Question 88

Explanation

The correct answer: Access control determines which users have access to specific resources, while authentication verifies that a user is who they claim to be: This answer accurately describes the differences between access control and authentication. Authentication is a process by which a system validates a user's identity. This typically involves a user providing some form of credentials, like a username and password, which the system checks against a database of authorized users. If the credentials match, the user is authenticated. Access control, on the other hand, determines what an authenticated user can do within a system. This can include accessing specific resources, performing certain tasks, and more. Access control rules or policies are typically set up by an administrator to enforce what different users or user roles can do within a system. Hence, while authentication is about verifying who a user is, access control is about deciding what they can do. The incorrect answers: Access control is focused on protecting systems from unauthorized users, while authentication is focused on verifying the identity of users: While it is true that access control is about protecting systems from unauthorized use, it's not merely focused on preventing unauthorized users from accessing the system. It also manages what authenticated (authorized) users can do within a system. Similarly, authentication is indeed about verifying the identity of users, but this process serves as the basis for both preventing unauthorized access and enabling access control. Access control is a proactive measure to prevent cyber attacks, while authentication is a reactive measure to identify and respond to cyber attacks: Both access control and authentication are proactive measures designed to prevent unauthorized access and, by extension, cyber attacks. Neither of them are primarily reactive measures for identifying and responding to cyber attacks. While authentication and access control logs can be used to help respond to a cyber attack after it has occurred, their primary purpose is to prevent unauthorized access before it happens. Access control and authentication are two different names for the same thing: As explained above, authentication and access control are two different, but related, security processes. Authentication is about verifying a user's identity, and access control is about controlling what that user can do once their identity is verified. They are not the same thing, even though they often work together in a comprehensive security framework.
