With a 10,000+ year history and many tens of thousands of practitioners, it may seem odd to maintain – in a periodical devoted to security no less! – that physical security isn’t a real field. But in many ways, it’s not.
We define physical security as measures taken to protect tangible physical assets (people, buildings, money, drugs, museum artifacts, etc.) from harm. But enterprise physical security also involves deploying corporeal means (access control devices, guards, fences, etc.) to protect intangible assets (intellectual property, PII, sensitive information, digital data, etc.).
