What term describes activities performed by a security officer for compensation?

The term "Security Services" accurately captures the activities performed by a security officer for compensation. This term encompasses a wide array of functions that security personnel undertake as part of their professional responsibilities, which may include event security, access control, surveillance, and emergency response, among others.

When referring to 'security services,' it emphasizes the professional and service-oriented nature of the work conducted by security officers. This designation reflects the contractual relationship and the expectation of compensation for the services rendered, underscoring their role in protecting people, property, and information.

In contrast, while 'security operations,' 'security duties,' and 'security functions' may describe various aspects of a security officer's role, they do not specifically highlight the aspect of being compensated for the activities as distinctly as 'security services' does. Thus, 'security services' is the most precise term in this context.
