Which one of the following is part of the security metric to consider in selecting the appropriate labels for an administrative system?

Tamper resistance is a security metric because it ensures labels on administrative systems cannot be covertly removed, replaced, or altered - which could otherwise facilitate unauthorized access or obscure accountability. This property directly addresses the integrity of the labeling system from a security standpoint, distinguishing it from purely physical or environmental durability characteristics.

Smudge resistance is a legibility and durability metric that addresses how well a label maintains readability, not whether it has been tampered with.

Temperature rating is an environmental performance specification that defines operating limits, not a security consideration.

Adhesive type relates to how well a label bonds to a surface and is an installation or durability metric, not a security metric.

Moisture content is a material or environmental characteristic related to label degradation, not a security metric relevant to label selection.
