Blue Box: The VoIP Security Podcast

Dan's new book: Seven Deadliest Unified Communications Attacks

For those of you listening to Blue Box, you may be interested to know that I (Dan) recently wrote a book for Syngress called the "Seven Deadliest Unified Communications Attacks". 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:

• Telecom Junkies
  
  
• VoIP Users Conference

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.

Blue Box's 3-year anniversary coming up on Friday...

It was three years ago Friday, on October 24, 2005, that I uploaded Blue Box Podcast #1, an 11-minute show where I introduced the show, talked about VoIP security news (To no surprise, I was talking about Skype security!), some projects of VOIPSA and some other podcasts people might find interesting. A week later, on Halloween 2005, Jonathan joined me in Blue Box Podcast #2 and we were off and running...

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:

• Email to [email protected]
• Phone to +1-415-830-5439
• Phone via SIP to sip:[email protected]

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!

Blue Box SE#026 - Astricon 2007 presentation on VoIP security and Asterisk

Show Content:

A year ago in September 2007, I (Dan York) spoke at Astricon 2007 in Arizona, USA, about "Hacking and Attacking VoIP Systems: What You Need To Worry About" My presentation covered a lot of the typical VoIP security threats, tools and best practices but also expanded a bit into specific security issues with Asterisk.  Please do keep in mind that it has been a year since this presentation and so some of the issues I mention have been addressed. (Astricon, for those who don't know, is an annual developer conference for those who work with the Asterisk open source telephony platform. Astricon 2008 is, in fact, coming up in about 3 weeks but I will not be attending this year.)

The slides for this talk are available from Slideshare:

Hacking and Attacking VoIP Systems - What You Need To Know

View SlideShare presentation or Upload your own. (tags: voip voipsecurity)

(And yes, at some point I'll sync the audio with the slides.)

Production assistance on this Special Edition was provided by Michael Graves who had a very tough task given the poor quality of the recording that I gave to him!  Kudos to Michael for getting it to sound as good as it does.

Show Content:

In this interview, I sat down with Eric Hernaez, CEO of Solegy, to talk about the OpenSBC Project and how it provides an open source implementation of a session border controller (SBC).  We talked about how OpenSBC came about, who is using it, how scalable it is and where users can learn more.  We also discussed Solegy, the company supporting the open source OpenSBC project and what they are doing. It was an enjoyable talk that really came about randomly when I met Eric near the press room at IT Expo in Los Angeles back in September 2007. We had been wanting to learn more about the OpenSBC project so I put my recorder on a table and we started talking.

More information about the OpenSBC project and other open source SIP-related projects can be found at opensourcesip.org.

Production assistance on this Special Edition was provided by Sergio Meinardi.
