CompTIA CASP+ Practice Test

What control measure would assist in protecting against unauthorized access during remote operations?

1. Implementing strong password policies.

2. Regular security audits.

3. User access restrictions based on roles.

4. Multi-factor authentication for all systems.

The correct answer is: Multi-factor authentication for all systems.

Choosing multi-factor authentication for all systems is an effective control measure to protect against unauthorized access during remote operations. This approach requires users to provide multiple forms of verification before gaining access to a system, significantly enhancing security. During remote work, the risk of unauthorized access increases due to potentially insecure networks and the use of personal devices. By implementing multi-factor authentication, even if an attacker obtains a user's password, they would still need another form of identification, such as a one-time code sent to a mobile device or a biometric factor. This layered approach creates a barrier that makes it much harder for unauthorized individuals to access sensitive systems or data. While other options such as strong password policies, regular security audits, and user access restrictions based on roles contribute to an overall security strategy, they do not provide the same level of layered security that multi-factor authentication does. Password policies can be circumvented if passwords are stolen, audits may identify vulnerabilities after they occur, and role-based access helps control permissions but does not prevent login attempts without proper verification. Multi-factor authentication, therefore, is a critical component in maintaining security during remote operations.
