Provide a Power-On Banner

Although it is not a direct preventative or detective control, a banner can be used for these reasons:

• Convey ownership.

• Warn users of the acceptible use of the server.

• Indicate that access or modifications to OpenBoot parameters is restricted to authorized personnel.

• Use the following commands to enable a custom warning message.

  {0} ok setenv oem-banner banner-message
  {0} ok setenv oem-banner? true

  The banner message can be up to 68 characters. All printable characters are accepted.
