// Title: Blackberry CylancePROTECT
|
||||||
|
// Author: Microsoft
|
||||||
|
// Version: 1.0
|
||||||
|
// Last Updated: 12/04/2020

// Comment: Initial Release

|
||||||
|
// DESCRIPTION:
|
||||||
|
// This parser takes raw CylancePROTECT logs from a Syslog stream and parses the logs into a normalized schema.
|
||||||
|
//
|
||||||
|
// USAGE:
|
||||||
|
// 1. Open Log Analytics/Azure Sentinel Logs blade. Copy the query below and paste into the Logs query window.
|
||||||
|
// 2. In the query window, on the second line of the query, enter the hostname(s) of your CylancePROTECT device(s) and any other unique identifiers for the logstream.
|
||||||
|
// For example: | where Computer in ("server1", "server2")
|
||||||
|
// 3. Click the Save button above the query. A pane will appear on the right, select "as Function" from the drop down. Enter a Function Name.
|
||||||
|
// It is recommended to name the Function Alias, as CylancePROTECT
|
||||||
|
// 4. Kusto Functions can typically take up to 15 minutes to activate. You can then use Function Alias for other queries.
|
||||||
