  1. Dan Simon is wrong July 8, 1998

  2. “What is Security?” • “Security is about implementing people’s preferences for privacy, trust and information sharing (i.e., their `Security Policies’)” • Wrong (or incomplete) • Security is also about eliminating unforeseen consequences • Constructing the policy is the hard part

  3. You can’t handle the truth • Who should be able to open the front door on my house? • Me, my family, our guests • Police, firefighters, paramedics • But they should be logged and audited • Locksmiths? • It’s hard to construct the right lists • Physical metaphors may not help

  4. Social constructs • Security policies are based on experience • Less experience on computers than in real world • Unforeseen consequences may be far more numerous • Predicting consequences is computationally complex • Analogies may not maintain consequences

  5. Desiderata • I need an administrator • I’m not alone • My policy might simply parameterize the administrator’s policy • I need auditing • I need undo • I need someone to explain my policy to me
