Introduction
Read this guide if …
Read this guide if you need to configure or manage:
-
An Entrust Hardware Security Module (HSM).
-
An associated Security World. nShield hardware security modules use the Security World paradigm to provide a secure environment for all your HSM and key management operations.
All nShield HSMs support standard cryptography frameworks and integrate with many standards based products.
This guide assumes that:
-
You are familiar with the basic concepts of cryptography and Public Key Infrastructure (PKI)
-
You have read the Installation Guide.
-
You have installed your nShield HSM.
| Throughout this guide, the term Installation Guide refers to the particular Installation Guide for your product. |
Terminology
The nShield Solo and nShield Solo XC are also referred to as the hardware security module or the nShield HSM.
This guide refers to other nShield HSMs by type:
| nShield HSMs | nShield HSM type |
|---|---|
Connect, Connect +, Connect XC, 5c |
Network-attached HSMs |
Solo, Solo +, Solo XC, 5s |
PCIe HSMs |
Edge |
USB-attached HSMs |
Model numbers
Model numbering conventions are used to distinguish different nShield hardware security devices.
| Model number | Used for |
|---|---|
nC3nnnE-nnn, nC4nnnE-nnn |
nShield Solo PCIe |
nC30n5E-nnn, nC40n5E-nnn |
nShield Solo XC PCIe |
Security World Software
The hardserver software controls communication between applications and Entrust nShield product line HSMs, which may be installed locally or remotely. It runs as a daemon on the host computer.
The Security World for nShield is a collection of programs and utilities, including the hardserver, supplied by Entrust to install and maintain your nShield security system.
The nShield HSM is supplied with the latest version of the HSM firmware installed. For more information about:
-
Upgrading the firmware, see Upgrading firmware.
-
Installing and configuring the software on each client computer, see the Installation Guide and Client Software and module configuration.
-
The supplied utilities, see Supplied utilities.
-
Maintenance of your nShield hardware, see Maintenance of nShield Hardware.
Software architecture
The software, firmware, and utilities have version numbers and there is also a version number for the World which refers to the World data that is stored in encrypted form on the client computer, typically in the NFAST_KMDATA directory or on the RFS.
This data includes information concerning the World itself and also concerning each key that was created within that World.
The World version created is determined by the version numbers of the software and firmware used when it was first created, see Creating and managing a Security World.
The latest World version is version 3.
You can query the version of the World loaded on your system by using the command kmfile-dump.
Default directories
The default locations for Security World Software and program data directories on English-language systems are summarized in the following table:
| Directory name | Default path |
|---|---|
nShield Installation |
|
Key Management Data |
|
Dynamic Feature Certificates |
|
Static Feature Certificates |
|
Log Files |
|
User Log Files |
|
Remote Static Feature Certificates |
|
|
Remote Dynamic Feature Certificates |
|
| Dynamic feature certificates must be stored in the directory stated above. The directory shown for static feature certificates is an example location. You can store those certificates in any directory and provide the appropriate path when using the Feature Enable Tool. However, you must not store static feature certificates in the dynamic features certificates directory. |
The instructions in this guide refer to the locations of the software installation and program data directories by their names (for example, Key Management Data) or
absolute paths (for example, /opt/nfast/kmdata).
If the software has been installed into a non-default location, you
must create a symbolic link from /opt/nfast/ to the directory where the software is actually installed. For more information about creating symbolic links, see your operating system’s documentation.
Utility help options
Unless noted, all the executable utilities provided in the bin subdirectory of your nShield installation have the following standard help options:
-
-h|--helpdisplays help for the utility -
-v|--versiondisplays the version number of the utility -
-u|--usagedisplays a brief usage summary for the utility.
Setting the PATH for nShield utilities
It is recommended that the PATH environment variable be changed to include
opt/nfast/bin.
This is the directory in the nShield installation that contains the nShield command-line utilities and some DLLs.
This will allow all the nShield command-line utilities to be run without the need to type the full path, for example running enquiry instead of
opt/nfast/bin/enquiry>.
opt/nfast/bin
must be set in the PATH in order to use the OpenSSL module in the Python that is bundled with nShield.
The Python bundled with nShield is located in a separate directory,
opt/nfast/python/bin.
If using the nShield Python, you may additionally want to add this directory to the PATH environment variable so that you can run the nShield python as just the python command.
You may not want to do this if you are also using other Python installations on the same machine.
Further information
This guide forms one part of the information and support provided by Entrust.
If you have installed the Java Developer component, the Java Generic Stub classes, nCipherKM JCA/JCE provider classes, and Java Key Management classes are supplied with HTML documentation in standard Javadoc format, which is installed in the appropriate
nfast/java
directory when you install these classes.
Security advisories
If Entrust becomes aware of a security issue affecting nShield HSMs, Entrust will publish a security advisory to customers. The security advisory will describe the issue and provide recommended actions. In some circumstances the advisory may recommend you upgrade the nShield firmware and or image file. In this situation you will need to re-present a quorum of administrator smart cards to the HSM to reload a Security World. As such, deployment and maintenance of your HSMs should consider the procedures and actions required to upgrade devices in the field.
| The Remote Administration feature supports remote firmware upgrade of nShield HSMs, and remote ACS card presentation. |
We recommend that you monitor the Announcements & Security Notices section on Entrust nShield, https://nshieldsupport.entrust.com, where any announcement of nShield Security Advisories will be made.
