Question 3

Which access control model assigns permissions based on a user's role within an organization rather than individual identity?

Accepted Answer

Role-Based Access Control (RBAC)

A reader wiring run exceeds the maximum recommended distance for Wiegand. The best solution is to:

Accepted Answer

Install a Wiegand signal booster or use OSDP over RS-485 instead

Accepted Answer

Two authorized individuals to both present credentials before access is granted
