IMAP

Version: 1.3
Updated: Mar 4, 2024

Cloud SOAR

This integration is only for Cloud SOAR.

Allows you to connect your mailbox with Cloud SOAR and receive mail via IMAP protocol.

Actions

• Incoming Mail Daemon (Daemon) - Automatically get emails using IMAP and save emails.

IMAP configuration

Get JWT token

1. Collect the JWT token which is required later:

   1. It can be found under the user Profile.
   2. Just copy it temporarily in a text editor.
      

2. To configure the integration, log into the application, expand the configuration menu in the top right corner by hovering over the gear icon and click Automation.
   

3. In the Automation section, on the left menu, click Integrations.
   

4. After the list of the integrations appears, search/look for the integration and click on the row.

5. The integration details will appear. Click on the "+" button to add new Resource.
   

6. Populate all the required fields (*) and then click Save.
   

   • IMAP Server. For example: Imap.gmail.com, Outlook.office365.com, Imap.mail.yahoo.com
   • Mailbox Account. Only required if the Username isn't already an email address (for example: Username: admin, Mailbox Account: admin@test.com).
   • Cloud SOAR User JWT Token. Enter the previously copied token.
   • Email Fetch Type (Daemon).

     • Unseen/Unread. Only fetch the mails which are currently UNSEEN or UNREAD.

     • Fetch From Latest CSOAR Mail. Fetch all mails from the mail server which are not yet stored on Cloud SOAR. For the first time it will fetch UNSEEN mails for the second run/execution. Pre-Filtering options can be used to pre-filter emails in the mail server. Only pre-filtered emails are imported and analyzed by Cloud SOAR.

     • Email Fetch Type and below other filters will be combined with AND operator.

     • Pre-filtered options:

       • From. You can filter email using From or even you can use full Domain name. For example: sumologic.com, sales@sumologic.com. Based on the above example, only the mails coming from Sumo Logic domain or sales@sumologic.com will be fetched. This field accepts multiple values separated by comma. Multiple values will be combined with OR operator.
       • To. Indicate the receiver of the mail, this filter works the same as From filter. This field accepts multiple values separated by comma. Multiple values will be combined with OR operator.
       • Subject. Fetch mails based on Subject. This field accepts multiple values separated by comma. Multiple values will be combined with OR operator.
       • Text Body. Based on text search inside the body even it will work for attachment name. This field accepts multiple values separated by comma. Multiple values will be combined with OR operator.
       • Header. Header string to be searched based on the below filter.
       • Header Field Name To Search in Header. A list from which you can choose a header element where to search the provided value in the previous field.

       Pre-filtered options are also available to filter as NOT condition:

       • Not From
       • Not To
       • Not Subject
       • Not Text Body
       • Not Header
       • Header Field Name To Search in Header

       Similarly to the other pre-filter, but the email elements matching the provided conditions will not be fetched.

       As specified, all filters will be combined with AND operator.
       

7. To make sure the resource is working, hover over the resource and then click the pencil icon that appears on the right.
   

8. Click TEST SAVED SETTINGS.
   

9. You should receive a successful notification in the bottom right corner.
   

Testing Incoming Mail Daemon

It is recommended to test this action before proceeding.

1. Click on the action name.
   
2. Click on TEST ACTION.
   
3. This test action will return some results based on configuration. Once you get the results then it means your IMAP configuration and Mail Daemon are working fine.
   

List Cloud SOAR Emails

You can use the List Cloud SOAR Emails action directly from the Mail Tools integration page:

1. Click on the action.
   
2. Click on TEST ACTION.
   
3. After a moment you should receive the results.
   

Create Custom Fields

Now you have to create two Custom Fields: one for Incident and the other for Triage.

We will need this custom Field in playbook and Incoming events automation Rule mapping.

Follow these steps:

1. Expand the configuration menu in the top right corner by hovering over the gear icon and click Settings.
2. On the left menu expand Customization options.
3. Then click on Fields.
4. Make sure the Triage section is selected.
5. Click on the button to add a new field.
6. Enter the name (for example: CSOAR Email ID).
7. Make sure the Visible option is selected.
8. Click CREATE.
9. Now you should see the new field in the table.
   
   
10. Repeat the same steps from 5 to 9 for the Incidents section.
    

Create an Incident associated with mail

Once IMAP is configured you have the possibility to create an Incident associated with mail.

1. Create a new playbook or you can update the existing playbook.
2. Add Email To Incident action to the playbook. Cloud SOAR Email ID: choose the ID that you created earlier (i.e. CSOAR Email ID from Incident fields).
   
   
3. Now let's expand the playbook by adding the ability to save attachments in the incident. Create a new node of type Action and set the fields as you can see in the following picture.
   
4. Now we need a new node of type Condition.
   
5. Finally add another Action as you can see.
   
6. Below you can see the final playbook.
   
7. Another scenario that could be used with the IMAP mail daemon is to analyze an EML or MSG attachment that is contained in the mail without saving the attachment in the incident. Users can just extract the email with a given email ID. The following example demonstrates that in an incident:
   • Use the same action Add Email to Incident as seen before. This action is used to attach the email to the current incident.
   • Then create Analyze EML MSG action (Mail Tools) .
   • Select what should be parsed from the EML or MSG attachments.
     
8. Below you can see the final playbook.
   

Create an Incident Template

Once the playbook is ready, then you can create an Incident Template.

1. In the Automation section click on Incident templates.
2. Click the button to create a new Template or jump to step 3 if you already have one.
3. Select the template.
4. Click the button to add a new playbook (more than one playbook can added).
5. Search your playbook.
6. Select the playbook(s) you want to add.
7. Click Add.
8. Enable AUTORUN.
   
   
   
   

Create a new Rule

At this point you have to create a Daemon Rule.

1. In the Automation section click on Rules.
2. Click the button to create a new rule.
3. Fill in all the required fields and click SAVE.
4. Next we will create a filter.
5. Click the button to add a filter.
6. After you created the filter click SAVE.
7. Click the button to add a new action.
8. Fill in all the required fields and click SAVE.
9. Click the button and create a new mapping. Daemon Field must be cloud_soar_mail_id and Cloud SOAR Field must be set to a custom field.
10. Finally enable the Rule.
    
    
    
    
    
    
    
    

Email Body Regex

This action allows you to fetch the desired information from the email body using regular expression.

In the following example we add a new node in our playbook giving the following information.

The final playbook looks like this:

• Email: [\w.-]+@[\w.-]+
