Physical Security Measures

Physical security measures are the tangible, non-digital protections implemented to safeguard people, assets, and infrastructure from unauthorized access, damage, or theft. This includes controls like locks, surveillance cameras, access control systems, and environmental safeguards. It is a foundational aspect of overall security strategy, complementing cybersecurity to create a holistic defense.

Also known as: Physical Security, Physical Security Controls, Hardware Security, Facility Security, Physical Protection

Why learn Physical Security Measures?

Developers should understand physical security measures when designing or deploying systems in sensitive environments, such as data centers, government facilities, or IoT devices in public spaces. This knowledge helps ensure compliance with regulations (e.g., GDPR, HIPAA), prevent physical tampering with hardware, and integrate security into the full lifecycle of a product, from development to deployment.
