ISSA National Capital Chapter August meeting topic:

Enumerating software security design flaws throughout the SSDLC
by John Willis


 The security challenges we face today are numerous. Yet, we just can’t seem to produce software without including countless security vulnerabilities. About one-third (1/3rd) of all software security vulnerabilities are due to design errors. To further compound the problem, nonfunctional security requirements often do not get translated to real technical security design features, or controls. To make matters worse, security design features have their own dependencies. Bundle this with design errors that may or may not be uncovered through threat modeling, and it is no surprise that we have the perfect storm. Worse yet, any security functionality implemented to address nonfunctional requirements is unlikely to receive attention during testing. Unfortunately, if we don’t address these security design flaws the testers may never notice anyway!

A methodology and evolving mock-up/prototype is introduced to address these problems. A graphical tool that is SysML compatible is the ultimate goal. The hypothesis is that by employing the above methodology/tool we should be able to establish order where there is currently chaos regarding the identification and satisfaction of security requirements, not only in the solution space—but throughout the SSDLC as well.
