Information security governance in big data environments: A systematic mapping

Information security governance is an important aspects for all organizations. Given the crucial importance of IT systems and the increasing range of threats these systems are facing, there is an increasing interest on the topic. On the other hand, Big Data environments are also beginning to be more pervasive as IT is increasing its importance for organizations worldwide. In order to better know which aspects are the most important for the intersection of Big Data and information security governance, authors present in this paper a systematic mapping on this topic. Authors illustrate challenges and gaps concerning the topic and clarify these challenges by means of a classification of the environments they take place, the security risk spectrums they concern, and the security governance measures they take to mitigate them; by providing solutions as in a framework, model, software or tool, wherever possible. Results are expected to be useful for IT security professionals and information systems practitioners as a whole.publishedVersio

Efficiently Managing the Security and Costs of Big Data Storage using Visual Analytics

We are currently living in the age of big data with ever growing volumes of heterogeneous and fast moving data. Whether they are mobile devices, internal or external systems or cloud-based systems data is generated, stored, processed and distributed in many different systems. This leads to various information security and privacy risks. To address these issues, especially from the viewpoint of data management and data governance we propose a conceptual analysis model. Thereby, our model takes into account the dimension of data storage location together with their respective risks and costs while considering the strategic value and sensitivity of data assets. For demonstrating our approach we developed a visual analytics web application which is based on parallel sets visualizations. By being able to interactively explore the analysis dimensions users are supported in developing enhanced situational awareness for making decisions in the context of secure and economical data storage
