A risk inventory provides an integrated view on risk management artifacts, e.g., risks, risk controls, and performance indicators. In this paper, we show how adapting the enterprise architecture management processes (EAM) may provide a foundation for an integrated IT risk inventory. Based on a design research approach, we develop a systematic approach for integrating the disciplines of risk man...

In this paper we propose a novel approach for the systematic assessment and analysis of IT related risks in organisations and projects. The approach is model-driven using an enterprise architecture as the basis for the security management process. Using an enterprise architecture it is possible to provide an integrated description of an organisation’s structure, processes and its underlying IT ...

IT risk management is an important challenge for businesses and software vulnerabilities are a major source of IT risks, as the 2006 CSI/FBI Computer Crime and Security Survey [GLLR06] demonstrates. According to the survey, many companies consider it important to quantify the losses attacks against their IT systems cause but are unable to do so. In service-oriented architectures, we see a promi...

The use of Information Technology (IT) in organizations is subject to various kinds of potential risks. Risk management is a key component of project management enables an organization to accomplish its mission(s). However, IT projects have often been found to be complex and risky to implement in organizations. The organizational relevance and risk of IT projects make it important for organizat...

A new combinatorial characterization of a gray-tone image called Euler Vector is proposed. Euler number of a binary image is a well-known topological feature, which remains invariant under translation, rotation, scaling, and rubber-sheet transformation of the image. Euler vector comprises of a 4-tuple, where each element is an integer representing the Euler number of the partial binary image fo...

Median filters and rank-order filters are generally considered to be more time consuming than, e.g., averaging filters. With the new algorithm presented in this report the opposite turns out to be true. The median (or any other rank-order value) is obtained by examining the bits of the arguments columnwise starting with the most significant bits. Hardware implementations suitable for parallel p...

Background Brazil is a country of Portuguese colonization with massive numbers of immigrants and Portuguese descendants (25 millions). At least half of all Brazilian Y chromosomes are from Portuguese origin. Nevertheless, this population suffered miscegenation with native Indians and African descendants. African descendants Brazilians have 48% of non-African genes, probably from Portuguese asce...
