- A
Write denied
Why wrong: Write is not being attempted; the scenario specifically asks about read.
- B
Write allowed
Why wrong: Write is not the action in question; the star property (no write down) would apply, but the subject is attempting to read.
- C
Read denied
The subject's clearance is lower than the object's classification, so read is denied under the simple security property.
- D
Read allowed
Why wrong: The simple security property (no read up) prevents reading objects with higher classification.

SSCP Practice Question: Uses mandatory access control (MAC) with the…
This SSCP practice question tests your understanding of sscp exam topics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
An organization uses mandatory access control (MAC) with the Bell-LaPadula model. A subject has a clearance of 'Secret' and an object has a classification of 'Top Secret'. What is the result if the subject attempts to read the object?
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
✓
Read denied
In the Bell-LaPadula model, the Simple Security Property (no read up) prohibits a subject from reading an object with a higher classification. Since the subject has a clearance of 'Secret' and the object is classified as 'Top Secret', the read attempt is denied. This enforces mandatory access control (MAC) by preventing information flow from higher to lower security levels.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Write denied
Why it's wrong here
Write is not being attempted; the scenario specifically asks about read.
- ✗
Write allowed
Why it's wrong here
Write is not the action in question; the star property (no write down) would apply, but the subject is attempting to read.
- ✓
Read denied
Why this is correct
The subject's clearance is lower than the object's classification, so read is denied under the simple security property.

Read allowed
Why it's wrong here
The simple security property (no read up) prevents reading objects with higher classification.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the Bell-LaPadula model with the Biba model (which focuses on integrity) or misapply the *-property to read operations, leading them to incorrectly select 'Read allowed' or 'Write allowed' when the actual rule is 'no read up'.
Trap categories for this question
Scenario analysis trap
Write is not being attempted; the scenario specifically asks about read.
Detailed technical explanation
How to think about this question
The Bell-LaPadula model is a formal state machine model for enforcing MAC, primarily focused on confidentiality. It defines two key properties: the Simple Security Property (ss-property) which states that a subject at a given security level cannot read an object at a higher level (no read up), and the *-property (star property) which states that a subject cannot write to an object at a lower level (no write down). In practice, this model is used in multilevel secure (MLS) systems, such as those handling classified military data, where a Secret-cleared user cannot read Top Secret documents, preventing unauthorized disclosure.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. 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 |
