CERN Celebrates 20 Years of The Free And Open Web (Featured Blog)

Of all the many applications and services that run on top of the Internet, arguably none has been more successful than that of the World Wide Web. Invented by Tim Berners-Lee back in 1989 while he was a physicist at CERN, the "Web" has fundamentally changed almost every aspect of our life... and become a part of basically every aspect of our life. Think of a part of your life... and then think of the websites that are part of that. More...

FIR Podcast Hits Episode #700 – Publishes Special Interview With Shel and Neville

As most readers probably know by now, I'm been a weekly contributor to the "For Immediate Release (FIR)" podcast since back in 2005, and all those years later I continue to find the FIR episodes extremely useful ways to stay up on what is going on with social media, marketing, PR, podcasting and the intersection of all of those topics along with technology and business.

Last week Shel Holtz and Neville Hobson, the FIR co-hosts, passed the tremendous milestone of FIR episode #700. It's a pretty remarkable achievement to publish 700 instances of anything... but of a 60-90 minute podcast, week after week after week, is pretty amazing.

Shel and Neville tried to keep the actual FIR episode #700 to be fairly "regular" in terms of content, but at a suggestion from the FIR Google+ Community, they did allow themselves to be interviewed by Donna Papacosta about the show. Both the show and the interview are well worth listening to, in my opinion.

Congratulations, Shel and Neville, on publishing 700 episodes of FIR! Now I'm looking forward to the next 700 episodes...

Can DNSSEC and DANE Help Make Voice-over-IP (VoIP) and Unified Communications (UC) More Secure?

Can DNSSEC help make voice and video communications over IP more secure?  Could DNSSEC combined with DANE provide a means to more easily distribute the TLS/SSL certificates needed for VoIP phones and systems?  Can DNSSEC help ensure that you are talking with the correct VoIP system or application server?  Can DNSSEC improve the security of the many WebRTC-based clients being developed? How can a DNS-based public key infrastructure (PKI) help improved the security of IP-based communications?  (whether you call it “VoIP”, “unified communications”, “real-time communications” or just simply “telecommunications”)

These were among the questions that I set out to address in a presentation at the SIP Network Operators Conference (SIPNOC) 2013 last week in Reston, Virginia. Speaking to network operators ranging from large carriers and telcos to smaller “over-the-top (OTT)” startups, I used this set of slides to frame the discussion:

I also spoke about how two VoIP software products have already incorporated DNSSEC – the Jitsi softphone and the Kamailio server – and mentioned the new “DNSSEC and IP-based Communications” resource page I’m starting to build (and for which I would appreciate any suggestions).

I don’t necessarily have the “answers” to these questions (although I have opinions :-) )… I was more starting to raise the questions. The DNS community has been building this mechanism (DNSSEC) that provides a “trust layer” and can increase the security of DNS, as well as, via DANE, the entire TLS/SSL certificate infrastructure that we have come to rely upon.  How can we use these improvements to increase the security of IP communications?

For some further context, you may be interested in this recording I made on the topic:

I think there could be some good potential benefit here – and I’m looking forward to further discussions on this topic in the weeks and months ahead.  I’d love to hear your thoughts… either as comments to this post on our site or in social networks … or via direct email to me.

How could we use DNSSEC to increase the overall security of our communications infrastructure?


P.S.  I’ll also be appearing on the VoIP Users Conference (VUC) podcast on this coming Friday, May 3, 2013, to discuss these ideas within that community (to which anyone is welcome to join in). More details soon… 

Comcast Launches IPv6 Trials For Business Customers – Sign Up Today

comcast business logoWe were very pleased to see news yesterday on Comcast’s corporate blog about the launch of IPv6 services for businesses. Comcast’s John Jason Brzowski wrote there that:

  • Business Ethernet customers have had full IPv6 service and support in place for them since the beginning of 2013.

  • IPv6 trials are about to get underway for our Business Internet customers and we hope to launch full support shortly after completing the trials. Customers interested in signing up to participate in the trials can do so at http://www.comcast6.net/index.php/commercial-broadband-ipv6-form.

It is excellent to see Comcast offering these trials to their business users and we look forward to hearing of the success of those trials and the move to full IPv6 support.  Congrats to the team at Comcast for getting to this point.

If you are a Comcast Business customer, now is a time when you can sign up and get started with ensuring that your networks work fine with IPv6.   Why wait?
