How do security systems protect tangible property such as cash and equipment?

Security and protection systems safeguard tangible property—such as cash, equipment, and finished products—by employing passive and preventive measures that integrate physical infrastructure, specialized technology, and personnel management.12

Physical Security Measures

Physical protection relies on architectural design and specialized equipment to control access and deter theft.2
* Architecture: Buildings are designed to limit entry points and manage traffic patterns, while perimeter barriers like walls and fences prevent unauthorized access.2
* Storage and Access: Valuables like cash are secured in reinforced containers such as safes, vaults, or lockboxes. Access is often controlled through locks, badges, or automated systems requiring unique codes or biometric verification.23
* Surveillance and Detection: Organizations utilize cameras, closed-circuit television, and intrusion-detection devices (e.g., photoelectric cells) to monitor premises. Lighting systems are also used to deter illegal entry and assist in surveillance.2

Personnel and Procedural Controls

Because internal threats like embezzlement or pilferage are significant risks, security programs emphasize personnel integrity.12
* Screening: Background investigations and vetting help ensure only trustworthy individuals are hired.2
* Management Controls: Procedures such as dual responsibility—where tasks are subdivided so employees check one another's work—and periodic audits against physical inventories help maintain security.2
* Monitoring: Vulnerability tests, such as planting deliberate errors to see if they are reported, and the use of undercover investigators help monitor the effectiveness of these systems.2
