KQL OPERATOR: TAKE
Description:
The take operator in Kusto Query Language (KQL) is used to extract a specific number of rows from a dataset.
For a security analyst working with Microsoft Defender for Endpoint (MDE), this operator is particularly useful for quickly previewing suspicious or relevant network events.
Use-Cases (leveraging the DeviceNetworkEvents Table):
#1 Basic usage:
This command displays the first 5 network events from the
DeviceNetworkEvents table. This gives the analyst a quick overview
overview of the latest network activities.
DeviceNetworkEvents
| sort by Timestamp
| take 5
#2 Search for specific action types:
This gives the analyst the first 5 network events for which the action was
was 'HttpConnectionInspected'. This can be useful to quickly analyse
the latest web activities.
DeviceNetworkEvents
| sort by Timestamp
| where ActionType == 'HttpConnectionInspected'
| take 5
#3 Combined with IP filter:
With this query, the Analyst can display the first 5 network events that
occurred from or to a specific IP address (in this case 192.168.1.1).
have taken place.
DeviceNetworkEvents
| sort by Timestamp
| where RemoteIP == '23.202.169.49'
| take 5
WHEN TO USE IT:
- to get a quick preview of the latest or most relevant network events.
- in combination with filters to identify a limited number of relevant events.
THINGS TO KEEP IN MIND
- The take operator returns the rows in the order in which they appear in the data set. If a specific order is required, you should use the sort operator first.
- When using take in combination with other operators the order is important. The take operator should always be placed after the filter and sort operators.
