Abstract:

Most of the commercial DBMS products are lower in the security class ratings. Considering facts, a scheme to strengthen the security of database by a security enhanced system is proposed. The design of security enhanced system is specified on the base of discussing the security aspects of database and this system is also taken to an anti-attack analysis. This system ensures the security of database server by certificating authority and tuple-level mandatory access control on the basis of network isolation. Using this system to strengthen the security of database is practical and feasible.

Key words: oracle, network isolation, certification authority, mandatory access control
