For advanced hunting of recent PowerShell activities within your organization's network, which method should be employed using the Microsoft Graph Security API?

The correct approach for advanced hunting of recent PowerShell activities within your organization's network is to utilize the Microsoft Graph REST API, either the v1.0 or Beta version, to submit a KQL (Kusto Query Language) query through the runHuntingQuery method. This method allows analysts to leverage KQL's powerful querying capabilities to effectively sift through the data acquired from various Microsoft security services, focusing specifically on PowerShell activities.

Using KQL for your queries is advantageous because it is specifically designed for querying large datasets and can handle complex queries efficiently, enabling you to filter, sort, and analyze logs in a more granular way. This is particularly important when hunting for specific activities such as PowerShell command executions, as it allows for precise targeting of the data relevant to security investigations. The runHuntingQuery method is a dedicated endpoint in the Graph API designed for such forensic capabilities, making it the best choice for advanced hunting scenarios.

In contrast, other options may not provide the same level of specificity or may require manual intervention that could introduce errors or inefficiencies. For instance, manually searching for recent PowerShell activities (the first choice) can be labor-intensive and lacks the automation and efficiency of a KQL query. Submitting a PowerShell script
