Behavioral Security Modeling: Functional Security Requirements

In my Behavioral Security Modeling talk at OWASP AppSec USA 2011, I promised a white paper on BSM. Since then, I enlisted the aid of Karl Brophey, a friend who has a wealth of experience in software development and architecture, and the result of our collaboration is finally complete! I’m pleased to formally announce the release of the first BSM white paper, “Behavioral Security Modeling: Functional Security Requirements.” Karl and I will be speaking about the paper today at Secure360 in St Paul. Hope to see you there!

Abstract:

Defining functional security requirements is a key component of Behavioral Security Modeling, a method to improve security through accurately modeling human/information interactions in social terms. The paper proposes a practical, SDLC agnostic method for gathering functional security requirements by establishing limits on interactions through a series of questions to identify, clarify, and uncover hidden constraints. Five categories of constraints are presented, along with advice and “requirement patterns” to facilitate discussions with stakeholders and translate business needs into unambiguous security requirements. General advice on improving constraints, implementation considerations, security actions, quality assurance, and documenting post conditions are also discussed.

Version 1.0 disclaimer: this white paper attempts to formally capture our collective knowledge on how to effectively define functional security requirements. The next step is to test the theory by implementing the approach in a number of application development environments.
