Which of the following practices can make iOS devices vulnerable to mobile-based security incidents?

Disabling the Do Not Track feature can indeed make iOS devices more vulnerable to mobile-based security incidents. When this feature is turned off, it allows websites and applications to track user behavior and collect data without restrictions. This increased tracking can lead to privacy invasions and exposes users to targeted attacks, such as phishing or social engineering, as attackers may use the collected data to create more convincing scams.

In contrast, enabling the Do Not Track feature helps enhance privacy by minimizing the amount of data that websites and applications can collect about the user, thus reducing the overall risk of targeted attacks based on user behavior and preferences. Regularly updating apps and using trusted networks are essential practices for maintaining security, as they help protect against vulnerabilities and unauthorized access.
