Chapter 1: Introduction

Chapter 1: IntroductionMicrosoft Active Directory Certificate Services (AD CS) provides the functionality for creating andinstalling a Certificate Authority (CA). The CA acts as a trusted third-party that certifies the identity ofclients to anyone who receives a digitally signed message. The CA may issue, revoke, and managedigital certificates.

The Online Responder is a Microsoft Windows Service that implements the Online Certificate StatusProtocol (OCSP) by decoding revocation status requests for specific certificates. The service providesup-to-date validation of certificates, and sends back a signed response containing the requestedcertificate status information. OCSP is used to provide real-time information about a certificate'sstatus.

The CA and OCSP use the Thales nShield Hardware Security Module (HSM) to protect their privatekeys.

Note: Throughout this guide, the term HSM refers to nShield® Solo™ modules (formerly known asnShield PCI and PCIe), nShield Connect™, and nShield Edge™ products.

They also use the HSM for important operations such as key generation, certificate signing, and CRLsigning. The Thales HSM can can be configured to protect the private keys and meet FederalInformation Processing Standards (FIPS) 140-2 level 2 or level 3.

Note: CA failover clustering is only supported with network attached HSMs (nShield Connect).

RequirementsBefore installing the software, we recommend that you familiarize yourself with the Microsoft AD CSand OCSP documentation and setup processes, and that you have the Thales nShield documentationavailable. We also recommend that you have an agreed organizational Certificate PracticesStatement and a Security Policy/Procedure in place covering administration of the PKI and HSM.

In particular, these documents should specify the following aspects of HSM administration:

l The number and quorum of Administrator Cards in the Administrator Card Set (ACS), and thepolicy for managing these cards

l Whether the application keys are protected by the module or an OCSl The number and quorum of Operator Cards in the OCS, and the policy for managing these cardsl Whether the security world should be compliant with FIPS 140-2 level 3l Key attributes such as the key size and time-outl Whether there is any need for auditing key usagel Whether to use the Thales Cryptographic Service Providers for Microsoft Cryptographic API: NextGeneration (CNG) or CryptoAPI (CAPI)

l Whether to initialize the nShield Security World as Recoverable; this is highly recommended.

Note: We recommend that you use CNG for full access to available features and better integrationwith Windows Server 2012 andWindows Server 2012 R2.

This guideThis guide describes how to configure AD CS and OCSP with the Thales nShield Hardware SecurityModule (HSM), and set up a root CA. We have tested the instructions, which provide astraightforward integration process. There may be other untested ways to achieve interoperability.This guide might not cover every step of the hardware and software setup process.

This guide assumes that you are familiar with the Thales HSM documentation and the setup process forAD CS and OCSP. For more information about installing the AD CS and OCSP, refer to the Microsoftdocumentation.

More informationl For more information about OS support, contact your Microsoft sales representative or ThalesSupport.

l For more information about contacting Thales, see Addresses at the end of this guide.l Additional documentation produced to support your Thales product is in the document directory ofthe CD-ROM or DVD-ROM for that product.

l For more information about HSM administration, refer to the User Guide for the HSM.


Chapter 2: Procedures

Chapter 2: ProceduresInstalling the HSMInstall the HSM using the instructions in the Hardware Installation Guide for the HSM. We recommendthat you install the HSM before configuring the Security World Software, and before installing andconfiguring AD CS and OCSP.

If you already have an HSM installed and a security world configured, proceed to Installing andconfiguring AD CS on page 7.

Installing the software and creating or sharing the security worldTo install the Security World Software and create the security world:

1. Install the latest version of the Security World Software as described in the User Guide for theHSM.Note: We recommend that you always uninstall any existing Security World Software before

installing the new Security World Software.2. Initialize a security world as described in the User Guide for the HSM.

Note: You can also use the CSP Install Wizard or the CNG Configuration Wizard to create aSecurity World for nShield Solo and nShield Edge HSMs. For nShield Connect, werecommend that you use the front panel user interface to create the Security World.

3. Register the Cryptographic Service Providers that you intend to use.Note: For CAPI on 64-bit Windows, both 32-bit and 64-bit CSP Install Wizards are available. If

you intend to use the CAPI CSPs from both 32-bit and 64-bit applications, or if you areunsure, run both wizards. The CNG Configuration Wizard registers the CNG Providersfor use by both 32-bit and 64-bit applications where relevant. For detailed information onregistering the CAPI CSPs or CNG Providers, refer to the User Guide for the HSM.

4. If you are installing OCSP on a different server to the CA, install the Security World Software onboth servers (as described in the User Guide for the HSMs) and share the Security World bycopying the %NFAST_KMDATA%\local directory from the CA server to the OCSP server. See theUser Guide for more information.Note: You can also have the security world files in a shared network location which can be

accessed by both the CA and OCSP server.

Setting up key use counting

Setting up key use counting

Key use counter overviewSetting up key use counting is optional. If you require key use counting, follow the proceduresdescribed in this section. The procedures described in this section do not apply to most setups.

Note: If you do not follow the procedures described in this section, key use counting is not installed.You cannot add key use counting to a key retrospectively.

The key use counter audits usage of the CA signing key. It maintains a count of how many times thekey has been used. The key use counter should only be used with a root CA that has a low volume ofsignings where the count can be logged immediately before servicing a signature request and afterthe signature request has been serviced. This ensures that any illicit use of the CA is revealed throughdiscrepancies in the counter log.

Note: Note the following information about the key use counter:

l The counter is in the NVRAM of the HSM. To access the key count value in NVRAM, users mustpresent the ACS to the HSM.

l The counter is a 64-bit integer counter associated with a single private key.l The counter is started at zero.l If the maximum count is reached, the counter restarts at zero.l The counter can exist only on one HSM. If more than one HSM is attached to the server, you mustchoose which HSM stores the counter.

l If the module firmware is upgraded, the counter value is lost.

l The key counter can only be set at HSM initialization, it cannot be activated after deployment.

Installing Certificate Services with key use countingTo install Certificate Services with key use counting:

1. If it is not already on your system installation, create the file %SystemRoot%\capolicy.inf (where%SystemRoot% is the system environment variable for the Windows installation folder, by defaultC:\WINDOWS\capolicy.inf) with the following content:

[Version]

Signature="$Windows NT$"

[certsrv_server]

EnableKeyCounting=True

Note: You must create the capolicy.inf file before Certificate Services is installed.2. Install the CA using the HSM KSP.3. Enable auditing for the CA service by running the command:

>certutil -setreg ca\auditfilter 1

4. Right-click the CA and click Properties.



5. Click the Auditing tab and check the box for Start and Stop Active Directory CertificateServices.

6. Select Start > Administrative Tools > Local Security Policy.7. Go to Local Policy, expand it and select Audit Policy.8. In the right pane, double-click Audit Object Access and select Success and Failure.9. Click Apply and then OK, then close the window.10. Update the local security policies by opening a command prompt and running the command:

>gpupdate.exe /force

11. Restart the CA service to pick up the changes, by running the commands:

>net stop certsvc

>net start certsvc

12. Run Eventvwr.exe.13. Select Windows Logs > Security.14. Filter for event ID 4881 (CA startup event) or event ID 4880.15. Verify the CA startup event shows the PrivateKeyUsageCount property with a corresponding

value. Make a note of this value.16. Restart the Certificate Server, by running the commands:

>net stop certsvc

>net start certsvc

17. Verify that the event viewer contains a new CA startup event (event ID 4881).18. Make a note of the PrivateKeyUsageCount property value.

CA Backup, migrate and restoreThe most common procedure related to backup, migrate and restore for the CA and HSM is to use theoptions:

l Select a certificate and use its associated private key.l Select an existing private key.

This procedure describes backing up the CA / HSM data on an existing server and then restoring theCA / HSM data onto a new server. Thales have successfully tested this procedure in the followingconfigurations:

l Windows Server 2008 SP2 Enterprise 64-bit (CNG) to Windows Server 2012 (CNG)l Windows Server 2008 R2 SP1 Enterprise 64-bit (CNG) to Windows Server 2012 (CNG)l Windows Server 2008 R2 SP1 Enterprise 64-bit (CNG) to Windows Server 2012 R2 (CNG)l Windows Server 2012 (CNG) to Windows Server 2012 R2 (CNG)


Backing up, migrating and restoring CA using an existing certificate and its associated private key

Note: If your existing CA is using a custom CAPolicy.inf file, you should copy the file to the newplanned CA server. The CAPolicy.inf file is located in the %SystemRoot% directory, which isusually C:\Windows.

local C drive:



[Version]

Signature = "$Windows NT$"

[NewRequest]

Suject = "CN=TEST-CA"

HashAlgorithm = SHA512

KeyAlgorithm = RSA

KeyLength = 2048

ProviderName = "nCipher Security World Key Storage Provider"

KeyUsage = 0xf0

MachineKeySet = True

RequestType = PKCS10

[EnhancedKeyUsageExtension]

OID = 1.3.6.1.5.5.7.3.1

[Extensions]

1.3.6.1.5.5.7.48.1.5 = Empty

In the rsa.inf file replace the subject with your CA common name.2. Go to your local directory and find the file rsa.inf.3. Check that rsa.inf contains the following messages:

Leaf certificate revocation check passed

CertUtil: -verify command completed successfully.

4. From the command prompt navigate to your local C drive and add:

>certreq —new rsa.inf rsa.req

5. Check that rsa.req is listed in the directory.6. In the command line run the command:

Problem Cause Resolution

Online Responder reportsBad Signing Certificateon Array Controller.

This error occurs whenthe CA certificate is staleor cannot be located bythe Online Responderclient.

Ensure that the steps above have been correctlycarried out. Also, ensure that the CA is correctlyconfigured and that a valid CA certificate existsfor OCSP Signing.

Using

certutil —url

<certnamehere.cer>

and selecting Certs (fromAIA) shows an entry inthe list called AIA withFailed next to it.

This error occurs whenCertificate AuthorityWeb Enrolment is notinstalled on the CA.

Install Certificate Authority Web Enrolment onthe CA machine. Go to Server Manager.Expand the Roles section (in the left-handsection) and click Active Directory CertificateServices. In the bottom right-hand section, clickAdd Role Services and select CertificateAuthority Web Enrolment.

Using the certreq —new

<.req file here>

command returns anInvalid Provider Specifiederror.

This error occurs whenthe CSPs are not installedand set up on the clientmachine or not set upcorrectly.

Ensure that the Thales CAPI CSP and ThalesCNG CSP providers are correctly installed andset. (Do this by running the CSP Install Wizardand CNG Configuration Wizard under nCipherin the Start menu).

When using the CAPI orCNG wizard to access aprivate key protected byan OCS with password,you are prompted multipletimes to enter thepassword.

This error is due to aproblem in WindowsServer 2012.

To prevent this from happening, download andinstall the hotfix available at the followinglocation:http://support.microsoft.com/kb/2740017/EN-US
