What type of control is additional exterior lighting considered in terms of security upgrades?

Additional exterior lighting is classified as a deterrent control in terms of security upgrades because it serves to deter potential intruders or criminals from attempting to breach a property. The presence of light increases visibility, which can discourage illicit activities since would-be offenders prefer to operate in darkness to avoid being seen.

When a space is well-lit, it not only enhances safety for individuals using the area but also makes it more difficult for unauthorized activities to go unnoticed. This proactive measure creates an environment where criminal behavior is less likely to occur, making it an effective strategy to deter threats before they can manifest.

Deterrent controls often aim to prevent incidents by making the effort to commit a crime appear more difficult or risky, which is precisely what additional lighting achieves by minimizing concealment opportunities for potential malefactors.
