A Transaction-Based Purpose-Oriented Access Control Model for Information Flow Management
نویسندگان
چکیده
Distributed applications are realized by cooperation of multiple objects. Each object is manipulated through a method supported by the object and then the method may further invoke methods of other objects. Purpose-oriented access rules indicate what methods in objects can invoke methods of other objects. Information flow among the objects occurs if the requests and responses of the methods carry data. The information flow depends on an invocation sequence of methods. We discuss how the invocation sequence of methods influences the information flow.

متن کاملA hybrid approach for database intrusion detection at transaction and inter-transaction levels
Nowadays, information plays an important role in organizations. Sensitive information is often stored in databases. Traditional mechanisms such as encryption, access control, and authentication cannot provide a high level of confidence. Therefore, the existence of Intrusion Detection Systems in databases is necessary. In this paper, we propose an intrusion detection system for detecting attacks...
متن کاملA Purpose-Oriented Access Control Model for Object-Based Systems
Distributed applications are modeled in an object-based model like CORBA [1]. Here, the system is a collection of objects. The objects are manipulated only through operations supported by themselves. The purpose-oriented model [2] is proposed where an access rule shows for what each subject s manipulates an object o by an operation t of o so as to keep the information flow legal. The purpose of...

متن کاملA Purpose-Oriented Access Control Model
In distributed applications, multiple objects cooperate to achieve some objectives. Each object is manipulated through an operation supported by the object and then the operation may further invoke operations of other objects, i.e. nested operations. Purpose-oriented access rules indicate what operation in each object can invoke operations of other objects. Information flow among the objects oc...
