Explain the importance of physical security controls Flashcards
Bollards/barricades
A barricade is something that prevents access. As with any security system, no barricade is completely effective; a wall may be climbed or a lock may be picked, for instance.
Bollards are vehicle stopping polls
Access control vestibules
A mantrap, air lock, sally port or access control vestibule is a physical security access control system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens.
Badges
A photographic ID badge showing name and (perhaps) access details is one of the cornerstones of building security. Anyone moving through secure areas of a building should be wearing an ID badge; anyone without an ID badge should be challenged. Color-coding could be used to make it obvious to which zones a badge is granted access.
Alarms
Circuit—a circuit-based alarm sounds when the circuit is opened or closed, depending on the type of alarm.
Motion detection—a motion-based alarm is linked to a detector triggered by any movement within an area (defined by the sensitivity and range of the detector), such as a room.

Object detection
Motion recognition
Motion recognition—the camera system might be configured with gait identification technology. This means that the system can generate an alert when anyone moves within sight of the camera and the pattern of their movement does not match a known and authorized individual.
Object detection
Object detection—the camera system can detect changes to the environment, such as a missing server, or unknown device connected to a wall port.
Closed-circuit television (CCTV)
Installation of video cameras to supply security monitoring data to a centralized management station.
Industrial camouflage
Methods of disguising the nature and purpose of buildings or parts of buildings.

Two-person integrity/control
Reception areas for high-security zones might be staffed by at least two people at all times, providing integrity for entry control and reducing the risk of insider threat.

Cable locks
Devices can be physically secured against theft using cable ties and padlocks. Some systems also feature lockable faceplates, preventing access to the power switch and removable drives.
USB data blocker
Hardware plug to prevent malicious data transfer when a device is plugged into a USB charging point.

Faraday cages
A Faraday cage or Faraday shield is an enclosure used to block electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material, or in the case of a Faraday cage, by a mesh of such materials.
Air gap
Screened subnet (previously known as demilitarized zone)
Use a demilitarized zone design for the physical space. Position public access areas so that guests do not pass near secure zones. Security mechanisms in public areas should be highly visible, to increase deterrence.
