The replicated architecture for multilevel secure database systems provides security by replicating data into separate untrusted single-level database systems. To be successful, a system using the replicated architecture must have a concurrency and replica control algorithm that does not introduce any covert channels. Jajodia and Kogan have developed one such algorithm that uses update projections and a write-all replica control algorithm. Here we describe an alternative algorithm. The new algorithm uses replicated transactions and a set of queues organized according to security class. A new definition of correctness is required for this approach, so we present one and use it to show that our algorithm is correct. The existence of this new algorithm increases the viability of the replicated architecture as an alternative to kernelized approaches.

Replicated architecture has been proposed as a way to obtain acceptable performance in a multilevel secure database system. This architecture contains a separate database for each security level such that each contains replicated data from lower security classes. The consistency of the values of replicated data items must be maintained without unnecessarily interfering with concurrency of database operations. This paper provides a protocol to do this that is secure, since it is free of covert channels, and also ensures one-copy serializability of executing transactions. The protocol can be implemented with untrusted processes for both concurrency and recovery.

Multilevel Secure Transaction Processing available in PDF, EPUB and Kindle. Information security is receiving a great deal of attention as computers increasingly process more and more sensitive information. A multilevel secure database management system (MLS DBMS) is designed to store, retrieve and process information in compliance with certain mandatory security requirements, essential for protecting sensitive information from unauthorized access, modification and abuse. Such systems are characterized by data objects labeled at different security levels and accessed by users cleared to those levels. Unless transaction processing modules for these systems are designed carefully, they can be exploited to leak sensitive information to unauthorized users. In recent years, considerable research has been devoted to the area of multilevel secure transactions that has impacted the design and development of trusted MLS DBMS products. Multilevel Secure Transaction Processing presents the progress and achievements made in this area. The book covers state-of-the-art research in developing secure transaction processing for popular MLS DBMS architectures, such as kernelized, replicated, and distributed architectures, and advanced transaction models such as workflows, long duration and nested models. Further, it explores the technical challenges that require future attention. Multilevel Secure Transaction Processing is an excellent reference for researchers and developers in the area of multilevel secure database systems and may be used in advanced level courses in database security, information security, advanced database systems, and transaction processing.
