Sophos Mac Endpoint: How to Configure JAMF Privacy Preferences for 10.15+ Compatibility

Disclaimer: This information is provided as-is and should be referenced at your own risk.


Overview

This article describes the steps to configure JAMF to allow configure permissions for Sophos Mac Endpoint on macOS 10.15+

Applies to the following Sophos products and versions
Sophos Central Mac Endpoint 10.0.0 and above,
Sophos Central Intercept X 10.0.0 and above,
Sophos Central Device Encryption 1.5.2 and above,
Sophos Anti-Virus for Mac OS X 9.9.7 and above

Technical Context

With macOS 10.13, Apple introduced a new security level that required each 3rd party vendor's kernel extension to be approved. This required Team ID to be allowed, also known as the Apple Developer ID.

With macOS 10.15, Apple added a new default behavior that prevented applications from writing to the disk.

The information below covers both topics:

  1. Allowing the Sophos Team ID (2H5GFH3774)
  2. Granting the disk access for each required process

To alert and inform users, Sophos implement a notification popup. The endpoint will check after each reboot (and continuously every 30 minutes) if the system permissions are compatible.

  • This following steps can also be applied to machines running macOS 10.14.x. You may want to prepare your devices to be ready for an upgrade to macOS 10.15+. The instructions below can be followed to prepare device profiles for a future macOS 10.15+ upgrade.

Note: In Sophos for Mac 9.9.5, a notice is displayed if required permissions are not fully enabled. On October 31st, an issue was found where the notice is triggered if the permissions have been added via an MDM profile, as Apple records these in a different location. Sophos is actively working on updating the detection to correct this.

What to do

There are 2 steps required to configure compatibility for macOS 10.15.x (Catalina) and below.
Note: One additional step is required if you want to apply the profile to a macOS 11 (Big Sur) device.

  • Grant full disk access for Sophos components
  • Allow the Sophos kernel extensions
  • (Big Sur - macOS 11) Configure the system extension at the last step. 

Grant full disk access for Sophos components

  1. Open JAMF and log in.
  2. Go to Computers > Configuration Profiles
  3. Create a new Configuration Profile, or select an existing one
  4. Select Privacy Preferences Policy Control (near the bottom of the list)
  5. Click the + beside App Access



  6. In Identifier and Code Requirement put in all the entries listed below, and for Identifier type, select BundleID.
    Note: Sophos does not recommend using the path based format

    Identifier Code Requirement Valid Since Product

  7. In Code Requirement, this can also be self-generated. Run the following on a Mac with version 10.0.0 (Sophos Central) and above:
     
    codesign --display -r - <app path from table above>
  8. Once it has been added, permissions can be selected accordingly. Each one should be given "All Files" / "SystemPolicyAllFiles" as the access.
  9. Save and deploy the configuration as needed.

Allow the Sophos Kernel Extensions

The same profile can be used, but the option "Approved Kernel Extensions" needs to be selected. If this is not configured yet, select the "open" button at the center to begin the configuration.

During configuration, 3 kernel extensions will need to be added, as well as the Sophos Team ID [2H5GFH3774]

Note: Please ensure that "Allow users to approve kernel extensions" is unchecked.

Referring to the screenshot above, add the following kernel extensions:

  • com.sophos.nke.swi
  • com.sophos.kext.sfm
  • com.sophos.kext.oas

Make sure to save your changes.

(Big Sur - macOS 11) Configure the system extension

The same profile configuration can be used.

  1. From the Options, select “System Extensions”.
    1. This step is similar to the ones above, but for the new system extensions
  2. The following empty template will be displayed
  3. For the display name, specify the following entries
    1. com.sophos.endpoint.networkextension
    2. com.sophos.endpoint.scanextension
  4. Add 1 entry for each. Make sure that the System Extension Types are set to “Allowed System Extensions
    1. The picture displays a complete profile example. For the Team Identifier, specify the Sophos Team ID [ 2H5GFH3774 ]
  5. Reference the following screenshot for an example of the Options overview
  6. Don't forget to save your changes

Alternate method

Note: Sophos does not guarantee the security of third party applications and they should be used at your own risk.

There is a utility called PPPC Utility on Github which allows you to build a configuration profile for Privacy Preferences. It can be located here: https://github.com/jamf/PPPC-Utility.  To use this, follow the guidance on the link, and drag and drop the Sophos items into it.

This profile can then be loaded into JAMF.
