SIP, Unified Communications (UC) and Security
At the Ingate Systems SIP and Unified Communications Workshop in Los Angeles on October 4, 2010, Dan York gave this overview of the security issues facing unified communications systems and other VoIP systems based on the SIP protocol. He covered many of the topics discussed in his book, the "Seven Deadliest Unified Communications Attacks" - http://www.7ducattacks.com/

Using Git Submodules (to build a USB key distro, in this case)
As noted previously, I’m a huge fan of git and an avid user of Github. Given that, I appreciate learning new ways to do cool things with git. Here was a new one to me – using git “submodules” to build a package consisting of other git repositories. In this case, Adam Kalsey wrote about how he used the “git submodule” command to package up a number of different components for a USB key drive.
The key point is: each of the components remains in its OWN git repository – yet the overall “package” is ALSO under git revision control.
This is cool to me as I’ve wanted to do something similar in the past – I’ve now added “git submodule” to my internal “git toolbox” list. Looking forward to trying it out at some point.

Want to see what I’m working on? Follow me on Github…
If you want to track what I’m working on for programming projects these days, the best place to go is my Github account at:
If you are also a Github user (and accounts are free), you can simply “follow” me so that my updates appear in your Github “News Feed”. Or, you can simply go back to that page from time to time. 🙂
I am a big fan of the Git version control system and I do use git for pretty much all my coding projects right now… and generally link all the public projects into Github.

Welcome to Code.DanYork.com!
Welcome! Â You’ve found your way to yet-another-blog maintained by Dan York. When I recently did a count, I actively write on about 14 different blogs, most of which I list here.
So why start yet another place to write?
Well, the simple answer is that I want some place to write about programming, open source software, git, Tropo and so much more. Â Unfortunately that doesn’t really fit in with my main blogs of Disruptive Telephony, Disruptive Conversations or my main DanYork.com. Â I do have sites like Voxeo Developers Corner and the Tropo Blog where I can – and will – be writing… but those sites are targeted more toward services from Voxeo, the company I work for. Â I want a place to write about development in general.
I sort of have that now with my Advogato account, but Advogato is pretty much the same system it was six years ago… no comments, no auto-posting to Twitter or Facebook… I want to write about coding in a more modern CMS.
So I’m here… and odds are that I’ll be importing this feed back into Advogato. 🙂
I’m still tweaking the site… messing around with the theme and CSS… so it will change. Â Stay tuned for more…

ClueCon2009: The Security Saga of SysAdmin Steve
This is a story of VoIP security, a disgruntled employee and the trouble that can be caused in an unsecured environment. The presentation is done in a minimalist style popularized by Professor Lawrence Lessig. The 248 slides were presented in about 15 minutes at ClueCon 2009 in Chicago on August 5, 2009. A video recording will be made available and an update will be posted here. Do note that I did give an older version of this talk at ETel 2007 as "The Black Bag Security Review".
