Cortex XDR provides full visibility into encrypted Windows and Mac endpoints that were encrypted using BitLocker and FileVault, respectively. Additionally, you can apply Cortex XDR Disk Encryption rule on the endpoints by creating disk encryption rules and policies that leverage BitLocker and FileVault capabilities.
Before you start applying disk encryption policy rules, ensure you meet the following requirements and refer to these known limitations:
Requirement / Limitation
Disk Encryption Scope
You can enforce XDR disk encryption policy rules only on the Operating System volume.
Group Policy configuration:
Follow this high-level workflow to deploy the Cortex XDR disk encryption in your network:
Monitor the Endpoint Encryption Status
You can monitor the Encryption Status of an endpoint in the → table. For each endpoint, the table lists both system and custom drives that were encrypted.
The following table describes both the default and additional optional fields that you can view in the Disk Encryption Visibility table per endpoint. The fields are in alphabetical order.
The endpoint encryption status can be:
Unique ID assigned by Cortex XDR that identifies the endpoint.
Hostname of the endpoint.
The status of the endpoint. For more details, see Endpoints Table.
Last known IPv4 or IPv6 address of the endpoint.
Date and time of the last change in the agent’s status. For more details, see Endpoints Table.
The MAC address of the endpoint.
The platform running on the endpoint.
Name of the operating system version running on the endpoint.
Lists all the disks on the endpoint along with the status per volume, Decrypted or Encrypted. For Windows endpoints, Cortex XDR includes the encryption method.
You can also monitor the endpoint Encryption Status in your Endpoint Administration table.
Configure a Disk Encryption Profile
Under + New Profile or Import from File. Choose the Platform and select Disk Encryption. Click Next.→ → → , select
Fill-in the general information for the new profile.
Assign a name and an optional description to the profile.
Enable disk encryption.
To enable the Cortex XDR agent to apply disk encryption rules using the operating system disk encryption capabilities, Enable the Use disk encryption option.
Configure Encryption details.
Encrypt or decrypt the system drives.
Encrypt the entire disk or only the used disk space.
Inline with the operating system requirements, when the Cortex XDR agent attempts to enforce an encryption profile on an endpoint, the endpoint user is required to enter the login password. Limit the number of login attempts to one or three. Otherwise, if you do not force log in attempts, the user can continuously dismiss the operating system pop-up and the Cortex XDR agent will never encrypt the endpoint.
(Windows only) Specify the Encryption methods per operating system.
For each operating system (Windows 7, Windows 8-10, Windows 10 (1511), and above), select the encryption method from the corresponding list.
You must select the same encryption method configured by the Microsoft Windows Group Policy in your organization for the target endpoints. Otherwise, if you select a different encryption method than the one already applied through the Windows Group Policy, Cortex XDR displays errors.
(Mac only) Upload the FileVaultMaster certificate.
To enable the Cortex XDR agent to encrypt your endpoint, or to help users who forgot their password to decrypt the endpoint, you must upload to Cortex XDR the FileVaultMaster certificate / institutional recovery key (IRK). You must ensure the key is signed by a valid authority and upload a CER file only.
Save your profile.
When you’re done, Create your disk encryption profile.
Apply Disk Encryption Profile to Your Endpoints
After you define the required disk encryption profiles, configure Protection Policies and enforce them on your endpoints. Cortex XDR applies Protection policies on endpoints from top to bottom, as you’ve ordered them on the page. The first policy that matches the endpoint is applied. If no policies match, the default policy that enables all communication to and from the endpoint is applied.
Under +New policy or Import from File.→ → → , select
When importing a policy, select whether to enable the associated policy targets. Rules within the imported policy are managed as follows:
New rules are added to the top of the list.
Default rules override the default rule in the target tenant.
Rules without a defined target are disabled until the target is specified.
Configure settings for the disk encryption policy.
Assign a policy name and optional description.
The platform will automatically be assigned to Windows.
Assign the disk encryption profile you want to use in this rule.
Select the target endpoints on which to enforce the policy.
Use filters or manual endpoint selection to define the exact target endpoints of the policy rules. If exists, the Group Name is filtered according to the groups within your defined user scope.
Alternatively, you can associate the disk encryption profile with an existing policy. Right-click the policy and select Edit. Select the Disk Encryption profile and click Next. If needed, you can edit other settings in the rule, such as target endpoints and description. When you’re done, click Done.
Configure policy hierarchy.
Drag and drop the policies in the desired order of execution.
Save the policy hierarchy.
After the policy is saved and applied to the agents, Cortex XDR enforces the disk encryption policies on your environment.
Select one or more policies, right-click and select Export Policies. You can choose to include the associated Policy Targets, Global Exceptions, and endpoint groups.
