Agent Management
Agents are services that run on an external server. They act as a liaison between the server and the D3 SOAR Platform to ensure security and stability for data ingestion.

The Agent Management module allows you to quickly manage, deploy, update and monitor Agents in the D3 SOAR Platform. Once installed, the Agents will be listed on the left side with details such as Agent Name, Description, Version, Site and Status. You can click on any Agent from the list to view its status, version, service URL, location, host, IP and Mac Address in the right-side panel.
Proxy Agent Overview
D3 Proxy Agent is used to assist the communication (1) between D3 Web Server and certain integrations sitting in a local environment for the SaaS solution or (2) between D3 Web Server and certain integrations sitting in a separate environment disconnected from the environment (via Internet) where Web Server is sitting for the On-Premises solution.

Figure 2: D3 SOAR Proxy Agent Architecture Diagram for On-Premise Implementation
D3 SOAR’s proxy agent needs to be installed in the local environment to initiate the connection to the D3 SOAR web server. After a connection has been established, the D3 SOAR web server will be able to send a request to the proxy agent, then pass the request to integrations installed on a separate environment. The integrations will send responses back to the D3 SOAR web server via the proxy agent.
D3 Proxy Agent was previously hosted in a Windows container. From v15 onwards, it is hosted in a Linux container. D3 is supporting the docker installed on Ubuntu or Red Hat.
Proxy Agent Version Compatibility
Alert
It is important to avoid installing incompatible versions of the agent and executor when updating your instance of D3 SOAR, as it may lead to issues. Ensure you update the agent (applicable to both SaaS and on-premises deployments) and executor (only for on-premises deployments) versions to the matching D3 SOAR release version. This release version can be found on the sign-in page of D3 SOAR.

Task 2: Authenticate to Google Container Registry
The D3 Proxy Agent image hosted on Google Container Registry is private. Authenticate to the D3 Google Container Registry to pull and install it.
Contact the D3 account representative to obtain the
service_account_d3soar.json
file. Ensure that the file name remains asservice_account_d3soar.json
without any appended parentheses or numbers.Create a directory for the D3 Proxy Agent installation on the Linux host machine:
mkdir D3ProxyAgent
Change to the newly created directory:
cd D3ProxyAgent
Copy the
service_account_d3soar.json
file into the newly created directory.Authenticate to the Google Container Registry using the following command:
sudo docker login -u _json_key --password-stdin https://gcr.io < service_account_d3soar.json
READER NOTE
Successful authentication will result in a “Login Succeeded” message in your terminal.
WARNING
The
service_account_d3soar.json
file must be named exactly asservice_account_d3soar.json
without any changes to its name.If you encounter errors, verify the naming and content of your
service_account_d3soar.json
file.
(Optional) Test and verify that you can successfully pull an image from the D3 Google Container Registry by running the following command:
sudo docker pull gcr.io/nimble-cortex-285618/d3prod/d3agent:<D3 vSOC version>
READER NOTE
The
<D3 vSOC version>
conforms to the following format:#.#.#.#
(Eg.16.8.112.0
).The
<D3 vSOC version>
can be found within your D3 vSOC login page.Upon a successful pull, you will see something like the following:
Upon a failed pull, you will see a “Failed to fetch
<D3 vSOC version>
from request...” message:
Task 3: Run docker-compose to Start the Containers
On the Proxy Agent, we will need to run both the d3executor and the d3agent containers.

restart: always
environment:
- EXECUTOR_GUID=7e036a86dbee40d9913c3794e779eae4
Create a
docker-compose.yml
file using the template above.The
<Agent Version Number>
,<D3 vSOC URL>
,<D3 vSOC Agent Token>
,<Docker Host IP>
,<Docker Host Port>
,<Proxy Agent Display Name>
,<Docker Group ID>
, and<Executor Version Number>
must be replaced with specific values.Ensure that the version numbers for your compatible agent and executor match the version number of your D3 vSOC instance. Replace
<Agent Version Number>
and<Executor Version Number>
with the corresponding version numbers. For example, if you are using D3 SOAR release version 16.1.80.0, set both the<Agent Version Number>
and the<Executor Version Number>
to 16.1.80.0.The
D3 vSOC Agent Token
can be generated by following these steps:1. Navigate to the the Configuration navigational tab.
2. Click on the Agent Management menu item on the left sidebar
3. Click on the + Generate Security Token button.
4. Select your site from the dropdown menu.
5. Click on the Generate Key button.
6. Click on the Copy button, then paste the security token into thedocker-compose.yml
file.The
<Docker Host IP>
refers to the private IP address of the Linux machine hosting Docker. You can find this address using the command ip addr show on Linux. Ensure that the port is accessible and not being used by any other program.The
<Docker Host Port>
specified in thePYTHON_REMOTE_URL
environment variable of thed3agent
service must match the<Docker Host Port>
specified in theports
mapping of thed3executor
service. This ensures proper communication between thed3agent
andd3executor
services.Run the following command in your Linux machine, where the Docker is hosted, to find your
<Docker Group ID>
:
getent group docker | cut -d: -f3
You will see something like the following:
![Frame 8 (3)-20240715-193954.png](../../__attachments/221609985/Frame%208%20(3)-20240715-193954.png?inst-v=526df509-4082-416f-8021-e6d677041253)
In this example, the <Docker Group ID>
is 999.
Open a terminal and navigate to the directory where the
docker-compose.yml
file. Once there, execute the following command:
sudo docker compose up -d
Upon successfully bringing up the Docker Compose services, your terminal will display outputs similar to the following:
![Frame 4 (3)-20240709-230040.png](../../__attachments/221609985/Frame%204%20(3)-20240709-230040.png?inst-v=526df509-4082-416f-8021-e6d677041253)
Firewall Whitelisting for Docker Installation and D3 Proxy Agent Container Image
If all internet traffic is blocked by default, then certain Domains/IPs will need to be whitelisted in order to be able to download the docker package as well as the images hosted on GCR.
1. Sites that require whitelisting
Docker (for downloading docker package):
download.docker.com
GCR (for downloading docker images from GCR):
gcr.io
storage.googleapis.com
2. Example of Checking IP address
Use nslookup to check IP address of the domain that needs to be accessed
![](../../__attachments/221609985/att_60_for_15007789.png?inst-v=526df509-4082-416f-8021-e6d677041253)
We can see that download.docker.com
has a few IP addresses that it uses. We can allow traffic to this domain download.docker.com
or to an IP address list that includes all the resolved public IP (the same domain may resolve to different public IP from different regions, if you use IP address for the whitelist, you need to run nslookup to get these IP from your server.)
Using D3 Proxy Agent with a Web Proxy Server
![](../../__attachments/221609985/att_29_for_15007789.png?inst-v=526df509-4082-416f-8021-e6d677041253)
To route D3 Proxy Agent’s outbound internet connections to a web proxy server, make the following configuration changes.
Open docker-compose.yml
. Add the following to the Environment section:
HTTP_PROXY=<Web Proxy Server:Port>
HTTPS_PROXY=<Web Proxy Server:Port>
NO_PROXY=localhost,127.0.0.1,<Docker Host IP>,<Other local integration host address,...>
docker-compose.yml
version: "3.3"

ports:
- "<Docker Host Port>:9090"
restart: always
environment:

- HTTP_PROXY=<Web Proxy Server IP:Port>
- HTTPS_PROXY=<Web Proxy Server IP:Port>
- NO_PROXY=localhost,127.0.0.1,<Docker Host IP>,<Other local integration host address,...>
HTTP_PROXY
and HTTPS_PROXY
are going to be the web proxy server HTTP and HTTPS connections respectively. You will need to add more addresses for the private IP, DNS name, and all other local integrations you want to connect to (i.e. skipping the proxy) to the NO_PROXY
.

Proxy Agent Windows Server Hardening
How Proxy Agent Works
![](../../__attachments/221609985/att_50_for_15007789.png?inst-v=526df509-4082-416f-8021-e6d677041253)
In short, the Proxy Agent does NOT need incoming TCP connections. It always initiates TCP connections to vSOC server and RestfulAPI targets. So we can block all incoming connections to the Windows server where D3 Proxy Agent is running on. Just run the powershell scripts to disable all the default enabled incoming firewall rules on Windows Server.
![](../../__attachments/221609985/att_9_for_15007789.png?inst-v=526df509-4082-416f-8021-e6d677041253)
![](../../__attachments/221609985/att_22_for_15007789.png?inst-v=526df509-4082-416f-8021-e6d677041253)
Troubleshooting
Package download is NOT successful
Agent Key
Download PlaybookAgent from vSOC GUI. The file size of D3PlaybookAgentInstaller14.0.xxx.x.zip should be at least 170MB or larger which includes the Python package. If the download does NOT include the Python package, its size may be around 3MB and requires troubleshooting.
On DB Server, in SSMS (SQL Server Management Studio), right click the database, run new query
Run the following command to check if the Proxy Agent key exists or not.
select * from vSOC_Settings_Default where keyname like 'Cyber.PythonInstallationFolderForPlaybookAgent'
If the PlaybookAgent key does not exist, run the insert command to add it to the database.
insert into vSOC_Settings_Default (keyName, keyValue) values ('Cyber.PythonInstallationFolderForPlaybookAgent', 'C:\Python\Python38')
Run the update command to update the key value.
update vSOC_Settings_Default set keyValue = 'C:\Python\Python38' where keyname like 'Cyber.PythonInstallationFolderForPlaybookAgent'
READER NOTE
C:\Python\Python38
is an example here.
It is the Python path on your vSOC server. Change it to your Python path where Python.exe resides.
After updating the key into the Database, stop D3TaskManager services, stop App Pool, then restart the services and App Pool again.
Delete Agent folder under
C:\D3App\D3Temp\Agent
orC:\D3App\Virtual_Dir\D3Temp\Agent
See examples below. Your D3App folder may be on other disks like D:\ or E:\ as well.
![](../../__attachments/221609985/att_10_for_15007789.png?inst-v=526df509-4082-416f-8021-e6d677041253)
![](../../__attachments/221609985/att_23_for_15007789.png?inst-v=526df509-4082-416f-8021-e6d677041253)
No File Downloaded
When attempting to download the Agent, sometimes no file is downloaded. In this case, check your D3Temp directory properties. Make sure users have full control so the Agent software can be written into this folder.
Set users with full control.
Go to vSOC to download the agent again. The correct zipped installation package size should be at least 170MB or larger.
READER NOTE
If user vSOC was updated to a new version, you need to download and update your Proxy agent accordingly.
The Proxy Agent version should match the vSOC version.
Download new Proxy Agent and install
READER NOTE
You can install multiple Proxy Agents, each with a different Security Token.
Installing Agent Not Completing
If the installation stalls and does not complete, the root cause is that the Playbook Installation package was blocked by Windows when downloading from vSOC servers.
![](../../__attachments/221609985/att_24_for_15007789.png?inst-v=526df509-4082-416f-8021-e6d677041253)
Go to the .zip file and view Properties
Check the Unblock box before unzipping the file. Even if the file is able to unzip successfully without this permission, some files will still be blocked by Windows. Ensure that this is checked before proceeding.
Run the installation again

Network Configuration for D3 Application in Restricted Client-Side Environments
To ensure the proper functioning of the D3 application in a client-side network with default outbound traffic restrictions, please perform the following steps:
Ping the D3 application URL (e.g., smartsoar.d3securityonline.com) to determine the required inbound IPs.
Whitelist the identified inbound IPs on your firewall's outbound rules. This step will allow the necessary communication between the D3 application and the external network.
Please note that these steps should be followed in the following scenarios:
When the D3 proxy agent is installed in a client-side network that blocks outbound traffic to the internet by default.
When client users are accessing the D3 application within a client-side network that denies outbound traffic to the internet by default.
