Outils statistiques pour la fouille de fichiers de logs
Yves Agostini · HAL (Le Centre pour la Communication Scientifique Directe) · 2015
After a quick reminder of basic statistics and an introduction to the open source software R, this presentation will address data searching from different types of trace files using statistical methods.The goals are to search for abnormal events with the aim of preventing them, and searching for compromising indicators.We will see that the statistical approach is by nature inevitably imprecise, and there is no absolute methodology in data searching. Nevertheless, the results obtained allow the implementation of additional detection procedures on top of simple event counting.
