Making databases secure with TRUDATA technology
R.B. Knode, R.A. Hunt · 2003
Trusted database (TRUDATA) technology injects multilevel security (MLS) policy enforcement features and assurances into existing relational database management system (DBMS) products. TRUDATA technology consists of a data model, a security policy model, system architecture, and implementation approach which, together, define a trusted MLS DBMS. The result of applying TRUDATA technology to existing baseline products with suitable characteristics is a trusted DBMS targeted at the B1 and B2 evaluation classes of DOD5200.28-STD as interpreted for DBMSs. By combining a view-based security model and by altering slightly the relational DBMS products without abandoning existing applications investments, the first implementation substantiates the protection and performance capabilities of TRUDATA.>
