Certified Information Security Manager (CISM) — Question 906

Which of the following BEST reduces the likelihood of leakage of private information via email?

Answer options

• A. User awareness training
• B. Periodic phishing exercises
• C. Email signature verification
• D. Restricted personal use of company email

Correct answer: A

Explanation

User awareness training is crucial as it educates employees about the risks associated with email communications and how to handle sensitive information properly. While periodic phishing exercises and email signature verification enhance security, they do not address the broader issue of employee awareness and behavior. Restricted personal use of company email may help, but it is less effective than comprehensive training in preventing information leaks.
