AC-12: SESSION TERMINATION

  • FedRAMP Baseline Membership AC-12:
  • MODERATE
  • HIGH

FedRAMP Bracketology

Use the FedRAMP Control Membership information above to determine if a control or control enhancement is required for each Impact Baseline — LOW, MODERATE, or HIGH

Click on the panel below each control or control enhancement to review the FedRAMP Impact Baseline-specific control configuration requirements for each of the [BRACKETS] in each control and/or control enhancement.

Review and use Additional Requirements and Guidance to build FedRAMP-compliant controls for your risk-based cybersecurity program.

To change the baseline view in the panel, click on LOW, MODERATE, or HIGH when the panel is open

Panels only appear where there are [BRACKETS] in the control or enhancement or where there is FedRAMP-specific requirements or guidance available.

The information system automatically terminates a user session after [Assignment: organization-defined conditions or trigger events requiring session disconnect].

Click Low | Moderate | High below to see FedRAMP control configuration information. It's in BOLD.

There are no FedRAMP-specific requirements if this control is used for a Low Impact system.

There are no FedRAMP-specific requirements if this control is used for a Moderate Impact system.

There are no FedRAMP-specific requirements if this control is used for a High Impact system.

SUPPLEMENTAL GUIDANCE

This control addresses the termination of user-initiated logical sessions in contrast to SC-10 which addresses the termination of network connections that are associated with communications sessions (i.e., network disconnect). A logical session (for local, network, and remote access) is initiated whenever a user (or process acting on behalf of a user) accesses an organizational information system. Such user sessions can be terminated (and thus terminate user access) without terminating network sessions. Session termination terminates all processes associated with a user�s logical session except those processes that are specifically created by the user (i.e., session owner) to continue after the session is terminated. Conditions or trigger events requiring automatic session termination can include, for example, organization-defined periods of user inactivity, targeted responses to certain types of incidents, time-of-day restrictions on information system use.

CONTROL ENHANCEMENTS

AC-12 (1) SESSION TERMINATION | USER-INITIATED LOGOUTS / MESSAGE DISPLAYS
  • FedRAMP Baseline Membership AC-12 (1):
  • HIGH

The information system:

    • (a) Provides a logout capability for user-initiated communications sessions whenever authentication is used to gain access to [Assignment: organization-defined information resources]; and
    • (b) Displays an explicit logout message to users indicating the reliable termination of authenticated communications sessions.

There are no FedRAMP-specific requirements if this control is used for a Low Impact system.

There are no FedRAMP-specific requirements if this control is used for a Moderate Impact system.

AC-12 (1): Provides a logout capability for user-initiated communications sessions whenever authentication is used to gain access to [Assignment: organization-defined information resources]; No FedRAMP-specific requirements

Supplemental Guidance:

Information resources to which users gain access via authentication include, for example, local workstations, databases, and password-protected websites/web-based services. Logout messages for web page access, for example, can be displayed after authenticated sessions have been terminated. However, for some types of interactive sessions including, for example, file transfer protocol (FTP) sessions, information systems typically send logout messages as final messages prior to terminating sessions.
