Knowledge Discovery as a Threat to Database Security

This chapter investigates the affect of knowledge discovery from databases on the security of databases. First, it examines the current concern with database systems for security from knowl­ edge discovery. Second, this chapter discusses some of the potential security risks associated with knowledge discovery. Third, some potential structure for the development of controls for such systems is examined. It is suggested that the technology itself and the voluntary or invol­ untary nature of the unauthorized disclosure form a. basis for analysis. Fourth, the quality of database security in general is stressed as an important set of controls to secure against knowl­ edge discovery. Finally, it is noted tha.t any set of controls should be compared with the benefit derived from these controls. Security can be established; however, it is important not to forget that ease (or the decision maker is one of the primary reasons for creating and maintaining the
