Description
Display of a standardized and approved use notification before granting access to the virtual servers ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. System use notifications are required only for access via logon interfaces with human users and are not required when such human interfaces do not exist. This requirement applies to network elements that have the concept of a user account and have the logon function residing on the network element. The banner must be formatted in accordance with DTM-08-060. Use the following verbiage for network elements that can accommodate banners of 1300 characters: "You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only. By using this IS (which includes any device attached to this IS), you consent to the following conditions: -The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. -At any time, the USG may inspect and seize data stored on this IS. -Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose. -This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy. -Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details." Use the following verbiage for operating systems that have severe limitations on the number of characters that can be displayed in the banner: "I've read & consent to terms in IS user agreem't." This policy only applies to ALGs (e.g., identity management or authentication gateways) that provide user account services as part of the intermediary services.

If the BIG-IP Core does not provide user access control intermediary services for virtual servers, this is not applicable. When user access control intermediary services are provided, verify the BIG-IP Core is configured as follows: Verify Virtual Server(s) in the BIG-IP LTM module are configured with an APM policy to display the Standard Mandatory DoD-approved Notice and Consent Banner before granting access to the virtual servers. Navigate to the BIG-IP System manager >> Local Traffic >> Virtual Servers >> Virtual Servers List tab. Select Virtual Servers(s) from the list to verify. Verify under "Access Policy" section, that "Access Policy" has been set to use an access policy to display the Standard Mandatory DoD-approved Notice and Consent Banner. If the BIG-IP Core is not configured to display the Standard Mandatory DoD-approved Notice and Consent Banner before granting access to the virtual servers, this is a finding.
