Exam SSCP topic 2 question 159 discussion

Add-on security refers to security controls or mechanisms that are added to a system after it has already been developed or deployed. These are not part of the original design and are typically implemented to address new threats, vulnerabilities, or compliance requirements that were not considered initially.

D, This is not in reference to physical security.

A. Physical security complementing logical security measures. Add-on security typically refers to physical security measures that complement or supplement logical security measures in an information system. While both physical and logical security are essential for overall security, add-on security specifically focuses on additional physical safeguards, such as biometric access controls, surveillance cameras, locked server rooms, and secure hardware tokens, to enhance the security of an information system. These physical measures are added to strengthen the overall security posture of the system beyond the purely logical or software-based security measures.
