Computer risk exposures and security in general are reviewed, and factors suggesting that expert system security is a unique problem are examined. Security requirements associated with the unique characteristics of expert systems are investigated. They include technical aspects of knowledge (certainty factors, symbolic information and special fixes), structure (user interface, knowledge base, inference engine and database), design methodology (prototyping) and the current delivery environment (e.g., PCs and expert system shells). The security of working expert systems as discussed in the literature is examined. Rationales for the current apparent lack of expert system security are analyzed and the impact of possible security controls on expert system users and developers is assessed.<>
