CompTIA Security+ (SY0-701) — Question 577

Which of the following is the first step to secure a newly deployed server?

Answer options

• A. Close unnecessary service ports.
• B. Update the current version of the software.
• C. Add the device to the ACL.
• D. Upgrade the OS version.

Correct answer: B

Explanation

The correct answer is B because updating the software ensures that any known vulnerabilities are patched, providing a secure baseline. While closing unnecessary service ports (A) and adding the device to the ACL (C) are important security measures, they should be done after ensuring the software is up to date. Upgrading the OS version (D) may not be necessary if the current version is already secure and up to date.
