Systems Security Certified Practitioner (SSCP) — Question 137

Which of the following best defines add-on security?

Answer options

• A. Physical security complementing logical security measures.
• B. Protection mechanisms implemented as an integral part of an information system.
• C. Layer security.
• D. Protection mechanisms implemented after an information system has become operational.

Correct answer: D

Explanation

The correct answer, D, refers to security measures that are added after the initial deployment of a system, which aligns with the concept of add-on security. Options A and B describe forms of security that are integrated or physical, rather than added post-deployment, while option C is too vague and does not specifically define add-on security.
