What does 'environmental design' refer to in the context of physical security?

'Environmental design' in the context of physical security refers to the practice of modifying the built environment to create safer spaces and reduce opportunities for crime. This concept is rooted in theories such as Crime Prevention Through Environmental Design (CPTED), which suggest that effective design can discourage criminal behavior.

By altering the physical environment—such as improving lighting in public areas, maintaining clear sightlines, creating natural surveillance opportunities, and ensuring that spaces are used effectively—security professionals can significantly impact the likelihood of criminal activities.

Options that focus on colors for vehicles, ergonomic designs, or digital security protocols do not align with the concept of environmental design as they pertain to specific aspects of security equipment or processes rather than the broader physical environment and its influence on crime prevention.
