Examples of types of physical access controls include all EXCEPT which of the following?

  1. badges
  2. locks
  3. guards
  4. passwords

Answer(s): D

Explanation:

Passwords are considered a Preventive/Technical (logical) control.
The following answers are incorrect:
badges Badges are a physical control used to identify an individual. A badge can include a smart device which can be used for authentication and thus a Technical control, but the actual badge itself is primarily a physical control.
locks Locks are a Preventative Physical control and has no Technical association. guards Guards are a Preventative Physical control and has no Technical association.

Guards are appropriate whenever the function required by the security program involves which of the following?

  1. The use of discriminating judgment
  2. The use of physical force
  3. The operation of access control devices
  4. The need to detect unauthorized access

Answer(s): A

Explanation:

The use of discriminating judgment, a guard can make the determinations that hardware or other automated security devices cannot make due to its ability to adjust to rapidly changing conditions, to learn and alter recognizable patterns, and to respond to various conditions in the environment. Guards are better at making value decisions at times of incidents. They are appropriate whenever immediate, discriminating judgment is required by the security entity.
The following answers are incorrect:
The use of physical force This is not the best answer. A guard provides discriminating judgment, and the ability to discern the need for physical force. The operation of access control devices A guard is often uninvolved in the operations of an automated access control device such as a biometric reader, a smart lock, mantrap, etc. The need to detect unauthorized access The primary function of a guard is not to detect unauthorized access, but to prevent unauthorized physical access attempts and may deter social engineering attempts.

What physical characteristic does a retinal scan biometric device measure?

  1. The amount of light reaching the retina
  2. The amount of light reflected by the retina
  3. The pattern of light receptors at the back of the eye
  4. The pattern of blood vessels at the back of the eye

Answer(s): D

Explanation:

The retina, a thin nerve (1/50th of an inch) on the back of the eye, is the part of the eye which senses light and transmits impulses through the optic nerve to the brain - the equivalent of film in a camerA. Blood vessels used for biometric identification are located along the neural retina, the outermost of retina's four cell layers.
The following answers are incorrect:
The amount of light reaching the retina The amount of light reaching the retina is not used in the biometric scan of the retina.
The amount of light reflected by the retina The amount of light reflected by the retina is not used in the biometric scan of the retina.
The pattern of light receptors at the back of the eye This is a distractor

Which is the last line of defense in a physical security sense?

  1. people
  2. interior barriers
  3. exterior barriers

Answer(s): A

Explanation:
