The April 2009 edition of Messaging News Magazine is out, with my article entitled Security Threats in Collaboration Platforms (starting on page 16):

“Like beauty, you want security over collaboration platforms to be much more than skin deep. Security must be designed from the ground up, not treated as an after-thought. With an increasing volume of business conversations and transactions being communicated, coordinated and managed through collaboration tools, security is paramount. For the purpose of this article, we are considering collaboration platforms like Microsoft SharePoint, 37signals Basecamp, Traction Software Team Page, and others. We’re not looking at email, but rather tools that provide a separate “space” for an authorized group of people to share documents, track tasks, coordinate meetings, and manage the other details of a joint project.“
