Create an Event Log Query

From the

Query Builder

you can search Windows and Linux event log attributes and investigate event logs across endpoints with an Cortex XDR agent installed.

Some examples of event log queries you can run include:

Critical level messages on specific endpoints.
Message descriptions with specific keywords on specific endpoints.

To build a file query:

From Cortex XDR, select
INVESTIGATION
Query Builder
.
Select
EVENT LOG
.
Enter the search criteria for your Windows or Linux event log query.
Define any event attributes for which you want to search. By default, Cortex XDR will return the events that match the attribute you specify. To exclude an attribute value, toggle the
=
option to
=!
. Attributes are:
PROVIDER NAME
—The provider of the event log.
USERNAME
—The username associated with the event.
EVENT ID
—The unique ID of the event.
LEVEL
—The event severity level.
MESSAGE
—The description of the event.
To specify an additional exception (match this value except), click the
+
to the right of the value and specify the exception value.

Optional
) Limit the scope to an endpoint or endpoint attributes:
Select and specify one or more of the following attributes:
HOST
—
