Ensure that prior to purchasing a TLS VPN, the system has the capability to require RSA key establishment.

| Description |
|---|
| NOTE: TLS 1.0 and later uses the ephemeral Diffie-Hellman key establishment method, but this does not meet the requirements of NIST SP 800-56A. NIST has granted a waiver from this requirement for systems using SSL until the end of 2010 and this may be extended indefinitely. However, the current requirement for SSL key establishment now and beyond 2010 is the RSA method. |
