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. The atmosphere of the symposium is informal, often in a peaceful, rural setting that encourages an exchange of thoughtful technical discussion by all attendees, both during and after scheduled presentations. It was held for seven years at the Franconia Inn, Franconia, New Hampshire, USA (pictured above), and subsequently at various European and North American locations.
