The term that describes the outermost protective layer of a security zone is the "Assessment Zone." This zone serves as the initial area where potential threats are identified and evaluated before they can progress towards more secure areas. Its primary function is to provide the first line of observation and monitoring, allowing personnel to gather intelligence on any possible threats and assess their intentions without exposing resources or individuals to potential harm.

In contrast, the other terms refer to different aspects of security zones. The threat zone typically indicates an area where a credible threat exists or is perceived. The reaction zone is usually a layer where immediate responses can be enacted against threats that have breached initial defenses. The intercept zone typically pertains to an area where actions are taken to intercept or neutralize a threat before it can reach its target. Understanding the function of the Assessment Zone is crucial, as it plays a fundamental role in the layered defense strategy of security operations.
