Abstract:

Since protection and assurance are the primary concerns in MLS databases, performance has often been sacrificed in some known MLS database approaches. Motivated by performance concerns, a replicated architecture approach which uses a physically distinct backend database management system for each security level is being investigated. This is a report on the behavior and performance issues for the replicated architecture approach. Especially, we compare the performance of the SINTRA1 MLS database system to that of a typical conventional non-secure, single-level database system. After observing the performance bottlenecks for the SINTRA, we present solutions that can alleviate them.
