Secure Databases: Constraints, Inference Channels, and Monitoring Disclosures

  title={Secure Databases: Constraints, Inference Channels, and Monitoring Disclosures},
  author={Alexander Brodsky and Csilla Farkas and Sushil Jajodia},
  journal={IEEE Trans. Knowl. Data Eng.},
ÐThis paper investigates the problem of inference channels that occur when database constraints are combined with nonsensitive data to obtain sensitive information. We present an integrated security mechanism, called the Disclosure Monitor, which guarantees data confidentiality by extending the standard mandatory access control mechanism with a Disclosure Inference Engine. The Disclosure Inference Engine generates all the information that can be disclosed to a user based on the user's past and… CONTINUE READING
