Certified Information Systems Auditor (CISA) — Question 933

Which of the following is the GREATEST security concern specific to virtualized environments?

Answer options

• A. A management console grants administrative access.
• B. Unmanaged memory may leak data between guests.
• C. Performance issues of the host can affect security capabilities.
• D. Vulnerabilities can result in exposure of sensitive data.

Correct answer: B

Explanation

The correct answer is B because unmanaged memory can allow data to be shared unintentionally between different virtual machines, posing a serious security threat. While A, C, and D are valid concerns, they do not specifically pertain to the unique challenges faced in virtualized environments as directly as unmanaged memory issues do.
