Review all USS tables referenced in BEGINVTAM USSTCP statements in the PROFILE.TCPIP file. Ensure the MSG10 text specifies a logon banner in accordance with DISA requirements. See required MSG10 content below:

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.

-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.

DOD requires that a logon warning banner be displayed. Within the TN3270 Telnet Server, the banner can be implemented through the USS table that is specified on a BEGINVTAM USSTCP statement. The text associated with message ID 10 (i.e., MSG10) in the USS table is sent to clients that are subject to USSTCP processing.

The IBM z/OS warning banner for the TN3270 Telnet server must contain the proper content of the Standard Mandatory DoD Notice and Consent Banner.
