// THREAT DETECTION AND DATA PRIVACY TERM
Physical Security
Physical security involves measures designed to deny unauthorized access to facilities, equipment, and resources, and to protect personnel and property from damage or harm. It includes things like locks, security guards, fences, and surveillance cameras.
TECHNICAL DEFINITION
Physical security is a foundational component of cybersecurity and defense strategy, encompassing the protection of personnel, hardware, networks, and data from physical actions and events that could cause serious loss or damage. It involves countermeasures like access control systems, surveillance, intrusion detection, and environmental controls to mitigate threats such as theft, vandalism, and unauthorized entry to secure facilities.
BACKGROUND
The Cybersecurity and Infrastructure Security Agency (CISA) is a component of the United States Department of Homeland Security (DHS) responsible for cybersecurity and information technology infrastructure protection. It oversees all levels of the federal government and coordinates with U.S. states to improve cybersecurity against private and nation-state hackers. The CISA is headquartered in Arlington, Virginia.

USAGE NOTE
Physical security is often considered the first layer in a defense-in-depth strategy, as compromising it can bypass even the most robust digital protections.
