Fix Recommendation

Ensure the BANNER statement in the FTP Data configuration file specifies an HFS file or z/OS data set that contains a logon Standard Mandatory DoD Notice and Consent Banner. The below banner is mandatory and deviations are not permitted except as authorized in writing by the DoD Chief Information Officer. The thrust of this new policy is to make it clear that there is no expectation of privacy when using DoD information systems and all use of DoD information systems is subject to searching, auditing, inspecting, seizing, and monitoring, even if some personal use of a system is permitted:

STANDARD MANDATORY DOD NOTICE AND CONSENT BANNER

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.

Check Contents

Refer to the FTP.DATA file specified on the SYSFTPD DD statement in the FTP started task JCL. The SYSFTPD DD statement is optional.

The search order for FTP.DATA is:
/etc/ftp.data
SYSFTPD DD statement
jobname.FTP.DATA
SYS1.TCPPARMS(FTPDATA)
tcpip.FTP.DATA

Examine the BANNER statement.

-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 BANNER statement in the FTP Data configuration file does not specify an HFS file or z/OS data set that contains the Standard Mandatory DoD Notice and Consent Banner, this is a finding.
