To prevent XSS and enforce web security, you must validate and sanitize all user input at boundaries and apply browser security measures like Content Security Policy (CSP) and secure cookies to mitigate common vulnerabilities.

The best way to audit a new web project for secure defaults is to perform a comprehensive code review across frontend and backend layers, ensuring input validation, authorization, and safe data handling controls are enforced.

Yes, you need to validate input on both frontend and backend layers because web security assumes hostile input and untrusted environments by default, requiring boundary validation to protect the application effectively.

Content Security Policy (CSP) works with secure cookies by enforcing browser security measures that restrict resource loading and protect data in transit, preventing common vulnerabilities like cross-site scripting and session hijacking.

You need to enforce authorization and safe data handling in deployment workflows whenever designing or auditing web applications, ensuring security best practices are applied across the entire lifecycle from code review to deployment.

Yes, you can use this approach to secure authentication flows because the web security scope explicitly enforces security best practices across authentication, authorization, and data handling boundaries.
