During the information gathering stage of a deploying role-based access control model, which of the
following information is MOST likely required?

A.
Conditional rules under which certain systems may be accessed

B.
Matrix of job titles with required access privileges

C.
Clearance levels of all company personnel

D.
Normal hours of business operation

Explanation:
Role-based access control is a model where access to resources is determines by job role rather than by
user account.
Within an organization, roles are created for various job functions. The permissions to perform certain
operations are assigned to specific roles. Members or staff (or other system users) are assigned particular
roles, and through those role assignments acquire the computer permissions to perform particular
computer-system functions. Since users are not assigned permissions directly, but only acquire them
through their role (or roles), management of individual user rights becomes a matter of simply assigning
appropriate roles to the user’s account; this simplifies common operations, such as adding a user, or
changing a user’s department.
To configure role-based access control, you need a list (or matrix) of job titles (roles) and the access
privileges that should be assigned to each role.
Incorrect Answers:
A: For role-based access control, you don’t need conditional rules under which certain systems may be
accessed; you just need a list of roles and their associated privileges.
C: Clearance levels of all company personnel. Privileges are assigned based on job role rather than directly
to individuals.
D: The hours of business operation are not required. Business hours are not related to assigning access
privileges.
