ISC2 CC Practice Question: Wants to implement a system that enforces access…
An organization wants to implement a system that enforces access decisions based on a user's attributes (e.g., department, clearance, time) and environmental conditions. Which model is best?
⚠ Common exam trap
ISC2 often tests the misconception that RBAC can handle dynamic conditions like time or location, but RBAC only maps users to roles with static permissions, whereas ABAC explicitly evaluates environmental attributes as part of the access decision.

Correct answer & explanation
✓
Attribute-based access control (ABAC)
Attribute-based access control (ABAC) is the correct model because it evaluates access decisions based on a combination of user attributes (e.g., department, clearance), resource attributes, and environmental conditions (e.g., time of day, location). Unlike RBAC, which relies solely on predefined roles, ABAC uses policies that can incorporate dynamic factors like current time or threat level, making it ideal for fine-grained, context-aware enforcement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Role-based access control (RBAC)
Why it's wrong here
RBAC uses static roles, not dynamic attributes.
- ✓
Attribute-based access control (ABAC)
Why this is correct
ABAC uses attributes and policies for fine-grained, context-aware decisions.
- ✗
Discretionary access control (DAC)
Why it's wrong here
DAC is based on owner discretion, not attributes.
- ✗
Mandatory access control (MAC)
Why it's wrong here
MAC uses fixed labels, not flexible attributes.
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 |
