Explanation:
“Identification is the act of a user professing an identity to a system, usually in the
form of a logon ID to the system.” Pg 49 Krutz The CISSP Prep Guide.
“Identification describes a method of ensuring that a subject (user, program, or process) 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 is usually 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.” Pg 110 Shon Harris: All-in-One CISSP Certification
