Explanation
This KQL (Kusto Query Language) query is designed to help identify potential security risks related to Microsoft Cloud Platform (MCP) implementations. Here's a simple breakdown of what the query does:
-
Data Source: It looks at the
DeviceNetworkEventstable, which contains information about network-related events on devices. -
Time Filter: The query filters the data to only include events that occurred within the last hour (
TimeGenerated > ago(1h)). -
Action Type: It specifically searches for events where a "ListeningConnectionCreated" action occurred. This means the device has opened a network port to listen for incoming connections.
-
Port Filter: It further narrows down the results to only include events where the local port being listened on is port 5008 (
LocalPort == 5008). -
Process Filter: Finally, it checks if the command line of the process that initiated the listening connection includes the term "azure/mcp". This suggests that the process is related to Azure MCP.
In summary, this query is used to detect recent network events where a device has started listening on port 5008 for connections, specifically related to Azure MCP processes. This can help in identifying and mitigating potential security risks associated with MCP implementations.
