Re: Important re dropping TLS 1.0 support (Reminder: Changes to Whois-RWS and RDAP Scheduled for 12 February 2020)

For people running public facing httpd, it is also worth noting that the
population of old browser useragents that don't understand TLS1.2 is under
half of one percent.

There's very little risk or impact these days to only accepting TLS1.2 in
Apache2 or nginx configuration everywhere.

NANOG Folks -

If you are using programmatic interfaces over TLS 1.0 to access
ARIN Whois-RWS or ARIN RDAP services, please pay particular attention to
this announcement.

Thanks!

As we originally announced on 15 October 2019, there will be a change made
to ARIN’s Whois-RWS and RDAP services on 12 February 2020. This change may
impact the way you interface programmatically with ARIN to query and
retrieve information from these services.

ARIN will no longer be supporting TLS 1.0 for Whois-RWS and RDAP services.
There are well-known security issues with this protocol. We will continue
to support TLS 1.1 and 1.2. Please make sure your client implementation
will support TLS 1.1 or 1.2. Read
https://datatracker.ietf.org/doc/draft-ietf-tls-oldversions-deprecate/
for further details.

Because these changes will be implemented in about 60 days, we recommend
that you review your clients that interface with the Whois-RWS and RDAP
services, and make any required configuration or code changes in advance of
this change. Both TLS 1.1 and TLS 1.2 are available now. We encourage you
to make these changes so you will have no operational impact when we
disable the vulnerable transport protocols.

So that you can plan your upgrades accordingly, we would also like to
inform you of future planned events for this service. We will be adding TLS
1.3 support to Whois-RWS and RDAP in the near future. We also anticipate
announcing end-of-service support for TLS 1.1, with another corresponding
120-day warning notice.

Mark Kosters
