AC-09 Previous Logon Notification

Control

Notify the user, upon successful logon to the system, of the date and time of the last logon.

Discussion

Previous logon notification is applicable to system access via human user interfaces and access to systems that occurs in other types of architectures. Information about the last successful logon allows the user to recognize if the date and time provided is not consistent with the user’s last access.

Assessment Objective

the user is notified, upon successful logon to the system, of the date and time of the last logon.

Assessment Method

Examine

Access control policy procedures addressing previous logon notification system design documentation system configuration settings and associated documentation system notification messages system security plan other relevant documents or records

Interview

System/network administrators organizational personnel with information security responsibilities system developers

AC-09(04) Additional Logon Information	Control Notify the user, upon successful logon, of the following additional information: [Assignement: additional information]. Discussion Organizations can specify additional information to be provided to users upon logon, including the location of the last logon. User location is defined as information that can be determined by systems, such as Internet Protocol (IP) addresses from which network logons occurred, notifications of local logons, or device identifiers. Assessment Objective the user is notified, upon successful logon, of [Assignement: additional information].
