Discussion

Display of a standardized and approved use notification before granting access to the publicly accessible operating system 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. The banner must be formatted in accordance with applicable DoW policy. Use the following verbiage for operating systems 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." Satisfies: SRG-OS-000228-GPOS-00088, SRG-OS-000023-GPOS-00006, SRG-OS-000024-GPOS-00007

Check Content

Verify the operating system displays the required U.S. government notification banner prior to local or console logon.

1. Access the operating system using a privileged account and verify the ownership and permissions of the login banner file with the following command:

stat -c "%n %a %U %G" /etc/issue.d/10-SUSE

2. Verify the output shows:

/etc/issue.d/10-SUSE 600 root root

If the file does not exist, is not owned by root:root, or permissions are more permissive than 600, this is a finding.

3. Verify the banner contains the required warning text with the following command:

grep -i "U\.S\. Government" /etc/issue.d/10-SUSE

4. Review the returned banner content and verify it contains the approved U.S. government notification message.

If the required warning text is missing, altered, commented out, or the command returns no output, this is a finding.
