This is an extract of a real assignment I worked on for a leading italian bank. In greater detail, the audit team of the bank asked me to analyze computer-generated records in order to identifiy unauthorized accesses to sensitive data by employees of a specific company department. To achieve this goals, I build a model to identify suspicious logs and then I built a smart dashboard aimed at showing results and allowing audit team to proper monitor the phenomenon.
Data were provided by IT department regarding all system accessess related to the specific department in scope happened between 2019 and 2020. Input data have been completely anonymized since I deal with very sensitive information.
Several suspicious behaviours were identified by the analysis, providing a baseline for audit team for further investigation.
