Explanation:
“Identification is the process by which a subject professes an identify and accountability is initiated.”
Pg 149 Tittel: CISSP Study Guide “Identification and authentication are the keystones of most access
control systems. Identification is the act of a user professing an identify to a system, usually in the
form of a log-on ID to the system. Identification establishes user accountability for the actions on the
system. Authentication is verification that the user’s claimed identity is valid and is usually
implemented through a user password at log-on time.” Pg 36 Krutz: The CISSP Prep Guide
