INTELLIGENT USE OF USER DATA TO PRE-EMPTIVELY PREVENT EXECUTION OF A QUERY VIOLATING ACCESS CONTROLS

A system, method and article of manufacture are provided for securing data. Security rules are defined for fields and/or field values. The security rules specify one or more users to which the rules apply. A query is examined for content and a determination is made as to whether security action is required based on the content (e.g., a field and/or a value of the field) and user-specific data.
