Also, we designed the tool with non-security experts in mind, making threat modeling easier for all developers by providing clear guidance on creating and analyzing threat models. Visit the Threat Modeling Tool to get started today! To better help you formulate these kinds of pointed questions, Microsoft uses the STRIDE model, which categorizes different types of threats and simplifies the overall security conversations.

A few minutes later, Ashish and Ricardo got into an extended discussion of how the Web server was built.
It was not the ideal way for a meeting to proceed, but everyone eventually agreed that discovering the discrepancy early was going to save them time in the future. In the second meeting, the team walked through the threats, discussed some ways to address them, and signed off on the threat model.
They checked the document into source control and continued with development. Some readers who have threat modeled may notice that we haven't talked about assets at all. We've discovered that many software engineers understand their software better than they understand the concept of assets and what assets an attacker may be interested in. If you're going to threat model a house, you might start by thinking about your family, irreplaceable photos or valuable artwork.
Perhaps you might start by thinking about who might break in and the current security system. Or you might start by considering the physical features, like the pool or the front porch. These are analogous to thinking about assets, attackers, or software design. Any of these three approaches work. The approach to threat modeling we've presented here is substantially simpler than what Microsoft has done in the past. We found that the software design approach works well for many teams.

Michael describes threat modeling like this: One of the most valuable and important SDL practices is threat modeling which is a systematic way to find design-level security and privacy weaknesses in a system. To help make threat modeling a little easier, Microsoft offers a free SDL Threat Modeling Tool that enables non-security subject matter experts to create and analyze threat models by: Communicating about the security design of their systems Analyzing those design for potential security issues using a proven methodology Suggesting and managing mitigations for security issues This tool builds on activities that all software developers and architects are familiar with—such as drawing pictures for their software architecture.
