Explanation:
Identification describes a method of ensuring that a subject (user, program, orprocess) is the entity it claims to be. Identification can be provided with the use of a username or account number. To be properly authenticated, the subject isusually required to provide a second piece to the credential set. This piece could be a password, passphrase, cryptographic key, personal identification number (PIN),anatomical attribute, or token. If the system determines that the subject may accessthe resource, it authorizes the subject.
