Introduction to Sentinel KQL Developer

Sentinel KQL Developer is a specialized tool designed to aid users in crafting and optimizing Kusto Query Language (KQL) queries specifically for Microsoft Sentinel. Its core purpose is to streamline the process of creating complex queries that can analyze and extract insights from vast amounts of security data collected by Microsoft Sentinel. By leveraging the extensive knowledge of Sentinel's data schema and the intricacies of KQL, Sentinel KQL Developer enables users to formulate precise queries to detect threats, investigate incidents, and perform advanced security analytics. An example scenario illustrating its use is in threat hunting, where a security analyst needs to query across multiple data tables (e.g., log files, sign-in records, and incident reports) to identify unusual activity or pinpoint the source of a security breach.

Main Functions of Sentinel KQL Developer

  • Query Crafting Assistance

    Example Example

    Providing syntax guidance and table schema verification to create a query that identifies failed sign-in attempts from unusual locations.

    Example Scenario

    A security analyst is investigating potential breaches and needs to find sign-in attempts that failed due to impossible travel scenarios. Sentinel KQL Developer assists in creating a query that cross-references geographical locations from sign-in logs against known user profiles.

  • Schema Validation

    Example Example

    Verifying the correct field names and data types when creating a query to ensure it runs without errors.

    Example Scenario

    An IT administrator wants to generate a report on user activities within a specific application. They use Sentinel KQL Developer to ensure the query utilizes the correct field names from the 'OfficeActivity' table, such as 'Site_Url' instead of 'SiteUrl', and 'UserId' instead of 'UserPrincipalName'.

  • Custom Query Suggestions

    Example Example

    Suggesting optimized queries for specific use cases, like detecting anomalous behavior or auditing security policies.

    Example Scenario

    A compliance officer needs to audit security policy changes over the last quarter. Sentinel KQL Developer suggests a query that extracts this information from the 'AuditLogs' and 'SecurityEvent' tables, efficiently summarizing the data to highlight any deviations from the norm.
