Concepts of Security Anything made by man can be defeated by man. Low level: home or small business. Highlevel High level: nuclear power plant, military installations and some prisons. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
7
Concepts of Security continued psychological The concept of security is as much psychological as it is physical. Example is there any physical obstacle presented by security lighting or is it a psychological deterrence? ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
9
Concepts of Security continued Cost - effectiveness is one of the most difficult concepts of security. cost value Does the cost of protecting it outweigh its value? ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
10
CONCEPTS of SECURITY (Continued) Put yourself mentally in the role of the actor (Thief - Perpetrator)! accessibilityvulnerability Test accessibility and vulnerability Draw on your experience and knowledge of local conditions and MO’s Consider the total environment. Pay attention to detail. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
12
QUESTION? WHY IS IT IMPORTANT FOR YOU TO PUT YOURSELF IN THE MIND OF A CROOK? ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
13
CONCEPTS of SECURITY (Continued) SECURITY BARRIERS: Defined as: Anything that restrains or obstructs passage. Restrain: to hold back from action Obstruct: to make difficult or oppose passage. Security measures are taken to reduce losses to criminal acts.
14
Three Lines of Defense devices Dozens of security devices and procedures may be placed to reduce losses caused by crime. measures To discuss these measures systematically we present them within the context of the three lines of defense. They are: ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
15
CONCEPTS of SECURITY THREE LINES OF DEFENSE: P PP Perimeter B BB Building Exterior B BB Building Interior Perimeter barriers will not provide complete protection for a building.
16
Concepts of Security Perimeter Barriers physical Perimeter barriers define the outside perimeter of a site and are designed for physical and psychological deterrence. Perimeter barriers will not provide complete protection a for a building. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
17
Concepts of Security Perimeter Barriers Barrier considerations: 1.Maintenance is important to any barrier. 2.Channel personnel and vehicles. 3.Must not obstruct visibility. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
18
Concepts of Security Perimeter Barriers - Fences chain link fence Many people think of the traditional chain link fence with barbed wire strands at the top when they think physical perimeter barrier. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
19
Concepts of Security Perimeter Barriers - Fences psychological A definite psychological barrier as well as physical; consequently a person may react emotionally when discussing need for physical barrier to be improved or upgraded. appearance Options as far as general nature and appearance of fencing. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
21
Concepts of Security Perimeter Barriers - Fences Considerations: barriers blend Where appearance is a factor – other barriers can have same effect of wire fencing, yet blend better with overall appearance of facility. detract Fencing that will add and not detract from appearance. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
24
Concepts of Security Perimeter Barriers - Fences securitysurveys least cost When conducting security surveys most situations call for a recommend - dations that provide maximum protection at the least cost. Because of it’s relative low cost per running foot and the security it provides, a chain link fence is a common recommendation. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)

62
CONCEPTS of SECURITY “RISKS” Dynamic Risk:can produce profit or loss Dynamic Risk: (can produce profit or loss) a judgment call on the part of the businessman. Relate directly to business decisions. Pure Risk: Pure Risk: (No profit or potential for profit just loss). Risk of robbery, burglary, embezzlement, shoplifting, employee theft, Etc. ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
63
CONCEPTS of SECURITY (Continued) – “RISKS” Risk Management Risk Management: Attempts to reduce the possibilities for cost or loss in order to derive the highest possible net benefit. Risk Reduction : Risk Reduction : involves techniques to reduce potential for criminal confrontation. Risk Transfer: Risk Transfer: by using comprehensive insurance coverage risk of loss through criminal action is transferred from a business owner to insurance underwriter. See page 11 of your Concept of Security handout ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
64
Risk Elimination Risk Elimination: involves removing potential targets of dynamic or criminal risk (i.e. removing all cash from premise). Risk Spreading: may involve dividing potential targets into smaller segments thereby making a large loss les likely. (i.e. spread available cash around in several secured locations around premise). Risk Acceptance : business person assumes personally (see page 8 in your handout). CONCEPTS of SECURITY (Continued) – “RISKS” ©TCLEOSE Course #2101 Crime Prevention Curriculum Part I is the intellectual property of CSCS-ICJS (2009)
