The Computer Security Foundations Symposium is an annual conference for researchers in computer security, to examine current theories of security, the formal models that provide a context for those theories, and techniques for verifying security. It was created in 1988 as a workshop of the IEEE Computer Society Technical Committee on Security and Privacy, in response to a 1986 essay by Don Good entitled "The Foundations of Computer Security - We Need Some." The meeting became a "symposium" in 2007, along with a policy for open, increased attendance.
