Correct Answer is D

Explanation

A. Leilani should have opened her emails in a more private location only she can access. – This action may protect sensitive information from physical observation but does not prevent malware.

B. Leilani should have used a more complex login when accessing her emails. – A stronger password enhances security but does not address the risk of opening suspicious attachments.

C. Leilani should have changed her email password more frequently. – While regular password updates can help with unauthorized access, they do not protect against malware in suspicious attachments.

D. Leilani should run a virus check on the email with the file attachment from the unfamiliar source. – Running a virus scan on suspicious attachments is the best preventive action, helping to detect and mitigate threats before opening potentially harmful files.

Correct Answer is D

Explanation

A. Usability testing – Usability testing evaluates user-friendliness and ease of use but does not assess security elements like password challenges and data confidentiality.

B. Load testing – Load testing evaluates system performance under various levels of usage to ensure it can handle high traffic, but it does not focus on security aspects.

C. System testing – System testing assesses the overall functionality of the system but doesn’t specifically address security features like password management and data confidentiality.

D. Security testing – Security testing is the best choice here as it assesses the protection mechanisms of the system, including password security, data confidentiality, and breach response plans.
