Fix Recommendation

Configure the Symantec ProxySG Management Console, SSH, and serial port to display the Standard Mandatory DoD Notice and Consent Banner in accordance with DoD policy before granting access to the device. Use the following verbiage for applications that can accommodate banners of 1300 characters:

"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."

Use the following verbiage for operating systems that have severe limitations on the number of characters that can be displayed in the banner:
"I've read & consent to terms in IS user agreem't."

To create an SSH logon banner:
1. Log on to the ProxySG Web Management Console, click "Configuration," then "Authentication," then "SSH Inbound Connections".
2. Enter the desired banner text into the "SSHv2 Welcome Banner" field, click "Apply".

To create a web user interface banner:
1. Log on to the ProxySG Management Console.
2. Create a reverse proxy service for the Notice and Consent banner.
3. Create the banner policy for the reverse proxy service realm using Visual Policy Manager.

To create a banner for the serial port:
1. Log on to the Command Line Interface (CLI).
2. Enter privileged mode.
3. Enter the following commands:

#(config)serial-console
#(config serial-console)inline pre-authentication-terms EOF
<Add the banner line by line exactly as stated with no changes.>
EOF

Check Contents

Verify the Standard DoD Banner is displayed:

1. Log on to the Web Management Console of the Symantec ProxySG and confirm that a banner is displayed that complies with the DoD requirement.
2. SSH into the command line interface of the Symantec ProxySG and confirm that a banner is displayed that complies with the DoD requirement.
3. Connect a computer to the serial port of the appliance and confirm that the DoD banner is displayed.

If Symantec ProxySG does not display the Standard Mandatory DoD Notice and Consent Banner before granting access to the device, this is a finding.
