100-160 Question 97
Select 3A company is transitioning to remote work and needs to ensure secure access to internal systems for employees working from home. Which of the following technologies should be implemented to provide secure access while protecting sensitive company data?
- A
Virtual Private Network (VPN)
- B
Multi-Factor Authentication (MFA)
- C
Port Mirroring
- D
Role-Based Access Control (RBAC)
- E
Open Wi-Fi Networks for Convenience
Show answer and explanation
Correct answers: A, B, D
Explanation
To implement secure access technologies, a combination of VPN, MFA, and RBAC is essential. VPN ensures encrypted communication, MFA strengthens authentication security, and RBAC enforces the principle of least privilege. These measures collectively protect sensitive company data and provide secure access for remote employees. Port Mirroring and open Wi-Fi networks are either irrelevant or insecure for this purpose.
- A. Correct.
VPNs allow secure encrypted communication between employees and the company’s internal network, preventing unauthorized access and protecting data transmitted over the internet.
- B. Correct.
MFA adds an extra layer of security by requiring users to provide two or more verification factors, reducing the risk of compromised credentials.
- C. Incorrect.
Port Mirroring is used for network monitoring and troubleshooting, not for providing secure access to systems.
- D. Correct.
RBAC ensures that employees only have access to the resources necessary for their job roles, reducing the risk of unauthorized access to sensitive systems.
- E. Incorrect.
Open Wi-Fi networks are inherently insecure and should not be used for accessing sensitive company systems as they are vulnerable to eavesdropping and attacks.
