The document discusses physical and environmental security, highlighting crime prevention, physical access control, fire surveillance systems, and HVAC considerations. It outlines various threats to physical environments, including natural disasters, supply system interruptions, manmade threats, and politically motivated risks. Additionally, it describes the design principles for enhancing security through natural access control, surveillance, and territorial reinforcement, as well as the classification of data center tiers based on redundancy and fault tolerance.

2. Objective
●
Crime Prevention
●
Physical Access Controll
●
Video Survillance System
●
Fire Survilance System
●
Air conditioning
●
Electrial Solution
●
Mechanical Practices

3. Physical Security
●
discuss about the threats, vulnerabilities, and
countermeasures that can be utilized to
– physical protect an enterprise’s resources
– and sensitive information.
●
covers designe to deny access to unauthorized personnel
(including attackers) from
– physically accessing a building, facility,
resources, or stored information;
●
and guidance on how to design structures to resist
potentially hostile acts.

4. Threats to Physical Environment
●
Natural environmental threats
– Floods, earthquakes, storms and tornadoes, fires,
extreme temperature conditions, and so forth

5. Threats to Physical Environment
●
Supply system threats
– Power distribution outages,
– communications interruptions,
– and interruption of other natural energy resources
such as water, steam, gas, and so on.

6. Threats to Physical Environment
●
Manmade threats Unauthorized access (both internal and
external)
– explosions, damage by angry employees, employee
errors and accidents, vandalism, fraud, theft

7. Threats to Physical Environment
●
Politically motivated threats
– Strikes, riots, civil disobedience, terrorist attacks,
bombings, and so forth

8. Physical Access Controll
●
Electronic Card
●
Biometric security
●
Access Level

9. Video Survilance
●
CCTV
●
DVR
●
IP Camera
●
Remote Access

10. Fire Survilance
●
Fire
– Cause : heating equipment, electrical panel, broken
ware, electrical extention
●
Fire Alarm System / Survilace System
– Detect fire element, like smoke, heat
– Locate fire ignition point
– Operate fire fighting equipment
– Initiate fire evacuation process and save life

11. HVAC
●
Heating, Ventilating and Air Conditioning
– Upflow , downflow and inrow
– Air volume cubic feet per
– minute (CFM) per ton.
– Humidity control (RH 45% - 60%).
– Temperature control (72°F ± 2°F).
– Air Filters.
– Positive air pressure.
– Protected intake vents.
– Alarms: Leak detection, loss of power,
– temperature, humidity, fire, smoke detector.

13. Crime Prevention
●
Natural Access Control
– Terrain
• Distance from fenced
boundary to building.
• Distance to adjacent
building or structure.
• Roadway and paths to
building(s).
– Landscaping
• Spiny shrubs and/or trees
• Grass, sod or gravel traps
• Water (i.e. drainage pond,
lake or stream)

14. Crime Prevention
●
Natural Surveillance
– personnel walkways
– activity areas in ways that maximize visibility
●
Make employees feel safe and intruders feel
uncomfortable

15. Crime Prevention
●
Territorial Reinforcement
– Physical designs that emphasize or extend the
company’s physical sphere of influence so that
legitimate users feel a sense of ownership of that
space
– Use walls, fences, flags, etc.
– Create a sense of dedicated community

16. Crime Prevention
●
Territorial Reinforcement
– Physical designs that emphasize or extend the
company’s physical sphere of influence so that
legitimate users feel a sense of ownership of that
space
– Use walls, fences, flags, etc.
– Create a sense of dedicated community

17. Data Center tier
●
Tier 1 = Non-redundant capacity components (single
uplink and servers).
●
Tier 2 = Tier 1 + Redundant capacity components.
●
Tier 3 = Tier 1 + Tier 2 + Dual-powered equipments and
multiple uplinks.
●
Tier 4 = Tier 1 + Tier 2 + Tier 3 + all components are
fully fault-tolerant including uplinks, storage, chillers,
HVAC systems, servers etc. Everything is dual-powered.
