Exam SSCP topic 2 question 159 discussion

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.
