Secure Score by Groups Workbook

Scenario

The Azure Resource Graph security baseline for Azure Security and the power of Azure Monitor bring you infinite possibilities to custom Azure Security Center information. Consider a scenario where you want to have visibility of the Secure Score for different subscriptions that are in different regions in a single dashboard. This article explains how to leverage Azure Monitor workbooks to create that. The workbook is available in our GitHub community page and the result looks like this:

The queries

This workbook has two queries created using Azure Resource Graph:

One for obtaining the Overall Secure Score of the selected subscriptions
The other obtains the individual Secure Score

To obtain the individual score, use the sample query below:

securityresources
| where type == "microsoft.security/securescores"
| extend subscriptionSecureScore = round(100 * ((todouble(properties.score.current))/ todouble(properties.score.max)))
| project subscriptionSecureScore, subscriptionId
| order by subscriptionSecureScore asc

When you run the query in ARG, you will get a similar result to this:

Behind the scenes, each security control Current Score and Maximum Score is found here:

Query: overall secure score – multiple subscriptions

To get the overall secure score of more than one subscription, you can use the next query:

securityresources
| where type == "microsoft.security/securescores"
| extend subscriptionScore = todouble(properties.score.current)/todouble(properties.score.max)
| extend subScoreXsubWeight = todouble(subscriptionScore)*todouble(properties.weight)
| summarize upperValue = sum(subScoreXsubWeight), underValue = sum(todouble(properties.weight))
| extend overallScore = round(100*((upperValue)/(underValue)))

The result would be similar to this:

The Workbook Visualization

The workbook will show by default four groups. Each group has five variables: group, title, subscription picker, overall secure score, secure score per subscription.
