Issue/Introduction

The Appliance Birth Registration Certificate Authority (ABRCA) root CA certificate is the ultimate root of trust for all appliance certificates that Symantec products use. Symantec has created a new ABRCA root CA certificate to replace the one expiring in December 2021. Before the older root CA certificate expires, ensure that the new root CA certificate is installed on your appliances. The new certificate will have an expiration date of Dec 31 00:04:16 2037 GMT.

When the root CA certificate expires, some features that use the ABRCA root CA certificate for authentication will fail. See the end of this article for additional details. 

 

Resolution

IMPORTANT: The information in this article has changed. After additional testing, it was discovered that manually updating the trust package and appliance certificate was not sufficient for all products. Management Center requires a software upgrade to do proper certificate validation during subscription downloads.

If you are running Management Center 3.x, you must do the following:

  • Upgrade Management Center to MC 3.2.1.1 (or later). MC 3.2.1.1 (and later) includes the new ABRCA root CA certificate.
  • Verify that the trust package and appliance certificate were updated properly.

If you are running Management Center 2.4, you must do the following:

  • Upgrade Management Center to MC 2.4.3.1 (or later). MC 2.4.3.1 (and later) includes the new ABRCA root CA certificate.
  • Manually update the appliance certificate. The appliance certificate does not automatically update itself in MC 2.4.3.1. You can update the appliance certificate before, or after, upgrading to MC 2.4.3.1.
  • Verify that the trust package and appliance certificate were updated properly.

The continued operation of your Management Center appliances requires that you complete the following actions in a timely manner. To ensure the uninterrupted operation of your appliances, request a new appliance certificate and perform a software update by August 31, 2021 to allow for adequate testing and troubleshooting before the certificate expires.

Update the Appliance Certificate 

Refer to the appropriate instructions to update the appliance certificate:

 

Update the Hardware Appliance Certificate

Note: Ensure that the appliance can access abrca.bluecoat.com for appliance certificate downloads.

To update the appliance certificate on a hardware appliance, log into the Management Center CLI and enter the following command:

# request-appliance-certificate
ok

Update the Virtual Appliance Certificate

Note: Ensure that the appliance can access abrca.bluecoat.com for appliance certificate downloads.

To update the appliance certificate on a virtual appliance (VA), log into the Management Center CLI and enter the following command:

(config)# licensing load username <username> password <password>
ok

where <username> and <password> are your Broadcom licensing portal credentials.

If the appliance is in a closed environment, see the next section.

Update the Virtual Appliance Certificate in a Closed Environment

In a closed environment, you must manually download the license file and host it on a file server that the appliance can access, or install it inline. 

To update the virtual appliance certificate in a closed environment:

  1. Generate the license key from the Broadcom Support Portal following the instructions for Symantec products in KB145804. Specify a passphrase before generating the license key to ensure that the license includes appliance certificate information.
  2. Download the license key and put it on a file server the appliance can access.
  3. Install the license via the CLI using one of the following methods:

Install from file server


(config)# licensing load url <url> passphrase <passphrase>

where <url> is the location of the file and <passphrase> is the passphrase you specified on the Support Portal.

 

Install inline


Open the license file and copy its contents. Paste the contents using the following command.

(config)# licensing inline license-key passphrase <passphrase>

where <passphrase> is the passphrase you specified on the Support Portal.

(config-ssl)# view keyring bluecoat-appliance

Consequences of an Expired Appliance Certificate

If the appliance certificate expires, the following failures might occur:

  • Appliance certificate update
  • Licensing updates
  • Subscription updates
  • Diagnostics and Heartbeat uploads
  • License validation services on virtual appliances:
    • Failures for more than 7 days will disable the license
  • Subscription download of WAF rules

Other issues, yet to be identified, might also occur. 

Recovery: What to Do If You Fail to Update Before the Certificate Expires

If you fail to update your Management Center appliances before the root CA expires in December 2021, your appliances might experience failures as described in "Consequences of an Expired Appliance Certificate." The steps to renew the certificate are identical, whether you renew the root CA before, or after, the certificate expires. To renew the certificate, follow the steps in this article to upgrade to a new build that contains the updated trust package.
