Deploying patches for password-protected BIOS

This feature is available on the Enterprise edition of Patch Manager Plus for builds 11.2.2338.1 and above.

Configuring password protection for the BIOS in the systems of the network is often the first step of defense in preventing unauthorized access to the system. In addition, this also forbids malicious/unauthorized users from making changes to the system's hardware and software configurations.

However, this added security layer can prove to be a hassle, especially when it comes to deploying BIOS updates across the endpoints in your organization's network. Since these updates require authentication via credentials before installation, this would mean relying on the end-users to input the credentials for a successful installation, thus leading to either productivity breaks or a lesser chance of successful installations.

Patching password-protected BIOS with Patch Manager Plus

The Password-protected BIOS Patching functionality lets you deploy updates for the protected BIOS, without having to rely on the end-user for password authentication.

By leveraging this functionality, admins can store the pre-configured BIOS passwords of the end-user systems on the Patch Manager Plus server. This ensures that the BIOS updates are deployed and the passwords are automatically fetched and installed from the server storage, for a seamless installation.

How to deploy patches to systems with password-protected BIOS?

While this feature is enabled by default in the server, admins are required to add and map the credentials before deploying the patches for a successful installation. Here are the steps:

Adding and mapping BIOS credentials

  1. On the product console, navigate to Admin > BIOS Credential Settings (under Patch Settings)
  2. Click on Add BIOS Credential
  3. Enter the Credential Name, Description (optional) and the Password.
  4. You can map the credentials to any of the following:
    • All Computers: Maps the BIOS credentials to all of the computers in the network.
    • Vendor(s): Maps the credentials to specific vendor(s) (Dell, HP, and Lenovo).
    • Custom Group(s): Maps the credentials to one or more Custom Groups as required.
  5. Once done, click on Save to add and map the credentials to the required systems.

Deploying BIOS updates

Once the credentials have been mapped, the BIOS updates can be deployed to the systems either via a Manual Deployment or via an Automate Patch Deployment task.

Review the BIOS-mapping status of the systems

Admins can review and monitor the BIOS-mapping status of all the systems in the network from a single dashboard. To review the status of these systems on the console, navigate to Systems > BIOS Mapping Status (under Attention Required). The system status has been broken down into three types:

  1. Protected & Mapped: List of systems with password-protected BIOS, whose credentials have been added to the server. Installing BIOS updates for these systems would not require any authentication from the end-users.
  2. Protected & Unmapped: List of systems with password-protected BIOS. These systems would require user authentication while installing BIOS updates.
  3. Unprotected: List of systems in the network without password-protected BIOS.
