Abstract

Existing SQL Access Control Mechanisms are extremely limited. Attackers can access the sensitive information through escalating their privileges. Practical attacks against existing database are increasing nowadays by using database features such as triggers and integrity constraints. Moreover the theories behind access control mechanism lack adequate security policies and attackers capabilities. This paper addresses the three main privilege escalation attacks by using database features and its prevention methods.

Keywords: DBMS, DB security, Access control mechanism, Insider attacks, Privilege escalation, SQL.
