Description
The security posture of the remote PC connecting to the enclave via VPN is vital to the overall security of the enclave. While on-site hosts are behind the enclave’s perimeter defense, a remote PC is not and therefore is exposed to many vulnerabilities existing in the Internet when connected to a service provider via dial-up or broadband connection. Though it is policy to have a firewall installed on the remote PC according to the Secure Remote Computing Endpoint STIG (SRC-EPT-405), it is imperative the VPN gateway enforce the policy to the software client to verify the firewall is active prior to enabling access to the VPN.
