Description

Threat modeling is a great method to identify potential security weaknesses and enables architects and developers to efficiently prioritize their security investment, thus mitigating and preventing those vulnerabilities that would most likely cause the most damage. Unfortunately, though threat modeling provides a far greater return than most any other security technique in a development process, it’s apparently “common knowledge” that threat modeling is supposed to be heavily resource intensive, requires a full team of expensive security professionals, takes up far too much developer time, and doesn’t scale at all.

The common knowledge is wrong. In fact, using a lightweight, value-driven approach, skilled development teams can very efficiently ensure that the features they build can protect themselves, the application, and the business value that the features are intended to generate. Value-driven threat modeling offers an alternative to top-heavy, big-model-up-front threat modeling in favor of agility, speed, and integration with the existing development cycle to not just to minimize risk but to lower security costs.

Avi Douglen walks you through value-driven threat modeling with a quick overview of its purpose and the benefits of using it early in the development process and shows you how to incorporate it into your existing agile methodologies. Avi outlines some of the drawbacks and constraints of these approaches, especially from the perspective of the development team to explore how this clashes with the typical workflow. You’ll learn how developers can efficiently threat model their application by integrating it into standard workflows to improve development. Avi runs through a threat modeling process for a sample feature and highlights the differences from classic threat modeling. And of course, you’ll see how security can participate productively in the agile development process, leveraging developers’ own habits to their benefit. He provides several techniques or shortcuts to facilitate adoption by R&D as well as constraints and limitations.

Prerequisite knowledge

  • Familiarity with modern development practices and agile methodology
  • A basic understanding security concepts (useful but not required)

What you'll learn

  • Learn what threat modeling is and why you need it
  • Discover how to build a threat model for an application
  • Identify a strategy to integrate a threat modeling process in you own agile development workflow
