Chapter 10: Site and Facility Security Flashcards
CPTED
Crime Prevention Through Environmental Design; combines physical environment and sociology issues that surround it to reduce crime rates and fear of crime
Four strategies of CPTED
natural access control, natural surveillance, territorial reinforcement, maintenance
Natural access control
guiding people for entering and leaving spaces with placement of doors, fences, lighting, landscaping
Goal of natural surveillance
provide an open and well-designed environment where authorized personnel feel safe and comfortable and criminals feel uncomfortable by providing many ways observers could potentially see them
Territorial reinforcement
emphasize or extend the org’s physical sphere of influence by creating physical designs (walls, fences, landscaping) so legitimate users feel a sense of ownership
CPTED’s maintenance principle
deter criminal activity by making sites look well cared for; implying site personnel are more attentive, well resourced, and alert
target hardening
denies access through physical and artificial barriers (alarms, locks, fences)
primary power source
used in day-to-day operations
alternative power source
backup in case the primary source fails
smoke detectors
located on and above suspended ceilings, below raised floors, and in air ducts to provide maximum fire detection
A fire needs…
high temperatures, oxygen, and fuel
portable fire extinguishers within …
50 feet of electrical equipment and should be inspected quarterly
CO2
colorless, odorless, and potentially lethal substance because it removes the oxygen from the air to suppress fires
Windows
standard, tempered, acrylic, wired, laminated
CO2 fire extinguishers
to be used when electrical equipment is on fire; not in workspaces or gas or metal fires
Water sprinklers
very effective against wood and paper fires and safe for humans so good choice for use in workspaces; not for electric, gas, metal
landscaping and bollards
natural access control
pedestrian walkway
natural surveillance
sense of ownership of a property and tendency to protect it
territorial reinforcement
implementing locks, security guards, proximity devices
target hardening; not a component of CPTED
High humidity
can cause corrosion
low humidity
can cause excessive static electricity
Static electricity
can short out devices or cause loss of information
Fourth principle of CPTED
maintenance; deter criminal activity by making sites look well cared for
category of controls in physical security
deterrence, delaying, detection, assessment, and response; lighting is a control not a category of controls
shared responsibility in physical security
different orgs have services agreement; leasing office spaces and having landlord provide security in entry points
defense in depth for physical security
create concentric rings around your most critical resources; only certain individuals should have access to the executive spaces and possibly, data center floor unless there are other security controls in place
