Certified Information Systems Auditor (CISA) — Question 362

An organization is planning to implement a work-from-home policy that allows users to work remotely as needed. Which of the following is the BEST solution for ensuring secure remote access to corporate resources?

Answer options

• A. Virtual desktop
• B. Virtual private network (VPN)
• C. Multi-factor authentication
• D. Additional firewall rules

Correct answer: B

Explanation

The best solution for secure remote access is a Virtual private network (VPN) because it encrypts data transmitted over the internet, ensuring confidentiality and security. While a Virtual desktop provides remote access, it may not secure the connection itself. Multi-factor authentication enhances security but does not establish a secure connection, and additional firewall rules are more about controlling access rather than securing remote connections.
