Fix Recommendation

1. Create a .html file composed of the DoD-authorized warning banner verbiage:

"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."

2. Name the file "warning_banner.html".

3. Copy the .html file to the Tanium Server's http folder "<drive>:\Program Files\Tanium\Tanium Server\http\".

4. Using a web browser on a system that has connectivity to the Tanium application, access the Tanium application web UI and log on with multifactor authentication.

5. Click "Administration" on the top navigation banner.

6. Under "Configuration", select "Platform Settings".

7. Click "Create Setting".

8. Select "Server" box from "Setting Type".

9. In "Create Platform Setting" dialog box, enter "console_PreLoginBannerHTML" for "Name".

10. Select "Text" radio button from "Value Type".

11. Enter "warning_banner.html" for "Value:".

12. Click "Save".

Check Contents

1. Using a web browser on a system that has connectivity to the Tanium application, access the Tanium application web user interface (UI) and log on with multifactor authentication.

2. Verify the DoD use notification displays prior to login:

"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."

If a DoD-approved use notification banner does not display prior to logon or cannot be acknowledged before granting access, this is a finding.
