100-160 Question 100
Select 3A company has set up a remote access policy for its employees to securely access internal resources while working remotely. As part of the implementation, you are tasked with ensuring that only authorized users can access the network, and all communication is encrypted. Which of the following technologies should you implement to achieve this?
- A
Virtual Private Network (VPN)
- B
Multi-Factor Authentication (MFA)
- C
Password-based access without additional layers of security
- D
Firewalls configured to block unauthorized IP addresses
- E
Biometric authentication systems
Show answer and explanation
Correct answers: A, B, E
Explanation
To implement secure access technologies, a combination of VPN for encrypted communication, MFA for robust user authentication, and advanced authentication methods like biometrics ensures both secure and user-verified access to resources. Password-only access and firewalls alone are insufficient to meet the requirements of a secure remote access policy.
- A. Correct.
VPNs provide a secure tunnel for encrypted communication, ensuring that remote access to the network is protected from interception.
- B. Correct.
MFA adds an additional layer of security by requiring users to verify their identity through multiple factors, such as a password and a mobile authentication app.
- C. Incorrect.
Relying solely on password-based access is insecure and does not meet the requirements for secure access technologies, as it is vulnerable to password theft or guessing.
- D. Incorrect.
While firewalls are important for network security, they alone cannot ensure secure remote access or user authentication.
- E. Correct.
Biometric authentication systems provide a secure and user-friendly method for verifying user identity, ensuring only authorized personnel gain access.
