You have been asked to spec the physical security requirements related to the protection of assets for a new data center. The most common potential for damage categories you have considered include…

Aircraft flight paths are a site selection and structural risk consideration but are not one of the five standard physical damage categories in this classification taxonomy.

Proximity to high-speed rail links is a vibration and site planning concern but is not included in the five standard physical damage categories.

Liquids are a primary physical threat category because water intrusion from flooding, plumbing failures, leaking cooling systems, or fire suppression discharge can cause catastrophic damage to electronic equipment. The standard physical threat taxonomy used in data center security planning formally includes liquids alongside temperature, gases, organisms, and projectiles as the five core categories of environmental and physical damage risk.

Parking lot exits are a perimeter access control concern, not one of the five established physical damage categories for asset protection.

Extreme winds are a structural and site selection factor but do not fall within the five standard physical damage categories in this framework.
