Testing for security during development: why we should scrap penetrate-and-patch

In the commercial sector security analysis has traditionally been applied at the network system level, after release, using tiger team approaches. After a successful tiger team penetration, specific system vulnerability is patched. I make a case for applying software engineering analysis techniques that have proven successful in the software safety arena to security-critical software code. This work is based on the generally held belief that a large proportion of security violations result from errors introduced during software development.
