The company said Oracle Internet Directory - a component of Oracle Identity Management, Oracle 9i Database Release 2 and Oracle 9i Label Security Release 2 - had attained Common Criteria Evaluations at EAL4, the highest level generally achieved by commercial software.
Oracle has also completed Common Criteria Evaluations for Oracle 9i Database Release 2 and Oracle 9i Label Security Release 2 on Novell SuSE Linux.
According to Oracle, the evaluation means users can now be confident Linux is built to run mission-critical applications.
It said these were the first evaluations Oracle has completed on the Linux platform that mean users can use independently tested Oracle products with an open source operating system.
Mary Ann Davidson, chief security officer at Oracle, said, "These evaluations underscore our commitment to delivering secure products on Linux."
