Production Security Checklist for Laravel Applications

A secure Laravel application is not only about code. It is also about configuration, secrets, and safe operational defaults.

    ## Core checklist
    - APP_DEBUG=false in production
    - strong passwords and hashing
    - CSRF protection for forms
    - strict validation for all input
    - rate limit login endpoints
    - least privilege DB user
    - secure file uploads (type + size)
    - avoid exposing stack traces
    
    ## Security flow (high-level)

      A[User Input] --> B[Validation]
      B --> C[Authorization]
      C --> D[Business Logic]
      D --> E[(Database)]
    ```
    
    In the next tutorial, we will complete a real advanced project using these practices.
