ARIMA Based Network Anomaly Detection

Abstract: An early warning system on potential attacks from networks will enable network administrators or even automated network management software to take preventive measures. This is needed as we move towards maximizing the utilization of the network with new paradigms such as Web Services and Software As A Service. This paper introduces a novel approach through using Auto-Regressive Integrated Moving Average (ARIMA) technique to detect potential attacks that may occur in the network. The solution is able to provide feedback through its predictive capabilities and hence provide an early warning system. With the affirmative results, this technique can serve beyond the detection of Denial of Service (DoS) and with sufficient development; an automated defensive solution can be achieved.

Introducing Windows Azure

Abstract: Windows Azure is Microsoft's next-generation cloud-computing operating system and is designed to provide companies with new business opportunities as they migrate toward hosted services. Introducing Microsoft Azure provides all the information developers need to get started with this new technology and apply it across a range of situations. Presented in a clear, concise manner, this book provides a carefully measured learning curve for surmounting the architectural and coding challenges that need to be faced when building a well-balanced Windows Azure service. What you'll learn Understand the critical concepts of Azure, such as data storage and retrieval, .NET Services, and SQL Azure Learn to write Azure code and architect cloud-based solutions Gain a comprehensive understanding of cloud computing and how the hosted architecture will impact the way organizations host, deploy, and maintain their solutions Integrate .NET Services and SQL Azure into existing applications to increase their functionality Understand how Azure can be leveraged to solve a variety of programming tasks through extensive exercises and recipes Who is this book for? Introducing Windows Azure is for .NET architects and developers who want to learn how to provide business solutions based on the Microsoft Azure Services platform. Software as a Service (SaaS), a major trend in the computing industry, will grow exponentially in the coming years. This is a book that every developer should have on their bookshelf.

Defining Composite Configurable SaaS Application Packages Using SCA, Variability Descriptors and Multi-tenancy Patterns

Abstract: Currently, several vendors and projects are building proprietary SaaS platforms where more and more applications are hosted in a Software as a Service business model. However, these proprietary platforms prevent that applications offered by different SaaS application vendors can be easily reused on the platforms offered by the different SaaS hosting providers. In this paper we describe a package format for composite configurable SaaS application packages for applications developed following a service oriented architecture. We show how the service component architecture (SCA) can be extended with variability descriptors and SaaS multi-tenancy patterns to package and deploy multi- tenant aware configurable composite SaaS applications.
