Introduction to Physical Security

Study Notes

Defining Physical Security

Physical security protects people, assets, and information from unauthorized actions like access, use, disclosure, disruption, modification, or destruction.
It safeguards physical premises, systems, assets, and personnel through various measures and controls.
Its goal is to deter and prevent malicious acts and accidental incidents.

Key Aspects of Physical Security

Access Control: Regulates movement of individuals and materials. Includes entry points, perimeter fences, surveillance, and security personnel. Strong access control uses identification and authorization methods (badges, biometric scans, checkpoints).
Perimeter Security: Protects the facility boundary, preventing unauthorized entry/exit. Involves physical barriers, surveillance technology, patrols, and alarm systems. Essential for preventing theft, vandalism, and intrusion.
Personnel Security: Protects employees and visitors, ensuring personnel security. Emphasizes security training programs and background checks. Includes procedures for handling emergencies and responding to threats.
Environmental Security: Maintains a secure environment by controlling factors like lighting, temperature, and other conditions, deterring or revealing threats. Considers vulnerability to natural disasters and weather events.
Asset Protection: Safeguards valuable assets and resources through measures like locking, surveillance, and protection of sensitive data.
Surveillance and Detection: Monitors activities to detect unauthorized actions. Uses security cameras, sensor systems, and alarms for early detection of intrusions. Includes monitoring electronic and data systems.

Physical Security Measures

Barriers: Walls, fences, gates, and bollards limit access and create obstructions.
Surveillance Systems: Video cameras, motion detectors, and intrusion alarms identify, monitor, and deter threats.
Security Personnel: Guards, patrols, and officers monitor areas, respond to threats, and enforce security policies.
Access Control Systems: Keycard readers, biometric scanners, and security checkpoints restrict access to authorized personnel.
Alarm Systems: Alert security personnel to security breaches or emergencies.
Environmental Controls: Manage factors like lighting, temperature, humidity to enhance security.

Importance of Physical Security

Protecting lives and property: Prevents loss/damage, ensuring people's safety.
Preventing theft and vandalism: Deters criminal activities, reducing losses.
Maintaining business operations: Protects facility operations and data from disruption.
Ensuring regulatory compliance: Follows industry and government safety, security, and data protection regulations.
Protecting sensitive or confidential information: Prevents unauthorized access or disclosure.

Considerations for Physical Security Design

Risk Assessment: Identifies potential threats and vulnerabilities to customize security measures.
Site Analysis: Examines the facility's layout and characteristics, ensuring threats are mitigated.
Cost-Benefit Analysis: Evaluates security measure costs against potential benefits.
Integration with other security systems: Ensures interoperability and benefits across different security systems.
Continuous Improvement: Regularly reviews and adjusts security measures based on evolving threats and vulnerabilities.
