The Integration of People, procedures, and equipment deployed to safeguard people, property, and information and to prevent unauthorized access to assets
Physical Security
What are the four D’s of Physical Security?
Deter
Detect
Delay
Deny
Of the 4 D’s which is always the first objective?
Deter
What must be included in the Detect portion of the 4 D’s?
Assessment
What must happen for an event to be considered detected?
You must be able to determine what caused the event.
What consists of placing multiple layers of concentric security features that provide 360-degree protection without gaps or weaknesses?
Defense-in-Depth
In Defense-in-Depth what is consider the simple approach?
To use three main layers, the outer layer, the middle layer, and the inner layer
IN regard to Defense-in Depth what does the outer layer typically consist of?
barriers, protective lighting, signage, and intrusion detection.
What is the purpose of control measures at the perimeter in regard to Defense-in-Depth?
They typically define the property boundary and channel both people and vehicles to the designated access points.
Defense-in-Depth. What does the middle layer typically comprise?
The exterior of the building on the site and may include doors, windows, building facade, walls, and other opening such as ventilation intakes and skylights.
Defense-in Depth. What does the Inner layer typically consist of?
Window and door protection devices, barriers, and reinforced walls/doors, access control devices, intrusion detection systems, video surveillance, protective lighting, and signage.
Regarding Defense-in-Depth where are the highest valued assets located?
The inner layer
What must you know in order to calculate the effectiveness of the physical security feature also known as the Design Basis Threat (DBT)?
- Identify the assets to be protected
- The adversary’s skills including tools and tactics
- The pathway the adversary might use.
What is the critical detection point (CDP)?
The point where the delay time exceeds the response force time
What should the concept of design follow, as a minimum?
- Facility Layout and Utilization
- Protection Strategy
- Structural and Electronic Security Systems
- Security Officer operations and other human support
- Physical Security Program Management
What is point security?
When the outer perimeter is loosely controlled and the primary focus is on individual buildings within the perimeter or spaced within the buildings, such as restricted areas.
What is Area Security?
A site where the perimeter and entry portals have a higher level of control and security features.
What are the key considerations planners should consider when designing a site of facility?
- Placement of hazardous materials
- air intake and exhaust design
- utilities including water, electric, natural gas, communications, sewer, drainage culverts, etc.
- neighboring facilities and operations
- Contingency Planning
What are three main contemporary challenges with security professionals?
- Standards and Guidelines
- Emerging Technology
- Security Education
What does Defense-in- Depth consist of?
Multiple security measures around an assett
What does balanced protection mean?
all protective measures are evenly deployed around an asset.
What is Design Basis Threat?
The basis of PPS design used to protect an asset by analyzing adversary skills, tools, tactics, and the pathway an adversary might use to compromise the asset.
What is PPS?
The Physical Protection System
What needs to happen to make the PPS effective?
It should be balanced between the various forms of security measures (structural, electronic, and procedural)
