Abstract
Distributed systems are at risk of variety of Security attacks. During this paper we glance at the protection problems of object-based distributed systems, and propose a model supported labeling for construction security. The purpose of this model is to preserve the data Flow security during a distributed object-oriented system. and additionally the protection threats to such systems. we have a tendency to postulate various modeling prospects, and manufacture a particular Set of security properties that describe a construction Secure object model. This explicit model mustn't be thought of as a remedy, however rather ought to demonstrate hon. the assorted modeling choices ar mirrored in Associate in Nursing actual model. we have a tendency to conclude with a discussion of possible avenues of future analysis.
