Title

The operating system must display the DoD approved system use notification message or banner before granting access to the system for general system logons. (Cat III impact)

Discussion

Warning messages inform users who are attempting to log in to the system of their legal status regarding the system and must include the name of the organization that owns the system and any monitoring policies that are in place. As implementing a logon banner to deter inappropriate use can provide a foundation for legal action against abuse, this warning content should be set as appropriate.

Check Content

Review the contents of these two files and check that the proper DoD banner message is configured. # cat /etc/motd # cat /etc/issue If the DoD-approved banner text is not in the files, this is a finding.

Fix Text

The root role is required. Edit the contents of these two files and ensure that the proper DoD banner message is viewable. # pfedit /etc/motd # pfedit /etc/issue The DoD required text is: "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.
