Query
// Use Case: Monitoring and analyzing the execution of processes on a computer to identify and investigate potential security threats or system performance issues.
Process
| project ProcessName, CommandLine, StartDateTime
| where isnotnull(CommandLine) and CommandLine != '' // Filter out empty or null command lines
| order by ProcessName, StartDateTimeExplanation
This query is designed to monitor and analyze processes running on a computer to help identify potential security threats or performance issues. Here's a simple breakdown of what it does:
-
Data Source: It starts by looking at a dataset called
Process, which contains information about processes running on a computer. -
Select Columns: It selects three specific pieces of information for each process:
ProcessName: The name of the process.CommandLine: The command line used to start the process.StartDateTime: The date and time when the process started.
-
Filter: It filters out any processes where the
CommandLineis either empty or null, meaning it only keeps records where there is a valid command line entry. -
Sort: Finally, it sorts the remaining processes first by
ProcessNameand then byStartDateTime, organizing them in alphabetical order by process name and chronological order by start time.
Overall, this query helps in reviewing and investigating the processes that have valid command lines, making it easier to spot unusual or suspicious activities.
