Understanding Microsoft 365 Security Posture Monitoring

Automated Microsoft 365 Security Posture Monitoring with Maester helps you set up an automation solution for monitoring your Microsoft 365 Security Posture using the Maester tool with Azure Automation. This solution eases the process of deploying and managing security assessments.

To get started with the Maester PowerShell module, you need to install two dependencies: Microsoft.Graph.Authentication and Pester. These are crucial for obtaining access tokens for Microsoft Graph and for leveraging a testing framework for PowerShell, respectively. Installing these modules is straightforward with provided PowerShell commands.

Running a Microsoft 365 security report is simplified with predefined security assessments. Connection to Microsoft Graph is facilitated through Connect-Maester, a custom cmdlet designed to ease the process with predefined scopes. This enables a smooth and effective security evaluation.

An important step in the automation process is granting the necessary permissions to the Managed Identity created with the Automation Account. This step is crucial for the Maester report to run using the Managed Identity. Subsequent steps involve loading PowerShell modules and creating a new Runbook for generating and emailing the security report.

  • Creating an Automation Account
  • Assigning permissions to the System-assigned managed identity
  • Loading the required PowerShell modules
  • Creating a new Runbook

To automate the report, Azure Automation and other DevOps services like Azure DevOps and GitHub Actions can be utilized. Automating the report involves a few steps starting from creating an Automation Account to defining the report schedule. This process ensures efficient and regular security assessments.
