HSM Capabilities and Policies

The HSM can be configured to suit the cryptographic needs of your organization. Configurable functions are governed by the following settings:

>HSM Capabilities are features of HSM functionality, set at manufacture based on the HSM model you selected at time of purchase. You can add new capabilities to the HSM by purchasing and applying capability licenses from Thales Group (see Upgrading HSM Capabilities). Some capabilities have corresponding modifiable HSM policies.

>HSM Policies are configurable settings that allow the HSM Security Officer to modify the function of their corresponding capabilities. Some policies affect HSM-wide functionality, and others allow further customization of individual partitions by the Partition Security Officer.

The table below describes all SafeNet Luna PCIe HSM capabilities, their corresponding policies, and the results of changing their settings. This section contains the following procedures:

>Setting HSM Policies Manually

>Setting HSM Policies Using a Template

To zeroize the HSM and revert policies to their default values, see Resetting the SafeNet Luna PCIe HSM to Factory Condition.

To zeroize the HSM and keep the existing policy settings, use lunacm:> hsm zeroize
