Three Layer Security Model for Distributed Relational Database

Today we are living in a digital world where we all are connected to an open access network to exchange information. This information is more valuable assets that need protection from unauthenticated access. There are many security models has been proposed to protect the data stored in database but still needs more protection from attacks. In this study we have a three layer security model for relational database. Proposed model builds a security architecture based on access control policy, cryptography techniques and stored procedure. These mechanisms and techniques are combined together to present an interactive three-layer security model for securing relational databases in distributed environment. This model provides a kind of security controlling both in rests of database and data in motion from malicious user and other attacks.
