A Model for When Disclosure Helps Security: What is Different About Computer and Network Security?

This Article asks the question: When does disclosure actually help security? The discussion begins with a paradox. Most experts in computer and network security are familiar with the slogan that there is no security through obscurity. The Open Source and encryption view is that revealing the details of a system will actually tend to improve security, notably due to peer review. In sharp contrast, a famous World War II slogan says loose lips sink ships. Most experts in the military and intelligence areas believe that secrecy is a critical tool for maintaining security. Both cannot be right - disclosure cannot both help and hurt security.
