DREs have lagged in support of security. To address this deficiency, this paper concentrates on proposing a technique for seamlessly integrating a role-based security model, authorization, authentication, and enforcement into a DRE, including our prototyping with the JINI DRE.

In this chapter, we focus on assurance for the timeframe

In previous work, the authors developed a set of techniques for defining and analyzing URBS for an application. They extend this work by considering an actual individual's authorized access rights in an application,

ADAM/DDD is a design tool that promotes the specification of a complete and accurate scenario for a given experiment. From conceptually structured designs, ADAM/DDD generates the information and facts that

Architectural specifications need to define the key aspects of the application, including its intended functions, interfaces, interoperability requirements, distributability, scalability, extensibility, target platforms and networks, and required middleware services. In this paper, we present an architectural extension for specifying distributable components of the application and for quantifying their interaction patterns. The goal of the specification is to serve as the basis for obtaining optimal distributions of the application components over a target network that minimizes remote communication among the components. The optimal distributions are obtained by using the architectural specification to derive a BIP (binary integer programming) model and solving the resulting system. We formalize the object-oriented architectural style using the Z specification language. This style defines the detailed information necessary to derive optimal distributions using the BIP model.

Java is targeted for applications that include: advanced capabilities in WWW browsers via applets; enterprise computing with database connectivity, CORBA, and RMI; usage in personal, commercial, and consumer market products; embedded computing applications with real-time constraints; and, smart card technology. Security is an integral component of many of these applications, to control access and prevent misuse. The purpose of this chapter is to focus on the security capabilities and potentials of Java. There must be an understanding of the available security primitives in Java, an investigation of the ability of Java to support existing object-oriented security approaches, and a consideration of potential security solutions for distributed object computing applications. 1.1 INTRODUCTION T...
