Threat Analysis and Modeling Tool (TAM) tool is being retired inside Microsoft. It has been replaced with SDL Threat Modeling tool. It was my pleasure working with many folks internally and externally over this tool. In the interest of external customers who have adopted this tool, we are releasing the source code to MSDN code gallery which can be updated to add new features and fix any broken features. We have uploaded latest v3.0 beta source code which includes complete source code to GUI and web service along with SQL database scripts. The web service is used by GUI to download the meta data such as threats and countermeasures. I will be follow up with few more posts on how to develop on top on this source code.
