Improvements to SSL Security for whois.arin.net <br>
<br>
Thank you for your suggestion, numbered 2015.15 upon confirmed
receipt. Upon investigation, we discovered changing the
Diffie-Hellman (DH) key parameter is a configuration change that is
not currently supported by the vendor-supplied solution we use to
front our directory service applications. We are investigating our
options for this improvement with our vendor. We will make the
change once the vendor delivers a solution that is tested and proven
to work.<br>
<br>
As part of our third-party security audits, we require analysis and
reporting of our SSL-based services.<br>
<br>
Thank you for bringing this matter to our attention. This suggestion
will remain open until a solution is in place.<br>
<br>
