description: Detect the usage of comsvcs.dll for dumping the lsass process.
|
||||
how_to_implement: You must be ingesting endpoint data that tracks process activity,
|
||||
including parent-child relationships from your endpoints, to populate the Endpoint
|
||||
data model in the Processes node. The command-line arguments are mapped to the "process"
|
||||
field in the Endpoint data model.
