CompTIA Security+ (SY0-701) — Question 43

Which of the following would be the best way to handle a critical business application that is running on a legacy server?

Answer options

• A. Segmentation
• B. Isolation
• C. Hardening
• D. Decommissioning

Correct answer: A

Explanation

Segmentation is the best choice because it allows you to separate the legacy application from other parts of the network, reducing the risk of exposure to vulnerabilities. Isolation could limit the application's accessibility, while hardening focuses on improving security without altering the server's setup. Decommissioning would remove the application entirely, which is not a viable option for critical business needs.
