Arctic Wolf Agent installation on macOS

Arctic Wolf® Agent is an endpoint security management tool that functions as a component of the following solutions:

• Managed Detection and Response (MDR) — Agent forwards security-relevant event and audit logs from endpoint devices in your network to Arctic Wolf to support continuous threat monitoring.
• Managed Risk — Agent creates an inventory of endpoint devices in your network and performs routine host vulnerability scans and security control benchmark scans to identify security risks. See Arctic Wolf Agent Scans for more information.

You can bulk install Agent on macOS computers across your organization using Jamf Pro software.

Requirements

• macOS 10.14 or newer for 64-bit systems

• At a minimum, dual-core CPU

• x64 or x86 processor

• At a minimum, 2 GB of memory

  Notes:

  • Although Agent is designed to maintain a minimal footprint on all systems, Arctic Wolf recommends certain operating system requirements. Arctic Wolf cannot guarantee Arctic Wolf Agent functionality on virtual machine (VM) environments if resources do not meet recommended levels.
  • Agent does not support ARM architecture.

• Ports 443 and 1514 outbound open

• Add all necessary Arctic Wolf Agent DNS entries to your allowlist. To see the complete list of IP addresses that you must allowlist, go to the Arctic Wolf Unified Portal, and then click Help > Allowlist Requirements. The IP addresses that must be allowlisted are listed under Agent.

  Note: Agent must contact Arctic Wolf servers to register. If this process fails, Agent retries every 15 seconds. This has no negative impact on the system.

• Administrator permissions or the ability to perform administrator or root level functions

Install Agent using Jamf Pro

1. Install Rosetta 2.

   Note: For compatibility, Rosetta 2 is required on ARM-based processors (M1 and M2 based CPUs) before Agent is installed.

2. Download the Agent installer.

3. Create an Agent package.

4. Create a new policy.

5. Configure the policy settings.

6. Configure the package settings.

7. Verify that Agent was successfully deployed.

Step 1: Install Rosetta 2

1. Open Jamf Pro and authenticate.
2. At the top of the page, click Computers.
3. Click Policies.
4. Click + New.
5. Click the Options tab.
6. In the navigation menu, click Files and Processes.
7. In the Execute Command section, enter the following:

   usr/sbin/softwareupdate --install-rosetta --agree-to-license

8. Click the Scope tab.

Step 2: Download the Agent installer

1. In the Arctic Wolf Portal, click Accounts > Downloads.
2. Under Endpoint Agent, select the desired Operating System option.
3. Click Download Agent.

Step 3: Create an Agent package

Before you install Agent, you must package Agent with the customer.json file and a shell script that runs the package installation on each device.

1. Create a new shell script file to run the package installation:

   1. In terminal, create a file called install_AWNAGENT.sh using an editor such as vim.
   2. Add this content to the file:

      #!/bin/sh
      sudo installer -pkg /private/tmp/AGENT/ArcticWolfAgent.pkg -target /
      exit 0

   3. Save the file in any location.

2. Create a new package using a snapshot:

   Tip: Before you begin, we recommend that you make sure your Mac software is up-to-date.

   1. Open Jamf Composer and authenticate.

   2. In the menu bar, click New.

      The Choose a method to create your package dialog appears.

   3. Click Normal Snapshot.

   4. Click Next.

   5. In the Package Name field, enter a name for the new package.

      For example, NewAgentPkg.

   6. Click Next.

   7. Wait for the first snapshot to complete.

      Note: Do not perform any updates, installations, uninstallations, or other configuration changes to your computer while the snapshot is running.

   8. Click Create Package Source.

   9. Wait for the second snapshot to complete.

      Note: If your computer updated or changed between snapshots, Jamf Composer shows you the items that changed. To delete changes from the snapshot, right-click the top file folder of any change and select Remove <folder>. This does not delete them from the computer; it removes them from the package so that it is empty.

3. Configure the /private/tmp/AGENT directory in the new package:

   1. In Jamf Composer, select the package you created in the previous step, for example, NewAgentPkg, to open it in the folder panel.

   2. Click File > Create New Directory.

      

   3. Enter the name private for the directory.

   4. Right-click private, and then select Create New Directory.

   5. Enter the name tmp for the directory.

   6. Right-click tmp, and then select Create New Directory.

   7. Enter the name AGENT for the directory.

4. In Finder, find and then drag each of the following files into the newly created /private/tmp/AGENT directory:

   • .pkg — This file is included in the Endpoint Agent .zip file that you downloaded from Arctic Wolf Portal. Rename the .pkg file to match the package name that you used in the sudo command at the beginning of this procedure, for example ArcticWolfAgent.pkg.
   • customer.json — This file is included in the Endpoint Agent .zip file.
   • install_AWNAGENT.sh — This file was created at the beginning of this procedure.

5. Verify that for Owner: root and Group: wheel, the following R, W, and X permissions are set for the following:

   • private, tmp, and AGENT directories

   • pkg, customer.json, and install_AWNAGENT.sh files

Agent deactivation

You can deactivate Agents by removing them from the Endpoints table in the Arctic Wolf Portal. We recommend uninstalling Agents before deactivating them. If you deactivate an Agent that is still installed on a system, the endpoint reappears in the Endpoints table the next time that it is Online.

Deactivating an endpoint does not delete existing data from Arctic Wolf internal databases.

Contained Agent deactivation

You are not required to deactivate Agents if they are contained. We recommend keeping Agents in the Endpoints table until the containment incident is resolved.

You can remove contained endpoints from the Endpoints table once the incident is resolved and the Agent is uninstalled from the device.

Automatic Agent deactivation and activation

Any devices that were not Online for 90 days are automatically removed from the Endpoints table. The endpoint automatically reappears in the table the next time that Agent detects it as Online.

Deactivate an Agent

If you are a Managed Risk (MR) customer, you can deactivate devices in the Arctic Wolf Portal. If you cannot access the Arctic Wolf Portal, contact your Concierge Security Team (CST).

1. Confirm that the Agent is uninstalled from the device.

2. On the Arctic Wolf Portal, click Endpoint Status.

3. In the Endpoints table, click Remove offline endpoint on the appropriate device.

   Tip: You can only remove devices that are Offline. The Agent only identifies devices as Offline if the Agent did not check in with them for 72 hours.

4. In the dialog, click Remove Endpoint.

   Note: If you accidentally remove an endpoint, the endpoint automatically reappears in the table the next time that Agent detects it as Online.
