Network Defense Essentials (NDE) Practice Exam

Which measure helps protect mobile data from unauthorized access?

1. Storing sensitive data on cloud

2. Maintaining access control for devices and data

3. Using simple passwords

4. Logging out after use

The correct answer is: Maintaining access control for devices and data

Maintaining access control for devices and data is critical in protecting mobile data from unauthorized access. Access control mechanisms ensure that only authorized users have the ability to view or manipulate sensitive information. This involves implementing strong authentication methods, such as biometric scans, complex passwords, or multifactor authentication, to verify identity before granting access. By managing who can access devices and data, organizations can mitigate risks associated with unauthorized access, thereby safeguarding sensitive information. This approach not only applies to user credentials but also extends to permissions related to applications and services that users interact with. Strong access control policies can prevent data breaches caused by unauthorized individuals who may exploit security vulnerabilities. In addition, maintaining an inventory of devices and regularly reviewing user access levels can further bolster defenses against unauthorized access. In contrast, while storing sensitive data on the cloud and logging out after use are practices that may enhance security, they do not specifically address the fundamental need for controlled access to that sensitive data and the devices it's stored on. Using simple passwords can undermine security as they are often easy to guess or brute-force. Thus, maintaining robust access control is the most effective measure for protecting mobile data from unauthorized access.
