Requirements
Planned changes

- Ensure that multiple alerts generated by rulequery1 in response to a single user launching Azure Cloud Shell multiple times are consolidated as a single incident.
- Implement the Windows Security Events via AMA connector for Microsoft Sentinel and configure it to monitor the Security event log of Server1.
- Ensure that incidents generated by rulequery1 are closed automatically if Azure Cloud Shell is launched by the company's SecOps team.
- Implement a custom Microsoft Sentinel workbook named Workbook1 that will include a query to dynamically retrieve data from Webapp1.
- Implement a Microsoft Sentinel near-real-time (NRT) analytics rule that detects sign-ins to a designated break glass account.
- Ensure that HuntingQuery1 runs automatically when the Hunting page of Microsoft Sentinel in the Azure portal is accessed.
- Ensure that higher than normal volumes of password resets for corp.adatum.com user accounts are detected.
- Minimize the overhead associated with queries that use ASIM parsers.
