For those curious, this show is a prime example of the "Long Tail" of content on the Web - even though we haven't produced a new "real" show since #85 on October 23, 2008, we still see anywhere from 30-100 downloads of various Blue Box shows every day.  People are finding the show through various search terms and listening to the episodes.  

Perhaps somewhat sadly this is also a commentary on how relevant some of the same VoIP security issues we discussed from 2005-2008 still are today in 2012!

My apologies, again, to anyone who tried listening over the past weekend when the show was offline.  Thank you for the interest and for I hope that you find our past episodes educational and useful.

If you are trying to listen to any of our old Blue Box shows, unfortunately it seems I missed an email alert and the payment method expired for the service I use to host the media files. I am in communication with their billing department now and expect to have the matter cleared up tomorrow with the shows available again.

My apologies to anyone who was trying to listen to one of the shows. I will get them back online as soon as I can.

In the book, I discuss the common theme that Jonathan and I have talked about on the show of needing to look at communications security at a higher-level, more "holistic" level. It's not enough just to think about the security of your IP-PBX... you also have to think about the security of your mail servers, your firewalls, your databases, etc.

You also have to think beyond voice to also including instant messaging/IM, video, presence, mobile devices and more. And... you have to think about them in the context of a globally-distributed IP infrastructure.

Information about the book and links to resources mentioned in the book are available from the books website:

www.7ducattacks.com

I have also posted links there to two podcast interviews I've done related to the book:

I am working on getting permission to run those both as Blue Box Special Editions (I have approval on the VUC session).

In many ways, much of the book came out of the three years of great conversations that Jonathan and I had with so many of you - and I have to thank all of you who have participated in the Blue Box community over the years for your questions, your comments and all the feedback. I hope you will find that this book continues that dialogue and discussion about how to secure our communications networks.

Last week at the Emerging Communications Conference (eComm) 2009 in San Francisco, a remarkable event happened: Jonathan Zar, Martyn Davies, and I (Dan York) all wound up at the same place at the same time. Over the 3.5 years since we started Blue Box back in October 2005, Jonathan and I have met at events, Martyn and I have met and Jonathan and Martyn have met. But the three of us had never been together at the same place.

Now the particular place we met was a "Dev Dinner" hosted by (my employer) Voxeo after the end of eComm - and we had some great conversations along with the food. Martyn produced his camera and we did record the actual event:

bluebox-at-ecomm2009.jpg

Alas, it was too noisy there for us to do any actual recording, but it was great to have all three of us there. For those who may not recall the history, Martyn was one of our earliest listeners and is the person who provided both the image that we use for Blue Box (in iTunes, in the MP3 file, etc.) and also the music that we use for the intro and outro. He's also guest-hosted several times and contributed a couple of interviews over the years.

P.S. And yes, Jonathan and I will be getting some more shows out...

The SIP trunking workshops are free to all attendees even if you only register for an exhibit pass.

My session will be 11:15-12:30 on Wednesday, February 3rd, and if you do attend please feel free to come up and introduce yourself (or drop me a note in advance to let me know to look out for you). I'll be bringing my recording gear, too, and the talk will eventually go out in my Blue Box Podcast feed so you will be able to hear it later.

P.S. If you are attending ITEXPO and your company makes a product or provides a service related to VoIP security, please feel free to let me know and perhaps we can schedule an interview to go out as a Blue Box Special Edition.

As Alan details on his blog, Google is in the process of shutting down the "Network" feature of Feedburner and as a result the page and feed for the SBN will be going away.

Alan is working on a new solution but in the meantime you may want to grab the OPML file for the Security Bloggers Network (you should then be able to import this into most feed readers). There are a lot of great security blogs out there.

Stay tuned for more information - once Alan has another solution in place I'll post an update. ]]>For those of you who may be used to reading this blog through the "Security Bloggers Network" set up originally by Alan Shimel, you need to be aware that the "SBN" is going through a transition.

I transferred blueboxpodcast.com from one registrar to another last week shortly before the domain name was set to expire. Unfortunately, I made one serious mistake - I didn't check the DNS nameservers for the domain at the new registrar (GoDaddy) to ensure they were pointing to the new nameservers. They weren't... they will still pointing to the old nameservers. As a result, when the domain name expired at the end of the day on Friday, the web site was no longer available and had the message that the domain name had expired.

MANY THANKS to the couple of you who contacted me on Saturday to let me know about this!

So I fixed the web site yesterday morning so that "www.blueboxpodcast.com" pointed over to TypePad, where I host this site, and that all seems to be back in action. If you type in "blueboxpodcast.com" without the "www", it was going to a generic GoDaddy page but I've set up the forwarding now so that this should now redirect you to www.blueboxpodcast.com once the DNS propagation occurs.

feedburnerlogo.jpgWhat is still dead, though, is the RSS feed... which is rather annoying since that is what podcast subscription tools like iTunes use! In working through the issues this morning, it appears to be the issue that

Feedburner is not using the updated DNS information.
The Blue Box RSS feed, which is http://feeds.feedburner.com/BlueBox is somehow pointing over to the old page. Yet the base feed for this site, http://www.blueboxpodcast.com/atom.xml resolves perfectly fine and does have the RSS information. (Please don't switch to subscribe to that one... I do like the stats I get through Feedburner.)

So it appears that I'm waiting for FeedBurner to update its DNS. I've tried all sorts of options in the FeedBurner settings, including the "Resync Feed" but nothing works because it seems that it is unable to get to the new site (because of DNS).

I've filed a help request in the FeedBurner Google Group (which appears to be the only way to get help). Hopefully FeedBurner will age out its DNS info soon and the feed will be back in action.

What I find strange, though, is that I'm 99% sure that all the DNS records had a TTL of 1 hour (and I'm 100% positive the new ones do). So my question to FeedBurner is - if that is the case, why aren't they respected the TTL settings of the domains?

I'll update this post once I have more information.

It was three years ago on October 24, 2005, that Blue Box Podcast #1 was uploaded. It was an 11-minute episode where I talked about... Skype security, SIP security, IETF, VOIPSA and some other VoIP security news..... (Hmmm... sounds lot like our recent shows, too, eh?)

Jonathan Zar joined me a week later on Blue Box Podcast #2 and we've been going ever since. We've now produced over 112 episodes, had close to 245,000 downloads of our various shows, met some amazing people, learned a lot along the way... and hopefully helped you all learn a lot out there as well.

Thank you to all of you who have joined with us on this journey... whether you've listened to our show from the very beginning (and we know of a couple of you who have) or have only recently joined in... thank you!

And now... on to the next three years... :-)

Three years later... 84 main Blue Box episodes (with one more recorded) .... 26 Special Editions (with about 10 in the queue)... almost 250,000 downloads... we're still here and, with an admitted bit of a rough patch this summer, are still going along creating shows and enjoying what we do.

Jonathan and I are planning to record a 3-year show on this coming Friday, October 24th, and if you have any comments you would like us to include in that show, please do get them to us by the end of the day on Thursday, October 23rd. You can send them to us via:

The show started out 3 years ago as really an experiment in seeing whether or not podcasting could be used to reach out to very specific audiences... and it's been both fun, amazing and interesting to see how well it's done.

Thank you to all of you who have continued to listen and contribute over the years!
