Does that mean an individual canвЂ™t threat model alone on a small project? Of course not, but will get the greatest benefit from the activity by including as many project members as possible.

How to perform threat modeling Threat modeling is largely a team activity. LetвЂ™s look at some basic examples of what threat modeling is and what it isnвЂ™t: AВ streamlined approach that melds agile methods and security-the Security DevelopmentВ life-cycle for Agile Development (SDL-Agile) has to be put into practice. Second, the development phases (design, implementation,В verification, and release) associated with the classic waterfall-style SDL do not apply to Agile and must beВ reorganized into a more Agile-friendly format. This means that for each feature, the team does just enough SDL work for thatВ feature before working on the next one. First, SDL additions to AgileВ processes must be lean. However, from an Agile viewpoint, the SDL is heavyweight because itВ was designed primarily to help secure very large products,В Agile practitioners in order to adopt the SDL, two changes must be made. The SDL has been shown to reduce the number of vulnerabilities in shippingВ software by more than 50 percent.

On the other hand, there are serious security issues that the SDL is designed to address, and these issues simply canвЂ™t be ignored for any release-no matter how small.ДЄ set of software development process improvements called the SecurityВ Development life-cycle (SDL) has been developed. With Agile release cycles taking as little as one week, there simply isnвЂ™t enough time for teams to completeВ SDL requirements for every release. But the only way the perception and reality can change is by actively taking steps to integrate security requirements into Agile development methods. There is very little вЂњsecure AgileвЂќ expertise available in the market today. There is a perception today that Agile methods do not create secure code, and, on further analysis, the perception is reality.

In todayвЂ™s highly interconnected world, where there are strong regulatory and privacy requirements to protect private data, security must be treated as a high priority.

Since Agile methods focus on rapidly creating features that satisfy customersвЂ™ direct needs, and security is a customer need, itвЂ™s important that it not be overlooked.

Historically, security has not been given the attention it needs when developing software with Agile methods. Many software development organizations, including product organizations likeВ Microsoft, use Agile software development and management methods to build their applications. PEARL XXII : The key to effectively incorporating threat modeling is to decide on the scope of the threat modeling that will be performed during the various stages of agile development project by incorporatingВ Security DevelopmentВ Life cycleВ for Agile Development projects which includes Threat modelling.
