Explanation

The foundational principle in physical security is proportionality: the cost and effort of implementing controls must be justified by the value of what is being protected (a cost-benefit or risk-based analysis). Spending $1 million to protect a $10,000 asset is not rational, while under-protecting a critical asset is negligent. Technology (C), number of entry points (D), and enforcement time (B) are all secondary considerations that feed into this cost-versus-value calculation.
