Overview

Cloud Exchange CTE’s integration with Trend Micro Vision One gives you the ability to bilaterally share indicators of compromise (IOCs) in the form of URLs and file hashes.

Trend Micro Vision One setup steps

Finding your Regional URL

When you log into your Trend Micro portal, the URL will have a “Data Region” right before xdr. In my example I have “in” or India as my region. Note down your region. 

 

The options are: 

Australia - au

European - eu

India - in

Japan - jp

Singapore - sg

UAE - uae 

 

portal.in.xdr.trendmicro.com

Netskope Cloud Exchange setup steps

Cloud Exchange Plugins

On your, Netskope Cloud Exchange go to Settings > Plugins

You will need two plugins configured for this solution. The Netskope CTE  plugin and the Trend Micro Vision One v1.0.1 CTE plugin. 

If you need to update your plugins go to the Plugin Repository tab and select ‘check for updates’.

Create a Cloud Exchange Business Rule

On your Cloud Exchange interface go to Threat Exchange > Business Rules

Select Create New Rule

You can bring in URLs and file hashes with one rule or break up into two.

Sharing Configuration

Now that you have the plugins configured and the business rules in place, the next step is to tell Cloud Exchange which products you would like to share the threat IoCs with. The source field will be where the IoCs are coming from and the destination field is where they will go. The business rule will act as a filter for what you are sharing. If you want bidirectional sharing, you will need two sharing rules. 

Threat Exchange > Sharing > Add Sharing Configuration

Sharing Hashes to Netskope

When sharing hashes to Netskope it will ask you for a List Name. This name needs to be set on the Netskope Tenant side also. 

  • See below on how to configure your Netskope tenant’s List Name

Create File Profile Policy

To configure the file location in your Netskope Tenant (not in Cloud Exchange) go to Policies > File > New File Profile

Go to File Hash and drop down the Add File Hash by Type and select your sharing type. I selected SHA256 for Trend Micro Vision One. 

>Next

Give it a name and Save

This file name will be the “List Name” that you will use in Cloud Exchange.

Create New Malware Detection Profile

Go to Policies > Threat Protection > New Malware Detection Profile

GaryJenkins_16-1672415167237.png

 

Click Next to get to the Blocklist page and select the File Profile you created. Scroll to the bottom and select Next

Add a Profile Name, review your blocklist and Save Malware Detection Profile

GaryJenkins_18-1672415167122.png

 

Add a Real-time Protection Policy

Go to Policies > Real-time Protection > New Policy

In my example, I selected a Threat Protection policy

GaryJenkins_19-1672415167287.png

 

Under Profile & Action select Add Profile > Threat Protection Profile

For the Action you will want to Block and select a template of what the user will see when the file is blocked. 

GaryJenkins_20-1672415167266.png

 

Select the Threat Protection Profile you created. Adjust the Severity-Based Actions as needed for your configuration.

Give your policy a name (Set Policy) and Save

Verify Integration

Verify Sharing of IoCs. 

Go to Threat Exchange > Threat IoCs

On this page you will see a list of all IoCs that are coming into Cloud Exchange. If they have come from Netskope they will be counted on the Total Netskope Hits and if they came from a 3rd party plugin (like Trend), they will be counted until Total Other Hits. To see additional details click the arrow on the right. You will be able to see things like when it was seen and which 3rd party plugin came from. 

GaryJenkins_22-1672415167296.png

 

 

Trend has a cool feature that lets you easily add an IoC. Go to Threat Intelligence > Suspicious Object Management > Add. If my above Netskope picture is clear enough, you will notice that the two IoCs I created below are the ones showing up in Cloud Exchange. 

GaryJenkins_23-1672415167094.png

 

 

On your Netskope Tenant go to Policies > File and then to the File Profile you created and you should see your file hash under the File Hash tab.
