I like people who are able to simplify things to others :)
Einstein said “If you can't explain it to a six year old, you don't understand it yourself.”
I agree to A, but authorization is misworded. Not "the tasks the user performs" which is actually the accounting function, but "the tasks the user is allowed to perform". It's different!
The correct answer is A. Authentication and authorization are two distinct processes in computer security:
Authentication: This process verifies the identity of a user or entity attempting to access a system or resource. It typically involves presenting credentials such as a username and password, digital certificates, or biometric information. The goal is to ensure that the user is who they claim to be.
Authorization: Once authentication is successful, authorization determines what actions or tasks the authenticated user is allowed to perform. It involves checking the user's privileges and permissions to access specific resources, perform certain operations, or execute particular commands. The goal is to control and limit the actions that a user can take within the system based on their authenticated identity.
So, authentication is about verifying the user's identity, while authorization is about controlling the user's access and actions within the system.
