description: This search looks for command-line arguments where `cmd.exe /c` is used
|
|
to execute a program, then creates a baseline of the earliest and latest times we
|
|
have encountered this command-line argument in our dataset within the last 30 days.
|
|
how_to_implement: You must be ingesting data that records process activity from your
|
|
hosts to populate the Endpoint data model in the Processes node. You must be ingesting
|
|
logs with both the process name and command line from your endpoints. The complete
|
|
process name with command-line arguments are mapped to the "process" field in the
|
|
Endpoint data model.
