PRIVILEGED ACCOUNTS AS A KEY ASPECT OF INFORMATION SECURITY SYSTEMS

Ordering as privileged information

We propose to accelerate the rate of convergence of the pattern recognition task by directly minimizing the variance diameters of certain hypothesis spaces, which are critical quantities in fast-convergence results. We show that the variance diameters can be controlled by dividing hypothesis spaces into metric balls based on a new order metric. This order metric can be minimized as an ordinal r...

Security Aspect of Quantum Key Distribution

Is the newly born quantum cryptography the ultimate solution for information security? A technique needs to be both theoretically strong and practically viable. But quantum cryptography comes to naught in the latter. Unlike many of the classical cryptosystems in use today, whose security often draws on unproven assumptions about the computational complexity of mathematical problems, the securit...

Users as the Biggest Threats to Security of Health Information Systems

There are a lot of researches in the world about attacks on information systems (IS). Although there have been many attempts to classify threats of IS’s especially in Health Information Systems (HIS), it is still necessary for all health organization to identify new threats and their sources which threaten security of health care domain. The main aim of this paper is to present a research agend...

Information Systems Security Outsourcing Key Issues: a Service Providers' Perspective

There is a perception that information systems security outsourcing, in spite entailing a relationship between a client and one or more providers, tends to be studied and analysed from the perspective of the client. A gap is then believed to exist in the study of the information systems security outsourcing relationship from the point of view of the service provider. This research aims to ident...
