Prerequisites

You can find the system requirements for each respective platform below :

• Windows Requirements
• Windows Server Requirements
• MacOS Requirements

Warning

It's also necessary to know that you have to install Sophos agents on the necessary machines.

Create Sophos Threat Analysis Center Credentials

In the Sophos Central Admin console:

1. Go to Global Settings > API Credentials Management.
2. Click Add Credential and give the credential a name and description.
3. Choose which role you want to assign. You can choose from the following roles:
   • Service Principal Super Admin: Users with this role can perform all API operations with full CRUD (Create Read Update Delete) capabilities and have access to queries.
   • Service Principal Forensics: Users with this role can create, view, run, and delete Live Discover queries.
4. Click Add.

This generates the credential, together with a Client ID and a Client Secret. Copy the Client ID and Client Secret.

Enable logs to Sophos data lake

By default sophos central will not send logs to the Data Lake automatically, so you have to do it manually. you will need to enable hydration for both Endpoints and Servers as you want.

To enable hydrating the data lake for endpoint:

1. Click Endpoint Protection
2. Click Settings
3. Scroll down and click Data Lake uploads
4. Toggle the switch to enable Upload to the Data Lake
5. (OPTIONAL) - if you want to exclude any devices, select them from the available list and move them to the excluded list

To enable hydrating the data lake for server:

1. Click Server Protection
2. Click Settings
3. Scroll down and click Data Lake uploads
4. Toggle the switch to enable Upload to the Data Lake
5. (OPTIONAL) - if you want to exclude any devices, select them from the available list and move them to the excluded list

Create the intake

1. Go to the intake page and create a new intake from the format Sophos Analysis Threat Center.
2. Copy the associated Intake key

Pull events

1. Go to the Playbook page.
2. Click on + PLAYBOOK and choose Create a playbook from scratch.
3. Give it a name and a description and click on Next.
4. In Choose a trigger, select the Query IOC from data lake.
5. Click on the Query IOC from data lake module on the right sidebar and in the Module Configuration section, select Create new configuration.

6. Write a name and paste the client_id and client_secret from the Sophos console and click on Save.

   Info

   • If you want to change the region with your own region, you can find your region via protect devices field, first click on Protect Devices, Then copy link of any download links and finally Check the region that appears as part of the URL.
   • No need to change the Oauth2 Authorization Url for the moment (this's the only endpoint to get a JWT token).

7. In the Trigger Configuration section, click on Create new configuration.

8. Write a name, choose a frequency - Default is 60 -, paste the intake_key associated to your Sophos Threat Analysis Center intake and click on Save.
9. On the top right corner, start the Playbook. You should see monitoring messages in the Logs section.
10. Check on the Events page that the Sophos logs are being received.
