ISC2 CC Practice Question: Implements an access control system where users…
An organization implements an access control system where users are assigned to groups, and permissions are granted to groups rather than individuals. This is known as:
⚠ Common exam trap
ISC2 often tests the distinction between RBAC and ABAC by describing group-based assignment (RBAC) versus policy-based evaluation of multiple attributes (ABAC), leading candidates to confuse the two when the question mentions 'attributes' or 'policies'.

Correct answer & explanation
✓
Role-Based Access Control (RBAC)
Role-Based Access Control (RBAC) assigns permissions to roles (or groups) rather than to individual users. Users are then made members of these roles, inheriting the permissions associated with the role. This matches the description in the question, where users are assigned to groups and permissions are granted to those groups.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Mandatory Access Control (MAC)
Why it's wrong here
MAC enforces policies system-wide using labels, not group assignments.
- ✓
Role-Based Access Control (RBAC)
Why this is correct
RBAC uses roles/groups to manage permissions efficiently.
- ✗
Discretionary Access Control (DAC)
Why it's wrong here
DAC allows resource owners to set permissions, not necessarily group-based.
- ✗
Attribute-Based Access Control (ABAC)
Why it's wrong here
ABAC uses multiple attributes for access decisions, not just group membership.
Quick reference
Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
