Objectives
• Explain physical security strategies
•Describe physical security controls
•Understand the role of physical security
3
4 Key Strategies
1. Territoriality
2. Natural Surveillance
3. Activity Support
4. Access Control
4
Territoriality
Most people tend to protect area that they feel is their own, and have a certain amount of respect for other’s. Fences, pavement treatments, signs and landscaping all help to express ownership.
5
Natural Surveillance
• This is almost entirely based off of the fact that criminals do not want to be seen.
• Place physical activities, features and people in a way that they can be observed
• Remove trees, sheds, bushes and other sight obstructions
6
Access Control
• Properly located entrances/exits
• Fencing
• Lighting
• Receptionist at a front desk
• A neighbor sitting on their front porch
7
An Overview of Physical Controls
Concentric Zone Theory – based on the premise that the more valuable an asset is, the more protection it needs
3 Basic Lines of Physical Defense:
1. The perimeter of the facility
2. The building exterior
3. The interior
8
Locks
• Key, key card or smart card operated
• Remains one of the oldest, most commonly used methods of access control
9
Biometrics
The science of using individual physiological features or behavioral characteristics to positively identify a person
Examples: fingerprint, iris/retinal scans, hand geometry, voice, et al.
10
Lighting
• Intruders want darkness to cover their actions
• 3 out of 4 commercial burglaries are committed within buildings with little or no light
• Types:
1. Continuous
2. Standby
3. Moveable
4. Emergency
11
Lighting
•Perimeter Lighting• Floodlights•Street lights• Fresnal units•Searchlights
12
Alarm uses
• Burglar• Fire• Temperature•Humidity•Water flow• Electrical power
13
Alarm system types
Local – sound on the premises only• Proprietary – a constantly-manned alarm panel operated by the owner• Central Station – similar to proprietary, except usually operated off premises by an alarm company• Police Connected – the alarm is directed via phone lines to the nearest police dept.
14
Alarms – False Alarms
•More than 90% of all intrusion alarms are false alarms, resulting in needless expense and risks on the part of responders.
• Because of the high number of false alarms, many cities prohibit alarms connected directly to the police department.
15
Closed Circuit Television (CCTV)
• A generic term, generally meaning a system in which a number of video cameras are connected in a closed circuit or loop, where the images are sent to a central television monitor or recorded.
• CCTV systems range from basic system to very complicated networks.
16
Closed Circuit Television (CCTV)
Cameras may be overt or covert, or semi-covert.•Overt – out in the open• Covert – hidden• Semi- Covert – cameras are in public view but behind a one-way transparent covering.
17
CCTV other technology
• Internet Protocol Video (IP)• Video can be sent across a company’s data network
so that it can be viewed wherever the company chooses.• These can cause bandwidth and digital storage
issues for a company’s network.
• Thermal Imaging – operates on the principle that all objects emit infrared energy that can be seen using a thermal imager
• Night Cameras – most popular kind use image intensification that amplifies available visible and near-infrared light to achieve better vision
18
Privacy concerns…
• There is concern over the amount of, or rather lack of, privacy by private, non-criminal citizens through the extensive use of surveillance methods.
• Some cities are passing legislation to govern these types of devices and their use.
19
The Perimeter
• Fences – 2 basic types•Ornamental•Chain Link – effectiveness can be increased by adding razor wire, barbed wire, etc.
20
The Perimeter
• Surveillance Cameras
•Vehicle Barriers•Active – require some action by a person or equipment to be raised into place•Passive – a fixed device with no moving parts, such as guard rails, concrete poles, etc.
21
The Perimeter
•Patrols•Security Officers•Patrol or Guard Dog units – roam alone inside a perimeter or building to deter intruders
22
The Perimeter
• Signs
•Physical Layout When possible, we should always try to maintain a clear zone of 20 feet on either side of the perimeter
23
Building Exterior controls
• For some facilities, the exterior is the first line of defense.
• Panic or Crash BarsA device located on the inside of a door only. It allows the door to opened in case of a fire, but has no hardware on the outside that can be used to open the door.
24
The Building Exterior
• Keys for effective security:• Strong, locked doors• Limited number of entrances• Secured openings (>96 sq. inches)• Alarms• Surveillance• Lighting
25
The Building Interior
• Internal physical controls are usually required along with external controls.
• Secure areas should be separated from non-secure areas if possible.
26
The Building Interior - Safeguards:
• Locks• Alarms•Mirrors•Document shredders• Vaults/ safes
• Bolt down large, moveable equipment• Lock down devices on office equipment• Surveillance systems
27
The Command Center
•Should be linked to the security control center
•Should be in a tightly controlled area
•Can also monitor access
• Increasingly, staff members of the command center can also handle computer network issues if need be.
28
The Physical Security System
• The goal is to provide the amount of security needed - neither too much nor too little.
• This is a balancing act between aesthetic, operational, safety and security needs.
29
The Physical Security System
• Physical Security Users: a group comprised of the people who own the property being protected, the people who work at or visit the facility, and the security forces themselves.
• Physical security footprint – the mark left during or after a security action that the public sees and lets them know security is present.
