Explain how to secure custom extensions in Magento.

Answer: To secure custom extensions in Magento, follow these best practices:

1. Code Review: Regularly review your code for vulnerabilities, such as SQL injection, XSS, and CSRF.

2. Use Magento APIs: Utilize Magento’s built-in APIs and functionalities to avoid direct database queries and ensure security mechanisms are in place.

3. Input Validation: Validate and sanitize all user inputs to prevent malicious data from being processed.

4. Access Control: Implement proper ACL (Access Control List) restrictions to limit user permissions.

5. Error Handling: Avoid displaying detailed error messages to users. Use logging for debugging instead.

6. Regular Updates: Stay updated with Magento and extension security patches to protect against known vulnerabilities.

7. Security Policies: Implement security policies, such as two-factor authentication and strong password requirements.

8. Secure Configuration: Disable unused features and settings in your extension. Use HTTPS for all transactions.

By following these practices, you can significantly enhance the security of custom extensions in Magento.
