Secure coding techniques Scenario-Based Questions

1. A developer has implemented a new feature that allows users to upload files. However, there are no restrictions on file types or sizes. How would you handle this situation to ensure secure coding practices are followed?

2. During a code review, you discover that a team member has hardcoded sensitive information such as API keys in the source code. What steps would you take to address this issue?

3. You are tasked with securing an application that processes user inputs from a web form. What strategies would you implement to prevent injection attacks (e.g., SQL injection, XSS)?

4. A client reports that they can access sensitive data in your application without proper authentication. What secure coding practices would you revisit to identify and fix the issue?

5. Your team is adopting a new framework that heavily relies on third-party libraries. What secure coding techniques would you implement to mitigate risks associated with these external dependencies?

6. After conducting a security audit, you notice that your application is susceptible to session fixation attacks. How would you modify the code to prevent this vulnerability?

7. You are responsible for managing access controls in an enterprise application. Describe how you would implement principle of least privilege in the application’s role-based access control.

8. A mobile app developed by your team has been found to expose sensitive user data through insecure data storage mechanisms. What recommendations would you provide to enhance the secure storage of this data?

9. After a major release, users report that they can see each other’s private messages. What debugging and secure coding techniques would you use to identify and rectify this privacy issue?

10. You need to ensure that all communication between your web application and its API is secure. What specific coding practices would you implement to achieve this?
