The STRIDE methodology is an important one, and any means of raising awareness of threats with software developers is a good thing. Re-review of attack surface and threat models when the program is code complete to ensure security assumptions and mitigations specified at design time are still relevant. Step 3 (threat elicitation) is therefore the focus of this document. The SDL Threat Modelling Tool does a great job of making threat modelling (a process usually executed by dedicated security professionals) into a task that a huge number of software developers can execute. This document was actually used as baseline during a descriptive study (for the evaluation of LINDDUN). This document also illustrates the easy transition from the client-server diagram to the DFD required by LINDDUN.Īnother example involves a smart grid system that is being evaluated for privacy threats using LINDDUN. Note that in this example has been worked out using the original LINDDUN and thus not take into account the updated LINDDUN trees or the updated fifth step (mitigation strategies) of the methodology.Ī more extensive execution of LINDDUN is the step-by-step application of (the original) LINDDUN to a patient community system (steps 1-4).
The full running example is available in the LINDDUN paper. As a result, it greatly reduces the total cost of development. It allows software architects to identify and mitigate potential security issues early, when they are relatively easy and cost-effective to resolve. You can use threat modeling to shape your applications design, meet your companys. The Threat Modeling Tool is a core element of the Microsoft Security Development Lifecycle (SDL). It’s an engineering technique you can use to help you identify threats, attacks, vulnerabilities, and countermeasures that could affect your application. Microsoft Threat Modeling Tool 2016 Getting Started Guide Beta July 2016 SDL Policy & Tools Contents Document History Document Status: Approved Overview The Microsoft Threat Modeling Tool (TMT) 2016 is designed to guide you and your product team through the threat modeling process. These examples thus do not yet take into account the updated solution-oriented steps, nor do they consider the updated LINDDUN threat trees, as they closely follow the methodology and threat trees described in the original LINDDUN paper. Threat modeling is a core element of the Microsoft Security Development Lifecycle (SDL). Note that currently these examples are still based on the original LINDDUN methodology and LINDDUN threat trees.
SDL Threat Modeling Tool 3.1 beta is available for download here.Below you can find a number of worked out examples of the LINDDUN methodology. As an integral part of the initiative, Microsoft pointed developers to the SDL Pro Network, the SDL Optimization Model and the Microsoft SDL Threat Modeling Tool 3.0 as resources necessary to.
“Innovative features in the Microsoft SDL Threat Modeling Tool 3.0 include these: automation - guidance and feedback in drawing threat diagrams STRIDE Framework - guided analysis of threats and mitigations integration - bug-and issue-tracking systems reporting capabilities - security activities and testing in the verification phase,” Microsoft explained.Īccording to the Redmond company, the SDL Threat Modeling Tool, a core element of the Security Development Lifecycle, is set up to perform analysis on the designs and software architecture ahead of the implementation phase. Microsoft's strategy with sharing its security best practices, model and tools with third-party software developers is meant to counter the generalized trend of the threat landscape to focus on the software designed to run on top of the Windows operating system, as opposed to the actual platform, in terms of attacks. SDL Threat Modeling Tool 3.1 went live on the Microsoft Download Center on November 6, 2008, carrying the Beta label. The tool has been used extensively within Microsoft,” revealed Steve Lipner, senior director of security engineering strategy in Microsoft’s Trustworthy Computing Group back in September. “This tool allows for structured analysis, tracking and mitigation of potential security and privacy issues, based on a methodology that any software architect can lead effectively. As an integral part of the initiative, Microsoft pointed developers to the SDL Pro Network, the SDL Optimization Model and the Microsoft SDL Threat Modeling Tool 3.0 as resources necessary to increase the security of their software products. Introduction to the Microsoft Security Development Lifecycle (SDL) Secure software made easier. In September 2008, Microsoft announced that it planned to share not only its secure development practices but also the tools it was deploying in order to increase the level of protection for customers with developers industry wide.
Microsoft has made the internal security tool that helped bulletproof the Windows operating system available as a free download.
