Title
IBM z/OS FTP.DATA configuration statements must have a proper BANNER statement with the Standard Mandatory DoD Notice and Consent Banner. (Cat II impact)
Discussion
Display of a standardized and approved use notification before granting access to the operating system ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. System use notifications are required only for access via logon interfaces with human users and are not required when such human interfaces do not exist. Satisfies: SRG-OS-000023-GPOS-00006, SRG-OS-000024-GPOS-00007
Check Content
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. If the BANNER statement in the FTP Data configuration file specifies an HFS file or data set that contains a logon banner as specified below this is not a finding. 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. -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.
