Introduction

Web applications are complex systems that require thorough testing to ensure they function as expected and are secure from threats. This checklist is designed to cover a wide range of potential issues, from security vulnerabilities to usability problems, helping you to deliver a robust and secure web application.

Checklist Categories

Authentication and Authorization

• Login and Logout:

  • Ensure protection against brute force attacks.
  • Test for SQL injection vulnerabilities in login forms.
  • Verify proper session invalidation after logout.

• Password Policies:

  • Enforce strong password policies.
  • Ensure secure storage of passwords (e.g., hashed and salted).

• Authorization:

  • Prevent unauthorized access to resources.
  • Test for horizontal and vertical privilege escalation.

Session Management

• Session ID Security:

  • Ensure session IDs are complex, unique, and securely generated.
  • Regenerate session IDs upon login.

• Session Expiry:

  • Implement session expiration after inactivity.

• Secure Cookies:

  • Mark session cookies as HttpOnly and Secure.

Input Validation

• Cross-Site Scripting (XSS):

  • Test for reflected, stored, and DOM-based XSS vulnerabilities.

• SQL Injection:

  • Ensure input fields are protected against SQL injection.

• Cross-Site Request Forgery (CSRF):

  • Verify CSRF tokens are used for state-changing requests.

• File Uploads:

  • Validate and sanitize file uploads.
  • Store uploaded files securely, ensuring they are non-executable.

Data Handling

• Sensitive Data Exposure:

  • Encrypt sensitive data both at rest and in transit.

• Data Integrity:

  • Validate and sanitize data before processing.

• Error Handling:

  • Prevent error messages from exposing sensitive information.

Business Logic

• Workflow Bypasses:

  • Test for ways to bypass critical steps in business processes.

• Race Conditions:

  • Check for issues when multiple users interact with the same object or process simultaneously.

• Rate Limiting:

  • Ensure rate limiting is implemented to prevent abuse.

User Interface and User Experience (UI/UX)

• Responsiveness:

  • Ensure the application is responsive across different devices and screen sizes.

• Accessibility:

  • Verify that the application meets accessibility standards (e.g., WCAG).

• Error Messages:

  • Provide clear and user-friendly error messages.

• Navigation:

  • Ensure that navigation is intuitive and consistent across the application.

Performance and Scalability

• Load Testing:

  • Conduct load testing to identify performance bottlenecks.

• Caching:

  • Implement appropriate caching strategies to improve performance.

• Database Optimization:

  • Optimize database queries and indexing for efficiency.

Compliance and Legal

• Data Privacy:

  • Ensure compliance with data privacy laws (e.g., GDPR, CCPA).

• Terms of Service and Privacy Policy:

  • Provide clear and accessible terms of service and privacy policy documents.

• Cookie Consent:

  • Implement cookie consent mechanisms as required by law.
