Architectural lighting is lighting planned as part of a building or interior design, rather than added later as decoration. It is integrated with the space to shape visibility, mood, and movement, using careful placement, fixture choice, and beam direction. In practice, it can highlight entrances, corridors, stairwells, and work areas while minimizing glare and dark corners.
In cyber security, architectural lighting matters because physical and digital security often overlap. Well-designed lighting improves camera coverage, supports access control, and reduces opportunities for trespass, tailgating, or covert device placement near doors, racks, and network rooms. Poor lighting can make surveillance less effective and can help attackers hide actions during physical intrusion or sabotage. Defenders use architectural lighting as part of layered security: to make spaces observable, to support incident review, and to create environments where unusual behavior is easier to detect.
