Dive deep into secure direct object reference handling techniques for TypeScript applications through our hands-on labs. Learn to prevent unauthorized post access, cross-user data manipulation, role privilege escalation, and resource ownership bypass that compromise application security. Explore validation strategies such as session-based authentication, resource ownership validation, middleware-based security checks, and role-based authorization patterns. Create resilient web applications that properly authenticate, authorize, and control access to user resources across your TypeScript web applications.
