A security policy analyzer service of a computing resource service provider performs evaluations of security policies provided by the service provider's users, to determine whether the security policies are valid, satisfiable, accurate, and/or sufficiently secure. The service may compare the user-provided policy to a stored or best-practices policy to begin the evaluation, translating encoded security permissions into propositional logic formulae that can be compared to determine which policy is more permissive. The service determines values of the parameters in a request for access to a computing resource based on the policy comparison, and generates request contexts using the values. The service uses the request contexts to generate one or more comparative policies that are then used iteratively as the second policy in the comparison to the user-provided policy, in order to produce additional request contexts that represent allow/deny “edge cases” along the borders of policy permission statements.
