Network Defense Essentials (NDE) Practice Exam

What practice can help protect mobile applications against cyberattacks?

1. Regularly updating apps

2. Avoid using query string while handling sensitive data

3. Using public Wi-Fi

4. Sharing passwords

The correct answer is: Avoid using query string while handling sensitive data

While the option concerning avoiding the use of query strings for handling sensitive data is essential for safeguarding mobile applications against cyberattacks, the practice of regularly updating apps should not be overlooked. Regular updates often include patches for known vulnerabilities, making them critical in enhancing the security of applications. In the context of cyber threats, mobile applications are particularly vulnerable to attacks, and mismanagement of sensitive data can lead to significant breaches of security. Query strings are often easily manipulated by attackers and can expose sensitive information if not handled securely. Implementing secure coding practices, including avoiding the use of query strings for sensitive data, is crucial in preventing unauthorized access and ensuring user data protection. The other options either compromise security or do not directly contribute to safeguarding applications. Public Wi-Fi, for instance, is typically insecure and can lead to data interception, while sharing passwords poses a direct risk to account security. Hence, adhering to secure practices such as avoiding insecure methods for data handling is pivotal in defending mobile applications against potential cyber threats.
