Effective CISSP Questions

Your company decides to sell toys online and ships globally. The target customers are house-hold consumers. An in-house team is responsible for developing the online shopping website. To maximize security assurance and market share, which of the following is the best authentication solution?
A. Iris
B. Fingerprint
C. Password
D. Retina

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is C. Password.

All the four choices of the question are technically feasible, but password authentication is the best answer. Security is not only a technical issue but a business concern. Security solutions must be cost-effective (economy of mechanism) and psychologically acceptable.

Biometric-based authentication solutions are trustworthy, but they require scanning or reader devices. Fingerprint, iris, retina are biometric mechanisms that are commonly implemented as the second factor of authentication. They are complicated, costly, and inconvenient to house-hold consumers. It may hurt the penetration of market share.
