Guide to Access Controls for CompTIA Security+
Access controls are vital for maintaining the integrity, confidentiality, and availability of information in an IT setup.
They inherit the best practices from ISO/IEC 27000 series, specifically ISO 27001 and ISO 27002, defining the policies, procedures, organizational structures and software and hardware functions.
The purpose of access control is to prevent unauthorized access to organizational resources including data. Access Control works through a combination of identification, authentication, authorization, and accountability also known as IAAA.
When answering questions on Access Controls in an exam:
1. Understand the underlying principle you are asked to apply before you answer.
2. Remember the concept of least privilege: Always ensure the minimum privileges required to perform a function/duty.
3. Consider the context of the question: Is it about preventive, detective, corrective or deterrent controls?
4. Always remember the IAAA when answering questions on access control.
Exam Tip: In a CompTIA Security+ exam, real-world examples in situational questions on Access Control can help you determine the most secure and practical solution.

Access Controls practice test
Access controls are mechanisms that restrict access to resources and maintain the confidentiality, integrity, and availability of data within an application. These mechanisms are implemented through the use of access control lists (ACLs) and role-based access control (RBAC), where users are assigned roles and permissions that limit their interaction with the system based on the principle of least privilege. By controlling user access and authorization, organizations can ensure that only authorized users can perform specific tasks, reducing the risk of unauthorized access, data leaks, and tampering with sensitive data.
