physical security
Guards and locks
Physical security refers to measures that protect people, property, and assets from physical threats—theft, vandalism, natural disasters, unauthorized access.
It encompasses locks, fences, guards, surveillance cameras, access control systems, and building design.
The term distinguishes tangible protection from cybersecurity or digital safeguards: The company invested heavily in physical security after the break-in.
In corporate and government contexts, physical security often works alongside information security as complementary disciplines.
