PSP Access Control Systems 3

Question 1

What does OSDP (Open Supervised Device Protocol) provide that legacy Wiegand does NOT?

Accepted Answer

Encrypted, bidirectional communication between reader and controller

Answer

OSDP provides AES-128 encrypted, bidirectional communication that enables mutual authentication between reader and controller, eliminating eavesdropping and relay attacks possible with Wiegand.

Question 2

Which US federal regulation mandates specific access control requirements for facilities handling classified national security information?

Accepted Answer

ICD 705 (Intelligence Community Directive 705)

Answer

ICD 705 establishes the physical and technical security standards for Sensitive Compartmented Information Facilities (SCIFs), including strict access control requirements.

Question 3

A security manager notices that access logs show an employee's card being used to enter a server room while the same employee is simultaneously badged into the main lobby. This is BEST described as:

Accepted Answer

A duplicate credential or card cloning incident

Answer

Simultaneous use of a credential at two locations indicates either a cloned card or a duplicate credential issued to an unauthorized person.

Question 4

What is the primary security advantage of using a 'credential + PIN' (something you have + something you know) access control system?

Accepted Answer

It provides multi-factor authentication, reducing risk from stolen or cloned credentials

Answer

Combining a physical credential with a PIN provides two-factor authentication, so a stolen or cloned card alone is insufficient to gain access.

Question 5

When performing an access control audit, which activity BEST identifies 'ghost accounts' (credentials belonging to former employees)?

Accepted Answer

Reconciling the active credential list against current HR employee records

Answer

Reconciling active credentials against current HR records identifies credentials that belong to terminated, transferred, or otherwise ineligible individuals.
