Most database security models focus on protecting against external unauthorized users. Because multilevel secure databases provide internal security according to user access type, they are a viable option for the security needs of modern database systems. Covering key concepts in database security, this book illustrates the implementation of multilevel security for relational database models. It considers concurrency control in multilevel database security and presents encryption algorithms. It also includes simulation programs and Visual studio and Microsoft SQL Server code for the simulations covered in the text.
Since databases are the primary repositories of information for todays organizations and governments, database security has become critically important. Introducing the concept of multilevel security in relational databases, this book provides a comparative study of the various models that support multilevel security policies in the relational databaseillustrating the strengths and weaknesses of each model.
Multilevel Security for Relational Databases covers multilevel database security concepts along with many other multilevel database security models and techniques. It presents a prototype that readers can implement as a tool for conducting performance evaluations to compare multilevel secure database models.
The book supplies a complete view of an encryption-based multilevel security database model that integrates multilevel security for the relational database with a system that encrypts each record with an encryption key according to its security class level. This model will help you utilize an encryption system as a second security layer over the multilevel security layer for the database, reduce the multilevel database size, and improve the response time of data retrieval from the multilevel database.
Considering instance-based multilevel database security, the book covers relational database access controls and examines concurrency control in multilevel database security systems. It includes database encryption algorithms, simulation programs, and Visual studio and Microsoft SQL Server code.
