Trailrunner7 writes "Despite its reputation for secrecy and technical expertise, the National Security Agency doesn't have a set of secret coding practices or testing methods that magically make their applications and systems bulletproof. In fact, one of the agency's top technical experts said that virtually all of the methods the NSA uses for development and information assurance are publicly known. 'Most of what we do in terms of app development and assurance is in the open literature now. Those things are known publicly now,' Neil Ziring, technical director of the NSA's Information Assurance Directorate, said in his keynote at the OWASP AppSec conference in Washington Wednesday. 'It used to be that we had some methods and practices that weren't well-known, but over time that's changed as industry has focused more on application security.'"
