Finally, the server object can be invoked by the client application just like a local object. 7 Summary CORBA, an industry specification that has been in development since 1990 by the OMG, allows software objects to talk to each other across the network. It has many advantages. From a business perspective, CORBA can help with legacy integration, which leverages the use of both old and new systems. From a technical point of view, CORBA can provide transparency, platform independence, portability, software reuse, integration, interoperability, flexibility, and scalability.

Somewhat counterintuitively, research in information security has found that it is often also necessary to police write operations to enforce confidentiality. 1 For CORBA security, the following narrow definition of confidentiality is most appropriate: Confidentiality denotes the protection of requests 1. Note that this requires the intent of the privileged user to do so. The Security Basics 41 and replies from unauthorized reading, as well as the restriction of access to target operations that return confidential information, so that only authorized callers can invoke them.

3 Security Properties Within CORBA This section extends our definition of information security by distinguishing a number of different aspects of information security. We first give a generic classification of the main aspects involved and then describe a number of additional requirements for the CORBA security architecture. The discussion will show that there is no single universal terminology that fits all systems. Therefore, we try to identify a set of CORBA specific definitions. Protection of information assets from unauthorized attempts to access information or from interference with its operation is often defined as having the following fundamental goals (as defined in the Common Criteria standard [3]): • Confidentiality: The prevention of unauthorized disclosure of information; 40 Developing Secure Distributed Systems with CORBA • Integrity: The prevention of unauthorized modification of information; • Availability: The prevention of unauthorized withholding of infor- mation or resources.
