All of the Above Explanation: • Authentication, verifies a user’s identity so only valid users can enter the system. • Authorization, after identity is established, checks what that user is permitted to do. • Encryption, converts readable data into an unreadable form so that intercepted or stolen data cannot be understood without the proper key. Together, these techniques ensure that only legitimate users can access data, that they can access only what they are allowed to, and that the data remains confidential if it is intercepted.
