Objective
● Crime Prevention● Physical Access Controll● Video Survillance System● Fire Survilance System● Air conditioning● Electrial Solution● Mechanical Practices
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.
Threats to Physical Environment● Natural environmental threats
– Floods, earthquakes, storms and tornadoes, fires, extreme temperature conditions, and so forth
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.
Threats to Physical Environment● Manmade threats Unauthorized access (both internal and
external)– explosions, damage by angry employees, employee
errors and accidents, vandalism, fraud, theft
Threats to Physical Environment● Politically motivated threats
– Strikes, riots, civil disobedience, terrorist attacks, bombings, and so forth
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
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.
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)
Crime Prevention● Natural Surveillance
– personnel walkways– activity areas in ways that maximize visibility
● Make employees feel safe and intruders feel uncomfortable
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

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.
