What defines an access control list (ACL)?

• A. A set of user passwords
• B. A database of network devices
• C. A set of rules governing user access to resources
• D. A security protocol for wireless networks

Answer: (C)

An access control list (ACL) is fundamentally defined as a set of rules that govern which users or systems have access to particular resources and what operations they can perform on those resources. This can include permissions such as reading, writing, or executing files or services. ACLs are commonly used in network security to control access to resources, such as files and directories, ensuring that only authorized individuals can access sensitive information or perform critical operations. In network devices, ACLs are also utilized to manage traffic control and enhance the security posture by allowing or denying the flow of traffic based on specified conditions, such as IP addresses or protocols. This structure is crucial for establishing a clear access framework within various environments, ensuring that protections are in place to prevent unauthorized access or misuse. In short, an ACL is designed specifically to articulate and enforce access controls, making option C the correct definition.
