Explanation
Non-repudiation refers to the principle that a message sender cannot deny sending a message or altering its content after sending it (see ISC2 Study Guide, Module 1, under Non-repudiation). Integrity ensures that the message has not been tampered with or altered during transit but does not provide proof of the sender's identity. Authentication, on the other hand, refers to the process of validating the identity of a user, system, or device--it is the act of confirming a claim of identity. Authorization refers to access control. It determines an authenticated user's permission to do something or access certain resources. However, neither authentication nor authorization can prevent a user from denying having sent a message.
