Certified Information Systems Auditor (CISA) — Question 817

An organization has recently become aware of a pervasive chip-level security vulnerability that affects all of its processors. Which of the following is the BEST way to prevent this vulnerability from being exploited?

Answer options

• A. Install vendor patches.
• B. Review security log incidents.
• C. Implement security awareness training.
• D. Review hardware vendor contracts.

Correct answer: A

Explanation

Installing vendor patches is the most effective way to address a chip-level security vulnerability, as it directly targets the flaw with official fixes provided by the manufacturer. The other options, while useful for overall security, do not directly mitigate the specific vulnerability in the processors.
