ACS Dashboard in OMS: Your Audit Report Highlights in a Glance

Artikel
08/16/2016

This post demonstrates how the OMS Log search queries listed in the mapping table for each ACS Audit Report can be used to drive visualizations for an OpsMgr Featured Audit Collection Services (ACS) Dashboard based on the security events collected by the Security and Audit Solutions in OMS Log Analytics.

The ACS Summary Tile and Dashboard can be configured using the OMS View Designer feature in your OMS Log Analytics workspace. Adding the Security and Audit solution to an OMS workspace will allow Windows security events, Windows application events, and Windows firewall logs to be collected using direct agents or MMA agents that the user enabled.

Here are the steps to create the Summary Tile for the ACS Dashboard, and the Visualization Parts (Views) in the Dashboard Overview that provides a highlight for each ACS Audit Report using the log search queries listed in the mapping table:
(Note: Total time to create the ACS Dashboard in your OMS workspace using the View Designer may take up to 2 hours.)

Step 1: Create the ACS Summary Tile

Preferred Tile Type: Two Timelines Tile
Explanation: To compare the total number of security events collected by the Security and Audit Solution with all the security events that are reported by the ACS Audit Reports, in total and over the last 7 days.
Configuration Overview:

Chart query for all security events (ALL SEC EVENTS):
SecurityEvent
| where EventID!=0
Chart query for ACS focused security events (ACS SEC EVENTS):
SecurityEvent
| where EventID==539 or EventID==644 or EventID==4740 or EventID==6279 or EventID between(529 .. 537) or EventID==539 or EventID==4625 or EventID==4728 or EventID==4732 or EventID==4756 or EventID==632 or EventID==636 or EventID==660 or EventID==4729 or EventID==4733 or EventID==4757 or EventID==633 or EventID==637 or EventID==661 or EventID==4723 or EventID==4724 or EventID between(627 .. 628) or EventID==624 or EventID==630 or EventID==4726 or EventID==4720 or EventID==576 or EventID==4672 or EventID==643 or EventID==4739 or EventID==612 or EventID==4719 or EventID==4670 or EventID between(608 .. 609) or EventID between (621 .. 622) or EventID between (4704 .. 4705) or EventID==516 or EventID==4612 or EventID==517 or EventID==1102 or EventID==560 or EventID==567 or EventID==4656 or EventID==4663 or EventID==576 or EventID==4672 or EventID between(4727 .. 4735) or EventID==4737 or EventID between(4754 .. 4758) or EventID between(631 .. 639) or EventID==641 or EventID between (658 .. 662) or EventID==528 or EventID==540 or EventID==4624
Calculation Operation: Sum
Time Interval Duration: 7 days

Step 2: Create the Further Information and Forensic Views in the Dashboard Overview

Query 2 Friendly Name: All Events For Specified Computer grouped by Activity
Query 2 Search query:
let computerName = “”; //Enter a Computer Name
SecurityEvent
| where Computer==computerName
| summarize count() by Activity
Query 3 Friendly Name: All Events For Specified User
Query 3 Search query:
let accountName = ""; //Enter a User Domain\\Account Name
SecurityEvent
| where Account == accountName
Query 4 Friendly Name: All Events For Specified User grouped by Activity
Query 4 Search query:
let accountName = ""; //Enter a User Domain\\Account Name
SecurityEvent
| where Account == accountName

Query 7 Friendly Name: All Events With Specified Event ID grouped by Account
Query 7 Search query:
let eventId = 0; //Replace 0 with an eventId
SecurityEvent
| where EventID == eventId
| summarize count() by Account
