The answer is Role-Based Access Control (RBAC). This model is best suited for department-based access in a small business because it maps permissions directly to job functions—such as HR or Finance—rather than to individual users, which keeps administration simple and scalable. When an employee changes departments, the administrator merely updates their role assignment, and all associated permissions are automatically applied or revoked, eliminating the need to reconfigure each user’s rights. On the Systems Security Certified Practitioner SSCP exam, this question tests your understanding of how RBAC aligns with organizational structure and ease of administration, often contrasting it with Discretionary Access Control (DAC) or Mandatory Access Control (MAC). A common trap is choosing DAC because it seems simpler, but RBAC’s role-based grouping is actually more efficient for department-level access. Memory tip: think “Role = Department” to remember that RBAC ties permissions to job functions, not individuals.
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.
A small business wants to implement an access control system where employees can access files based on their department (e.g., HR, Finance). They want simplicity and ease of administration. Which access control model is BEST suited?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Why wrong: MAC uses security labels and clearance levels, which is too rigid and complex for this simple department-based requirement.
B
Attribute-Based Access Control (ABAC)
Why wrong: ABAC uses multiple attributes (e.g., department, time, location) and can be more complex than needed for this simple requirement, though it could work.
C
Discretionary Access Control (DAC)
Why wrong: DAC allows users to set permissions on their own objects, which does not enforce department-based access and can lead to inconsistent rules.
D
Role-Based Access Control (RBAC)
RBAC assigns permissions to roles, and users are assigned roles based on their department, providing a straightforward and manageable solution.

Correct answer & explanation
✓
Role-Based Access Control (RBAC)
Role-Based Access Control (RBAC) is best suited because it maps access permissions directly to job functions (roles) such as HR or Finance, rather than to individual users. This simplifies administration: when an employee changes departments, the administrator simply updates their role assignment, and all associated permissions are automatically applied or revoked. RBAC is designed for environments where access decisions are based on organizational roles, providing a balance of security and ease of management.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse RBAC with DAC because both involve user-based permissions, but RBAC centralizes control through roles while DAC delegates control to individual resource owners, making RBAC the correct choice for department-based access.
Detailed technical explanation
How to think about this question
Under the hood, RBAC typically implements a many-to-many relationship between users and roles, and roles and permissions, often stored in a directory service like LDAP or Active Directory. A key subtlety is the principle of role hierarchy, where senior roles inherit permissions from junior roles, but this must be carefully managed to avoid privilege escalation. In a real-world scenario, a small business using RBAC might define roles like 'HR_Manager' and 'HR_Staff', where the manager role inherits all staff permissions plus additional ones for sensitive employee records.

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.
