Access Control in Cloud Security for CompTIA Security Plus

What is Access Control?
Access Control is a security practice that regulates who or what can view, use or access a certain resource in a computing environment. It is a fundamental concept in security that minimizes risk to the system or data.
Importance of Access Control:
Access Control is important because it is a valuable security technique that can be used to control who or what can view or use any given resource. It protects system resources by limiting user access and provides a way to track user activity, which helps detect potential intrusions or misuse of information.
How Access Control works:
Access control performs its function by identifying users. This identification process involves the use of unique usernames and secure passwords. After the user is identified, access control policies are applied to determine what resources the user can interact with and the level of interaction permitted.
Exam Tips: Answering Questions on Access Control:
In answering questions on Access Control, ensure to clearly understand the question before writing your response. This can be achieved by taking time to read the question multiple times if necessary. Following this, apply the appropriate access control principle (e.g. least privilege, separation of duties or role-based access control). Demonstrate your understanding of the different access control models and when to use them. Examples can be discretionary access control (DAC), mandatory access control (MAC), or role-based access control (RBAC).
Conclusion:
Access control is a crucial part of cloud security that prevents unauthorized users from accessing sensitive data, helping businesses to prevent data breaches, and thereby maintain their reputation and customer's trust.
