When investigating suspicious PowerShell activity detected by Azure Sentinel, what is a crucial step to take?

In the investigation of suspicious PowerShell activity detected by Azure Sentinel, checking the VM's security logs is a crucial step because these logs provide detailed information about the events that have occurred on the machine, including user activities, executed commands, and system alerts. By examining security logs, you can gather contextual information that can help identify whether the PowerShell activity was legitimate or part of a malicious attack.

Security logs may reveal patterns that indicate unauthorized access or other suspicious behavior, helping to establish a timeline of events leading up to the detection. This analysis can assist in determining the severity of the potential threat and inform the next steps for remediation. Accessing this data is essential to painting a full picture of the incident and making informed decisions regarding necessary responses.

The other activities, while potentially beneficial, do not provide the immediate insights necessary for responding to the alert. For instance, reviewing the VM's network traffic could provide additional context but may not directly address the actions that triggered the alert. Analyzing the PowerShell script for malicious commands is also important, but without context from the security logs, it may be challenging to assess the overall situation. Moreover, ignoring the incident is not advisable, as doing so could leave the system vulnerable to actual threats. Thus,
