Access control in Drupal is enforced by applying route permissions and access checks to prevent unauthorized access. This involves auditing route definitions and controller handlers to verify that proper permission requirements are configured across custom modules.

Preventing SQL injection and XSS in Drupal requires using parameterized queries for database access and proper output escaping for rendering. Applying these controls ensures user input is securely handled across forms, controllers, and AJAX endpoints to block common web vulnerabilities.

CSRF protection for Drupal form submissions and AJAX endpoints is implemented by securing user input handling and validating tokens. This prevents cross-site request forgery attacks by ensuring that state-changing actions are explicitly authorized by the current user session.

Yes, Drupal file upload validation can enforce extension, MIME-type, and size checks. This secure validation process prevents malicious file uploads by verifying that uploaded files match expected types and conform to defined security constraints.

Auditing Drupal routing and controllers is needed whenever adding new routes, custom forms, or AJAX endpoints to a module. This process verifies that access checks, CSRF tokens, and input validation are properly applied to prevent unauthorized access and injection vulnerabilities.
