Informative Signal Analysis: Metrology of the Underwater Geomagnetic Singularities in Low-Density Ionic Solution (Sea Water)

引用

Journal of Signal and Information Processing 2018年第1期9卷 1-23页

作者： Osvaldo Faggioni Maurizio Soldani Giacomo Cozzani rodolfo zunino DITEN-SEALab-ACM Laboratory Department of Electric Electronic Telecommunication Engineering and Naval Architecture University of Genoa Genoa Italy Istituto Nazionale di Geofisica e Vulcanologia Rome Italy CNR—Consiglio Nazionale delle Ricerche ITD—Istituto per le Tecnologie Didattiche Genoa Italy

The paper tackles the problem of reading singularities of the geomagnetic field in noisy underwater (UW) environments. In particular, we propose a novel metrological approach to measuring low-amplitude geomagnetic signals in hard noisy magnetic environments. This research action was launched to develop a detection system for enforcing the peripheral security of military bases (harbors/coasts and landbases) and for asymmetric warfare. The concept underlying this theory is the spatial stability in the temporal variations of the geomagnetic field in the observation area. The paper presents the development and deployment of a self-informed measurement system, in which the signal acquired from each sensor—observation node—is compared with the signal acquired by the adjacent ones. The effectiveness of this procedure relates to the inter-node (sensor-to-sensor) distance, L;this quantity should, on one hand, correlate the noise and, on the other hand, decorrelate the target signal. The paper presents the results obtained, that demonstrate the ability of self-informed systems to read weak magnetic signals even in the presence of very high noise in low-density ionic solutions (i.e. sea water).

The Guidelines to Adopt an Applicable SIEM Solution

Journal of Information Security 2020年第1期11卷 46-70页

The need for SIEM (Security Information and even Management) systems increased in the last years. Many companies seek to reinforce their security capabilities to better safeguard against cybersecurity threats, so they adopt multi-layered security strategies that include using a SIEM solution. However, implementing a SIEM solution is not just an installation phase that fits any scenario within any organization;the best SIEM system for an organization may not be suitable at all for another one. An organization should consider other factors along with the technical side when evaluating a SIEM solution. This paper proposes an approach to aid enterprises, in selecting an applicable SIEM. It starts by suggesting the requirements that should be addressed in a SIEM using a systematic way, and then proposes a methodology for evaluating SIEM solutions that measures the compliance and applicability of any SIEM solution. This approach aims to support companies that are seeking to adopt SIEM systems into their environments, suggesting suitable answers to preferred requirements that are believed to be valuable prerequisites an SIEM system should have;and to suggest criteria to judge SIEM systems using an evaluation process composed of quantitative and qualitative methods. This approach, unlike others, is customer driven which means that customer needs are taken into account when following the whole approach, specifically when defining the requirements and then evaluating the suppliers’ solutions.
