Question

Which access control model can dynamically assign roles to subjects based on a set of defined rules?

a. role based access control
b. mandatory access control
c. rule based access control
d. discretionary access control

Answer 1

Rule-based access control (RBAC) dynamically assigns roles to subjects based on predefined rules, factoring in conditions such as location or time.

Step-by-step explanation:

The access control model that can dynamically assign roles to subjects based on a set of defined rules is known as rule-based access control (RBAC). Unlike other models, RBAC can automatically assign user roles and execute permissions depending on the rules which may consider factors like time of access, the location of the user, and the state of the system among other conditions. For example, in a rule-based access control system, an employee might only be given access to certain network resources during their regular working hours.
