On the systemic enterprise architecture methodology (seam)

Abstract: This paper presents an original methodology for Enterprise Architecture. Enterprise Architecture is the discipline whose purpose is to align more effectively the strategies of enterprises together with their processes and their resources (business and IT). Enterprise architecture is complex because it involves different types of practitioners with different goals and practices. Enterprise Architecture can be seen as an art; it is largely based on experience but does not have strong theoretical foundations. As a consequence, it is difficult to teach, to apply, and to support with computer-aided tools. This paper presents how system sciences, by defining the concept of the systemic paradigm, can provide these necessary theoretical foundations. Thanks to our systemic paradigm, the enterprise architects can improve their understanding of the existing methodologies and thus find explanations for the practical problems they encounter. This paper then gives a concrete example of the application of the systemic paradigm: the Systemic Enterprise Architecture Methodology (SEAM) - an original methodology. With SEAM, architects can use a methodology that alleviates most of their practical problems and that can be supported by a tool.

N-grams-based file signatures for malware detection

Abstract: Malware is any malicious code that has the potential to harm any computer or network The amount of malware is increasing faster every year and poses a serious security threat Thus, malware detection is a critical topic in computer security Currently, signature-based detection is the most extended method for detecting malware Although this method is still used on most popular commercial computer antivirus software, it can only achieve detection once the virus has already caused damage and it is registered Therefore, it fails to detect new malware Applying a methodology proven successful in similar problem-domains, we propose the use of ngrams (every substring of a larger string, of a fixed lenght n) as file signatures in order to detect unknown malware whilst keeping low false positive ratio We show that n-grams signatures provide an effective way to detect unknown malware

Business Model Analysis Applied To Mobile Business

Abstract: Mobile business is a young promising industry created by the emergence of wireless data networks.. Similar to other emerging industries, it is characterized by a large number of uncertainties at different levels concerning technology, demand and strategy. This paper focuses on the strategic uncertainties, where a large number of actors are trying a number of strategic approaches to position themselves in the most favourable position in the value system. As a consequence, they are experimenting with a number of innovating business models. We argue that successful business models are likely to be the ones that best address the economic peculiarities underlying this industry, like mobility, network effects and natural monopolies. The paper presents the principal classes of actors that will participate in the mobile business industry and give an overview of their business models based on a formalized ontology.

Service Engineering for the Internet of Services

Abstract: The Internet and the Web have extended traditional business networks by allowing a Web of different digital resources to work together to create value for organizations. The most industrialized countries have entered a post-industrial era where their prosperity is largely created through a service economy. There is a clear transition from a manufacturing based economy to a service based economy. From the technological perspective, the development of Web-based infrastructures to support and deliver services in this new economy raises a number of challenges. From a business perspective, there is the need to understand how value is created through services. In this paper, we describe how we propose to address these two perspectives and realize the vision of the Internet of Services (IoS), where Web-based IT-supported service ecosystems form the base of service business value networks. This paper addresses the main challenging issues that need to be explored to provide an integrated technical and business infrastructure for the Internet of Service.

SCHEMA EVOLUTION IN WIKIPEDIA - Toward a Web Information System Benchmark

Abstract: Evolving the database that is at the core of an Information System represents a difficult maintenance problem that has only been studied in the framework of traditional information systems. However, the problem is likely to be even more severe in web information systems, where open-source software is often developed through the contributions and collaboration of many groups and individuals. Therefore, in this paper, we present an indepth analysis of the evolution history of the Wikipedia database and its schema; Wikipedia is the best-known example of a large family of web information systems built using the open-source software MediaWiki. Our study is based on: (i) a set of Schema Modification Operators that provide a simple conceptual representation for complex schema changes, and (ii) simple software tools to automate the analysis. This framework allowed us to dissect and analyze the 4.5 years of Wikipedia history, which was short in time, but intense in terms of growth and evolution. Beyond confirming the initial hunch about the severity of the problem, our analysis suggests the need for developing better methods and tools to support graceful schema evolution. Therefore, we briefly discuss documentation and automation support systems for database evolution, and suggest that the Wikipedia case study can provide the kernel of a benchmark for testing and improving such systems.
