eli5: This search returns the number of times, as well as the first and last time,
|
|
it has seen every process run for each endpoint and user, and then displays only
|
|
those processes that you have marked as uncommon in the `uncommon_processes_default.csv`
|
|
table.

|
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 also be
|
|
ingesting logs with both the process name and command line from your endpoints.
|
|
The command-line arguments are mapped to the "process" field in the Endpoint data
|
|
model. This search uses a lookup file `uncommon_processes_default.csv` to track
|
|
various features of process names that are usually uncommon in most environments.
|
|
Please consider updating `uncommon_processes_local.csv` to hunt for processes that
|
|
are uncommon in your environment.
