CISSP Practice Question: In a multinational financial firm, which is MOST likely to improve user…

Correct Answer: C. Utilizing Single Sign-On (SSO)

Explanation (CISSP Manager Logic):

SSO balances operational efficiency with security by centralizing authentication and reducing the attack surface associated with multiple credential sets. It lowers administrative overhead and improves productivity by streamlining access to diverse multinational resources.

By utilizing SSO, you:

• Reduce help desk costs related to password resets.
• Centralize the enforcement of authentication policies.
• Improve user experience and reduce password fatigue.

While the other options are relevant, they fall short because:

• A: Decentralized systems create management silos, inconsistent security postures, and higher operational costs.
• B: Password policies are a baseline requirement but do not inherently improve access efficiency or simplify the user experience.
• D: Manual reviews are labor-intensive, prone to human error, and do not scale effectively in a multinational environment.

Think like a manager:

Prioritize solutions that provide a "force multiplier" effect—improving security while simultaneously reducing friction for the business and its users.
