Fix Recommendation

Create a text file containing the required DoD text.

Name the file "banner" and place it in "/etc/".

Check Contents

Verify the operating system displays the Standard Mandatory DoD Notice and Consent Banner before granting access to the operating system.

Check to see if the operating system has the correct text listed in the "/etc/banner" file with the following command:

# more /etc/banner

The command should return the following text:
"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 the operating system does not display a graphical logon banner or the banner does not match the Standard Mandatory DoD Notice and Consent Banner, this is a finding.

If the text in the "/etc/banner" file does not match the Standard Mandatory DoD Notice and Consent Banner, this is a finding.
