpoints. Rate limiting support, CORS configuration, and input validation on all API resources with Symfony Validator.
File Upload Security
MIME type validation, file size limits, unique filename generation, and storage outside the web root. Upload directory permissions restricted to prevent execution of uploaded files.
LDAP / Active Directory Integration
Native LDAP/AD authentication with group-to-role mapping, automatic user provisioning, directory sync, and support for STARTTLS and LDAPS encryption.
Presentation Layer
Twig templating engine, Bootstrap 5 responsive UI, Progressive Web App (PWA) with service worker for offline mobile support. Real-time dashboards with Chart.js visualization.
Application Layer (Symfony 6.x)
31 controllers handling business logic. Service layer for depreciation calculations, predictive maintenance (health scores, failure predictions), IoT anomaly detection, SLA management, and ERP data transformation.
Security Layer
Symfony Security for authentication/authorization. LDAP provider for AD integration. TenantFilter for data isolation. CSRF protection on all forms. Audit event listeners for change tracking.
Integration Layer
API Platform for REST API. ERP connectors (SAP, Oracle) with bi-directional sync. IoT sensor data collection API. Symfony Messenger for async job processing. Webhook support for external notifications.
Data Layer (Doctrine ORM)
48 entities with MySQL 8.0 backend. Doctrine migrations for schema versioning. Repository pattern for data access. Multi-tenant query filtering. Transaction management and connection pooling.
Infrastructure Layer
Docker-ready deployment. Nginx/Apache web server. PHP-FPM for process management. OPcache for bytecode caching. Symfony Cache for application caching. Log rotation and monitoring.
