Explain the importance of physical security controls Flashcards

1
Q

Bollards/barricades

A

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

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.

Q

Badges

A

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.

Q

Alarms

A

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.

Q

Motion recognition

A

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.

Q

Two-person integrity/control

A

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.

Q

Cable locks

A

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.

Faraday cages

A

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.

Q

Screened subnet (previously known as demilitarized zone)

A

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.
