Azure Sentinel is a\ncloud based SIEM system. In this research we try investigating usage of Azure Sentinel and\nusing its own analytics queries and, we made our own custom queries for the purpose. Analyzation queries are made for user account-based security threat scenarios.\nIn this research we created a REST service which was used for simulating user accountbased security threats. Research is done based on REST service logs and Azure Active Directory authentication logs.\nIn this research we get new information about using Azure Sentinel, whether can you make\nyour own analytics queries for it and also we get if there is a good reason to use application\nlogs for analytics. As a result, we can assume it is good to use Azure Sentinal analytics for\nuser account-based threat detection. It can be used with custom or ready-made analytic queries for analyzation.
