Proposal Abstract: With the arrival of a commercially available implementation of Security Level 2 of the CORBA Security Service (i.e., Adiron's ORBASec SL2), it is now possible to begin exploring some of the issues associated with actually using the CORBAsec interfaces in the design and implementation of a security-aware CORBA application. As part of its DOCSec Experience Laboratory task, NSA will develop a security-aware interactive application on the ORBASec SL2 product. The application will essentially be a bulletin board system with an integrated notion of user/administrator identity and role and a security policy for controlling access to parts of the bulletin board based on these attributes. If time permits, a sensitivity attribute (e.g., clearance) may also be added. This presentation will describe the development team's experiences in designing, implementing and operating the application. It is hoped that these experiences will be helpful to other organizations attempting to use CORBAsec as a component of their software architecture. We also hope to have the application available as one of the demonstration displays. Primary POC: Dave Chizmadia; dmc@tycho.ncsc.mil Backup POCs: Darrel Sell; dgs@tycho.ncsc.mil Capt.
