Abstract
Software tools assist an access-policy analyst or creator to debug and/or author access policies. An access request contains a query that evaluates to either true or false depending on whether access is to be allowed. Abduction may be used to generate assumptions that, if true, would cause the access request to be true. The tool may perform analysis on the generated assumptions, such as: comparing the assumptions with tokens to detect errors in the tokens or to suggest changes to the tokens that would cause the query to be satisfied, or comparing the assumptions to a meta-policy. The tool may allow an analysis, policy author, or other person to interactively walk through assumptions in order to see the implications of the access policy.
