The technology evaluation of database management system has integrated with significant improvement in distributed computing. The requirements for multilevel security have been shown to conflict with database integrity and consistency. Concurrency control ensures that individual users meet consistent states of the databases with security. Concurrency control is an integral part of the database systems to manage the concurrent execution of operations by different transactions in the same data or distributed data with consistency. In this paper, it is proposed a model to enhance the performance of concurrent transactions for multilevel security for distributed database. This model reduces the data access time and wait time for every transaction monitored by the sub-query analyzer. The simulation study reveals the effective enhancement of performance for concurrent transactions with different levels of security.
