Site and Facility Security Flashcards
Site and Facility
Site - Geographic area with a building
Facility - Building or part of the building
Fair Securely Vs. Fail Safe
Fail Securely: when there is a power failure, doors get locked automatically to secure the assets
Fail Safe: think about human life first during power failure
Site planning threats
- Natural environmental threats
- Supply Systems threats
- Manmade threats
In all situations, the primary consideration, above all else, is that nothing should impede ___________ goals
Life Safety
Protecting human life is the first priority
An Organization’s physical security program should address the following goals:
- Crime and disruption prevention through deterrence
- Reduction of damage through the use of delaying mechanisms
- Crime or Disruption detection
- Incident assessment
- Response procedures
Crime Prevention Through Environmental Design (CPTED)
Is a discipline that outlines how the proper design of a physical environment can reduce crime by directly affecting human behaviour
Crime Prevention Through Environmental Design (CPTED) and Target hardening are 2 different approaches
-Target hardening focuses on denying access through physical and artificial barriers (alarms, locks, fences, and so on)
4 main strategies of Crime Prevention Through Environmental Design (CPTED)
- Natural Access Control
- Natural Surveillance
- Territorial Reinforcement
- Maintenance
CPRED: Natural Access Conrol
Is the guidance of people entering and leaving a space by the placement of doors, fences, lighting, and even landscaping.
CPRED model shows how security zones can be created. Environment’s space should be divided into zones and the associated risks….labeling
Controlled
Restricted
Public
Sensitive
The goal of Natural Surveillance
Is to make criminals feel uncomfortable by providing many ways observers could potentially see them and to make all other people feel safe and comfortable by providing an open and well-designed environment
CPRED: Territorial Reinforcements
Which creates physical designs that emphasize or extend the organization’s physical sphere of influence so legitimate users feel a sense of ownership of that space.
CPRED: Maintenance
It basically states that criminals will be more attracted to facilities that look unkept because they’ll assume that the occupants don’t care as much about them and probably lack the resources to properly maintain and secure them.
Internal Partition should not be used…
In Protected areas that house sensitive systems and devices because they would limit the ability to detect malicious activity on those systems.
Clean Power supply no interference or voltage fluctuation. Possible type of line noise (2 interference)…
- Electromagnetic Interference (EMI)
- Radio Frequency Interference (RFI)
Voltage Fluctuations: Power excess
- Spike - Momentary high voltage
- Surge - Prolonged high voltage
Voltage Fluctuations: Power loss
- Fault: Momentary power outage
- Blackout: Prolonged, Complete loss of electric power
Voltage Fluctuations: Power Degradation
- Sag|dip: Momentary low-voltage condition, from one cycle to a few seconds
- Brownout: Prolonged power supply that is below normal voltage
- In-Rush Current: Initial surge of current required to start a load
Get clean and smooth distribution of power can be obtained by using:
- Voltage Regulator
- Line Conditioners
Components affected by Specific Temperatures
175F: Computer system and peripheral devices
100F: Magnetic Storage Devices
350F: Paper Products
Plenum Areas
Space above dropped Ceilings, the space in wall cavities, and the space under raised floors.
Water Sprinklers: Wet Pipe
(Aka Closed-Head system)
System always contain water in the pipes and are usually discharged by temperature controlled sensors.
Water Sprinklers: Dry Pipe
The water is not actually held in the pipes. Water is contained in a holding tank until it is released
Water Sprinklers: Precaution
Precaution systems are similar to dry pipe systems in that the water is not held in the pipes, but is released when the pressurized air within the pipes is reduced
Water Sprinklers: Deluge
System has its sprinkler heads wide open to allow a larger volume of water to be released in a shorter period.
What is used to measure humidity
Hygrometer
