Database security

A computer program product comprising one or more computer readable storage media having program instructions collectively stored on the one or more computer readable storage media, the program instructions executable to:

• obtain security policies associated with a database hosted by a database server;
• obtain first database data associated with the database;
• create a knowledge distillation model using the security policies and the first database data using a feed forward network to train a neural network;
• obtain second database data associated with the database;
• create a classification model using the second database data and an output of the knowledge distillation model using logistic regression;
• receive a client database request to the database;
• determine a new security policy rule set using the classification model;
• and
• apply the new security policy rule set to the client database request.

A system comprising:

• a processor, a computer readable memory, one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable to:
• obtain security policies associated with a database hosted by a database server;
• obtain first database data associated with the database;
• create a knowledge distillation model using the security policies and the first database data using a feed forward network to train a neural network;
• obtain second database data associated with the database;
• create a classification model using the second database data and an output of the knowledge distillation model using logistic regression;
• receive a client database request to the database;
• determine a new security policy rule set using the classification model;
• and
• apply the new security policy rule set to the client database request.
