Oracle updates secure database with replication features

The latest release of Oracle?s secure database server, Trusted Oracle7, is geared to improve security in distributed database environments. It is the only multi-level secure database server on the market to support advanced replication.

In addition, release 7.2 provides new options for customers to automate and enforce their security policies within their organisations.

The advanced replication capabilities automatically maintain copies of data at different sites in the organisation, so that information remains consistent when updated at different locations. Data is distributed while enforcing multi-level security by using labelled data management.

Trusted stored procedures are another addition. Security administrators can grant mandatory access privileges to procedures, allowing them to access specified levels of data, without giving these privileges directly to users. This is in line with Oracle?s principle of giving users only those authorisations that are essential to their job.

With release 7.2 come versions of Developer/2000, Secure Network Services and Oracle Webserver, optimised for the Trusted product. Developer/2000 is a rapid development environment for scalable applications; SNS provides authentication services and encryption for SQL*Net traffic; and Webserver enables Web clients to invoke Trusted Oracle7 procedures to dynamically generate Web documents.

The new version of the secure database is available immediately on Digital MLS+ and Data General DG/UX with DSO, both secure operating systems. In the next quarter, the product will ship for the secure versions of Hewlett-Packard and Sun Unix, with other platforms to follow next year.
