OrbixSecurity, now shipping for Unix and Windows NT servers, is based on the Object Management Group's CORBA (common object request broker architecture) Level 1 security specification. That specification, in turn, is based on a security technology, called Kerberos, intended to work with software from multiple companies.
OrbixSecurity provides services such as authentication of users, authorization to allow access to system services, message protection through encryption support, and system logging to track any security violations.
The tool works with Orbix object request broker middleware, which is used to glue component applications and database software together into working business systems.
CORBA is a widely adopted standard that defines communications between applications and components. The OMG, the body charged with promoting the standard, describes CORBA as a way to allow applications to communicate with one another no matter where they are located or who has designed them.
COM, backed by Microsoft, is a similar technology, but tilted toward Microsoft's own technologies, such as Windows NT--although the company does support COM on other makers' operating systems.
Iona has also licensed COM from Microsoft and recently added COM support to its Orbix product line.
