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.
