- A
Mandatory Access Control (MAC)
Why wrong: MAC uses system-wide policies, not owner discretion.
- B
Discretionary Access Control (DAC)
DAC allows owners to set permissions.
- C
Attribute-Based Access Control (ABAC)
Why wrong: ABAC uses policies based on attributes, not owner discretion.

SSCP Access Controls Practice Question
This SSCP practice question tests your understanding of access controls. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which access control model allows the owner of a resource to determine who can access it and what permissions they have?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Discretionary Access Control (DAC)
Discretionary Access Control (DAC) gives resource owners discretion to grant or deny access to others.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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 uses system-wide policies, not owner discretion.
- ✓
Discretionary Access Control (DAC)
Why this is correct
DAC allows owners to set permissions.
Related concept
Standard ACLs match source addresses.
- ✗
Attribute-Based Access Control (ABAC)
Why it's wrong here
ABAC uses policies based on attributes, not owner discretion.
- ✗
Role-Based Access Control (RBAC)
Why it's wrong here
RBAC assigns permissions to roles, not to individual owner discretion.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
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 |
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SSCP ACL questions on filtering logic and placement.
