Abstract :
Since protection and assurance are the primary concerns in multilevel secure (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 back-end 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 SINTRA (Secure INformation Through Replicated Architecture) MLS database system to that of a typical conventional (non-secure, single-level) database system. After observing the performance bottlenecks for SINTRA, we present solutions that can alleviate them
