The aim of this internship was to provide to Amadeus security team some monitoring tools dedicated to a specific family of products and services, called SAS. The project, named FUM (Functional Monitoring), consisted in events modelling, development of several web dashboards and activation of an email notification system. Everything has been realized using the Splunk software engine and, in parallel, well-documented on Confluence (the internal Amadeus wiki repository). Finally, governance has been defined to provide the rules and the best practices for all the developers that, in the future, may need to modify the source code or to develop new tools.
