From IPSec VPN Gateway Security Technical Implementation Guide
Part of The VPN gateway server does not enforce banner warning.
Associated with IA controls: ECSC-1
All software remote clients must present a DoD approved warning banner prior allowing access to VPN. The banner should warn any unauthorized user not to proceed. It also should provide clear and unequivocal notice to both authorized and unauthorized personnel that access to the network is subject to monitoring to detect unauthorized usage. Failure to display the required warning banner prior to logon attempts will limit the ability to prosecute unauthorized access and also presents the potential to give rise to criminal and civil liability for systems administrators and information systems managers.
Review all ISAKMP client configuration groups used to push policy to remote software clients and determine if the software client will display a DoD approved warning banner prior to allowing access to the VPN. Verify either Option A or Option B (for clients with character limitations) of the Standard Mandatory DoD Notice and Consent Banner is displayed at logon. The required banner verbiage follows and must be displayed verbatim: Option A 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. Option B If the client is incapable of displaying the required banner verbiage due to its size or the server is limited as to the banner to push to the client, a smaller banner must be used. The mandatory verbiage follows:“I've read & consent to terms in IS user agreem't.”
Configure the ISAKMP client configuration groups used to push policy to remote software clients to display a DoD approved warning banner prior to allowing access to the VPN.
