Abstract :
In this paper we propose a new access control mechanism, Dynamic Sensitivity-Based Access Control (DSBAC), designed to regulate users´ access to sensitive data stored in relational databases. The DSBAC is an extension of the basic mandatory access control (MAC) mechanism, and it uses the M-score (Misuseability score) measure in order to assign, dynamically, an access class to each set of tuples.
