English Abstract

Database technology are having a major impact on the growing use of computers.

It is fair to say that database will play a critical role in almost all area where computers are used, including business, engineering, medicine, law, education, and library science.

A database contains data of various degree of importance and it is shared among a wide variety of users, so it needs to be protected and managed because any change to the database can affect it and affect other related databases.

Now, many databases are online and they are accessed by multiple users concurrently, so they needs more control and the integrity of the database must be maintained.

In a multilevel secure distributed database management system, users cleared at different security levels access and share a distributed database consisting of data at different sensitivity levels, assigning sensitivity levels, also called security levels, to data is one, which utilizes constraints or classification rules.

Security constraints provide an effective classification policy.

They can be used to assign security levels to the data based on content, and time. This thesis is concerned with the design and implementation of Multilevel Secure (MLS) for Distributed Database Management System (DDBMS).

The proposed system was classified the users according to their roles and the sensitivity of the data that stored in DDB into four levels (Top-secret.

Secret, Confidential, and Unclassified users).

According to their level can be access the database and also provide much protection to data and information that stored in Distributed Database System (DDBMS) by using different security services to authenticate the users, like identification and authentication by using encryption methods to encrypt the data that are transferred between two sites and using Biometrics Authentication (Fingerprints method), to authenticate the administrator of the system. Database security should not only be concerned with the protection of sensitive data, it should also find some mechanisms that allow users to retrieve information in a controlled manner. The proposed system is implemented by using Visual Basic 6.0 to build the relational database, and Matlap to make recognition to the Fingerprints.
