Question 1

What is the purpose of electronic security systems (ESS)?

Accepted Answer

The purpose of electronic security systems (ESS) is to protect a wide variety of assets from various types of threats by using electronic sensors, cameras, and automated access control systems. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "Every day, on our military installations and DoD facilities, we protect a wide variety of assets from various types of threats." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 2

What principle should an effective ESS operate on?

Accepted Answer

An effective ESS should operate on the Detect, Delay, Respond Principle, which ensures that the time between detection of an intrusion and response by security forces is less than the time it takes for damage or compromise of assets to occur. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "This is referred to as the Detect, Delay, Respond Principle." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 3

What are the five steps of the risk management process in relation to ESS?

Accepted Answer

The five steps of the risk management process are: 1) Identify assets, threats, and vulnerabilities; 2) Conduct a risk analysis; 3) Develop countermeasures to address certain risks. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "This risk management process has five steps: identify assets, threats, and vulnerabilities, then conduct a risk analysis and develop countermeasures to address certain risks." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 4

What is the role of automated access control systems (AACS)?

Accepted Answer

The role of automated access control systems (AACS) is to interface with locking mechanisms to permit access to controlled areas after verifying entry credentials, ensuring that only authorized personnel can access those areas. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "An AACS is an automated system that interfaces with locking mechanisms to momentarily permit access to a controlled area." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 5

What are the three general types of automated access control systems?

Accepted Answer

The three general types of automated access control systems are coded devices, credential devices, and biometric devices. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "Automated access control systems fall into three general types: coded devices, credential devices, and biometric devices." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 6

What is one advantage and disadvantage of using coded devices for access control?

Accepted Answer

One advantage of using coded devices is that they are reliable, compact, and user-friendly. A disadvantage is that codes can be easily passed onto unintended visitors, posing security risks. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "Keypad devices are reliable, compact, user-friendly, and easy to maintain, repair, or replace." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 7

What feature should an AACS have to prevent unauthorized personnel from entering a controlled area?

Accepted Answer

An AACS should have the capability to log and archive all entry attempts and alert authorities of unauthorized entry attempts. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "An AACS can log and archive all entry attempts and entries made into a controlled area and can alert authorities of unauthorized entry attempts." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 8

What is the importance of life safety considerations in planning an AACS?

Accepted Answer

Life safety considerations are important because the access control system must accommodate free egress in emergencies, allowing people to exit quickly from controlled areas. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "In addition to planning for entry into a controlled space, you must also take into consideration how people will exit from that space in the event of an emergency." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 9

What is the purpose of the anti-passback feature in an AACS?

Accepted Answer

The anti-passback feature is implemented to mitigate the risk of someone giving their credentials to another person to access a controlled area. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "If so, then the AACS will require the anti-passback feature." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 10

What is the function of the two-person rule in an AACS?

Accepted Answer

The two-person rule prevents individual cardholders from entering a selected empty controlled area unless accompanied by at least one other person. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "Under the two-person rule, no individual cardholder may enter an empty controlled area unless accompanied by at least one other person." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]

Question 11

How does a biometric device function in an AACS?

Accepted Answer

A biometric device allows individuals access to a controlled area after they display a specific biological characteristic, which is compared to a stored characteristic for verification. [Source: CDSE — Electronic Security Systems (PY250.16) Student Guide — "Biometric devices allow individuals access to a controlled area after they display a specific biological characteristic into the device, which compares it to a stored characteristic." https://www.cdse.edu/Portals/124/Documents/student-guides/PY250-guide.pdf]
