What is the role of access control systems in physical security?

• To identify and authenticate authorized users and deny unauthorized users

• To monitor and record the activities of users and intruders

  
  

• To provide physical barriers and obstacles to prevent or delay access

• To alert and notify the appropriate authorities or personnel in case of an incident

  
  

What are the three main types of security controls?

• Administrative, technical, and physical

• Preventive, detective, and corrective

  
  

•  Logical, operational, and environmental

•  Physical, logical, and environmental

  
  

What is the main purpose of preventive measures in physical security?

•  To reduce the likelihood of a threat occurring

• To increase the impact of a threat occurring

• To delay the response to a threat occurring

• To eliminate the possibility of a threat occurring

Which of the following is an example of a deter measure in physical security?

•  A lock on a door

  
  

• A sign warning of CCTV cameras

  
  

• A motion sensor alarm

• A fire extinguisher

  
  

 Which of the following is an example of a detect/react measure in physical security?

• A fence around a perimeter

•  A security guard patrolling an area

• A biometric scanner on an entrance

• A backup generator in case of power outage

What is the difference between physical security and cybersecurity?

• Physical security protects tangible assets, while cybersecurity protects intangible assets

• Physical security protects intangible assets, while cybersecurity protects tangible assets

• Physical security and cybersecurity protect the same assets, but with different methods

• Physical security and cybersecurity protect different assets, but with the same methods

What is the principle of defense in depth in physical security?

•  To use multiple layers of security controls to provide redundancy and resilience

  
  

•  To use the minimum amount of security controls to reduce complexity and cost

  
  

• To use the most advanced and sophisticated security controls to deter and defeat threats

• To use the same type of security controls to provide consistency and simplicity
