NATIONAL CYBERSECURITY CENTER OF EXCELLENCE

The National Cybersecurity Center of Excellence (NCCoE), a part of the National Institute of Standards and Technology (NIST), is a collaborative hub where industry organizations, government agencies, and academic institutions work together to address businesses’ most pressing cybersecurity issues. This public-private partnership enables the creation of practical cybersecurity solutions for specific industries, as well as for broad, cross-sector technology challenges. Through consortia under Cooperative Research and Development Agreements (CRADAs), including technology partners—from Fortune 50 market leaders to smaller companies specializing in IT security—the NCCoE applies standards and best practices to develop modular, easily adaptable example cybersecurity solutions using commercially available technology. The NCCoE documents these example solutions in the NIST Special Publication 1800 series, which maps capabilities to the NIST Cyber Security Framework and details the steps needed for another entity to recreate the example solution. The NCCoE was established in 2012 by NIST in partnership with the State of Maryland and Montgomery County, Md.

NIST CYBERSECURITY PRACTICE GUIDES

NIST Cybersecurity Practice Guides (Special Publication Series 1800) target specific cybersecurity challenges in the public and private sectors. They are practical, user-friendly guides that facilitate the adoption of standards-based approaches to cybersecurity. They show members of the information security community how to implement example solutions that help them align more easily with relevant standards and best practices and provide users with the materials lists, configuration files, and other information they need to implement a similar approach.

The documents in this series describe example implementations of cybersecurity practices that businesses and other organizations may voluntarily adopt. These documents do not describe regulations or mandatory practices, nor do they carry statutory authority.

ABSTRACT

Federal Information Processing Standards (FIPS) Publication 201-2, “Personal Identity Verification (PIV) of Federal Employees and Contractors,” establishes a standard for a PIV system based on secure and reliable forms of identity credentials issued by the federal government to its employees and contractors. These credentials are intended to authenticate individuals who require access to federally controlled facilities, information systems, and applications. In 2005, when FIPS 201 was published, logical access was geared toward traditional computing devices (i.e., desktop and laptop computers) where the PIV card provides common multifactor authentication mechanisms through integrated smart card readers across the federal government. With the emergence of computing devices such as tablets, convertible computers, and in particular mobile devices, the use of PIV cards has proved challenging. Mobile devices lack the integrated smart card readers found in laptop and desktop computers and require separate card readers attached to devices to provide authentication services. To extend the value of PIV systems into mobile devices that do not have PIV Card readers, NIST developed technical guidelines on the implementation and lifecycle of identity credentials that are issued by federal departments and agencies to individuals who possess and prove control over a valid PIV card. These NIST guidelines, published in 2014, describe Derived PIV Credentials (DPCs) which leverage identity proofing and vetting results of current and valid PIV credentials.

To demonstrate the DPCs guidelines, the National Cybersecurity Center of Excellence (NCCoE) at NIST built a security architecture using commercial technology to manage the lifecycle of DPCs demonstrating the process that enables a PIV Card holder to establish DPCs in a mobile device which then can be used to allow the PIV Card holder to access websites that require PIV authentication.

This project resulted in a freely available NIST Cybersecurity Practice Guide which demonstrates how an organization can continue to provide two-factor authentication for users with a mobile device that leverages the strengths of the PIV standard. Although this project is primarily aimed at the Federal sector’s needs, it is also relevant to mobile device users with smart card based credentials in the private sector.

1. Introduction

The following guides show IT professionals and security engineers how we implemented this example solution. We cover all of the products employed in this reference design. We do not recreate the product manufacturers’ documentation, which is presumed to be widely available. Rather, these guides show how we incorporated the products together in our environment.

Note: These are not comprehensive tutorials. There are many possible service and security configurations for these products that are out of scope for this reference design.

1.1. Practice Guide Structure

This NIST Cybersecurity Practice Guide demonstrates a standards-based reference design and provides users with the information they need to replicate Derived Personal Identity Verification (PIV) Credential (DPC) lifecycle solution. This reference design is modular and can be deployed in whole or in parts.

This guide contains three volumes:

  • NIST SP 1800-12a: Executive Summary
  • NIST SP 1800-12b: Approach, Architecture, and Security Characteristics – what we built and why
  • NIST SP 1800-12c: How-To Guides – instructions for building the example solution (you are here)

Depending on your role in your organization, you might use this guide in different ways:

Business decision makers, including chief security and technology officers will be interested in the Executive Summary (NIST SP 1800-12a), which describes the:

  • challenges enterprises face in issuing strong, two-factor credentials to mobile devices
  • example solution built at the NCCoE
  • benefits of adopting the example solution

Technology or security program managers who are concerned with how to identify, understand, assess, and mitigate risk will be interested in this part of the guide, NIST SP 1800-12b, which describes what we did and why. The following sections will be of particular interest:

  • Section 3.4.3, Risk, provides a description of the risk analysis we performed
  • Section 3.4.4, Security Control Map, maps the security characteristics of this example solution to cybersecurity standards and best practices

You might share the Executive Summary, NIST SP 1800-12a, with your leadership team members to help them understand the importance of adopting a standards-based Derived PIV Credential lifecycle solution.

IT professionals who want to implement an approach like this will find the whole practice guide useful. You can use the How-To portion of the guide, NIST SP 1800-12c, to replicate all or parts of the build created in our lab. The How-To guide provides specific product installation, configuration, and integration instructions for implementing the example solution. We do not recreate the product manufacturers’ documentation, which is generally widely available. Rather, we show how we incorporated the products together in our environment to create an example solution.

This guide assumes that IT professionals have experience implementing security products within the enterprise. While we have used a suite of commercial products to address this challenge, this guide does not endorse these particular products. Your organization can adopt this solution or one that adheres to these guidelines in whole, or you can use this guide as a starting point for tailoring and implementing parts of a Derived PIV Credential lifecycle solution. Your organization’s security experts should identify the products that will best integrate with your existing tools and IT system infrastructure. We hope you will seek products that are congruent with applicable standards and best practices. Volume B, Section 4.2, Technologies, lists the products we used and maps them to the cybersecurity controls provided by this reference solution.

A NIST Cybersecurity Practice Guide does not describe “the” solution, but a possible solution. This is a draft guide. We seek feedback on its contents and welcome your input. Comments, suggestions, and success stories will improve subsequent versions of this guide. Please contribute your thoughts to piv-nccoe@nist.gov.

1.2. Build Overview

Unlike desktop computers and laptops that have built-in readers to facilitate the use of PIV Cards, mobile devices pose usability and portability issues because of the lack of a smart card reader.

NIST sought to address this issue with the introduction of the general concept of Derived PIV Credentials in SP 800-63-2, which leverages identity proofing and vetting results of current and valid credentials. Published in 2014, SP 800-157, Guidelines for Derived Personal Identity Verification (PIV) Credentials defined requirements for initial issuance and maintenance of Derived PIV Credentials. NIST’s Applied Cybersecurity Division then created a NCCoE project to provide an example solution for federal agencies and private entities that follows the requirements in SP 800-157.

In the NCCoE lab, the team built an environment that resembles an enterprise network using commonplace components such as identity repositories, supporting certificate authorities (CA), and web servers. In addition, products and capabilities were identified that, when linked together, provide an example solution that demonstrate lifecycle functions outlined in SP 800-157. Figure 1-1 depicts the final lab environment.

2. Product Installation Guides

This section of the practice guide contains detailed instructions for installing and configuring of key products used for the depicted architecture illustrated below, as well as demonstration of the DPC lifecycle management activities of initial issuance and termination.

In our lab environment, the example solution was logically separated by a Virtual Local Area Network (VLAN) wherein each VLAN represented a mock enterprise environment. The network topology consists of an edge router connected to a Demilitarized Zone (DMZ). An internal firewall separates the DMZ from internal systems that support the enterprise. All routers and firewalls used in the example solution were virtual pfSense appliances.

As a basis, the enterprise network had an instance of Active Directory (AD) to serve as a repository for identities to support DPC vendors.

Figure 2‑1 Build 1 Architecture

2.1. Entrust Datacard IdentityGuard (IDG)

Entrust Datacard contributed test instances of their managed Public Key Infrastructure (PKI) service and IdentityGuard products, the latter of which directly integrates with MobileIron to support the use of Derived PIV Credentials with MobileIron Mobile@Work apps. Contact Entrust Datacard (https://www.entrust.com/contact/) to establish service instances in support of a Derived PIV Credentials with MobileIron (https://www.mobileiron.com/).

2.1.1. Identity Management Profiles

To configure services and issue certificates for Derived PIV Credentials that will work with your organization’s user identity profiles, Entrust Datacard will need information on how identities are structured and which users will use PKI services. For this lab instance, Entrust Datacard issued PIV Authentication, Digital Signature, and Encryption certificates for PIV Cards and Derived PIV Credentials for two test identities, as represented below.

    3. The LDAP Test dialog indicates the query was successful:

      Results of the LDAP test indicating the user ID was found.

2.2.3.2. Create a DPC Users Label

MobileIron uses labels to link policies and device configurations with users and mobile devices. Creating a unique label for DPC users allows mobile device administrators to apply controls applicable to mobile devices provisioned with a derived credential specifically to those devices. We recommend applying DPC-specific policies and configurations to this label, in addition to any others appropriate to your organization’s mobile device security policy.

  1. In the MobileIron Core Admin Portal, navigate to Devices & Users > Devices.

  2. Select Advanced Search (far right).

    Shows all pending and active device registrations in MobileIron Core.

  3. In the Advanced Search pane:

    1. In the blank rule:
      1. In the Field drop-down menu, select User > LDAP > Groups > Name.
      2. In the Value drop-down menu, select the Active Directory group created to support DPC-specific MobileIron policies (named DPC User in this example).
    2. Select the plus sign icon to add a blank rule.
    3. In the newly created blank rule:
      1. In the Field drop-down menu, select Common > Platform.
      2. In the Value drop-down menu, select iOS.
    4. Optionally, select Search to view matching devices.
    5. Select Save to Label.

    1. In the Save to Label dialog:
      1. In the Name field, enter a descriptive name for this label (DPC Users in this example).
      2. In the Description field, provide additional information to convey the purpose of this label.
      3. Click Save.

    Shows the provisioning of a name and description for a new label used to apply MobileIron policies and configurations to users of Derived PIV Credentials.

  4. Navigate to Devices & Users > Labels to confirm the label was successfully created. It can be applied to Derived PIV Credential-specific MobileIron policies and configurations in future steps.

    Shows all existing labels in MobileIron, confirming creation of the DPC Users label.

2.2.3.3. Implement MobileIron Guidance

The following provides the sections from the MobileIron Derived Credentials with Entrust Guide that were used in configuring this instance of MobileIron Derived PIV Credentials. Sections for which there may be configuration items tailored to a given instance (e.g., local system hostnames), this configuration is provided only as a reference. We noted any sections in which the steps performed to configure our systems varies from those in the MobileIron Derived Credentials with Entrust Guide.

Complete these sections in Chapter 2 of the MobileIron Derived Credentials with Entrust Guide:

  1. Before beginning:

    1. Configuring certificate authentication to the user portal.

      Note: The root CA certificate or trust chain file can be obtained from Entrust Datacard.

    2. Configuring the Entrust IdentityGuard Self-Service Module (SSM) Module Universal Resource Locator (URL).

      Note: The URL will be specific to your organization’s instance of the IDG service and can be obtained from Entrust Datacard.

  2. Configuring PIN-based registration.

  3. Configuring user portal roles.

  4. Adding the PIV-D Entrust app to the App Catalog.

    1. Adding Web@Work for iOS.

      3. Continue with Step 7.

    MobileIron Self-Service Portal attempting to redirect the user to the Entrust Dataguard IDG Self-Service Portal generates a prompt to select a certificate for authentication.

  6. To request a Derived PIV Credential in a new session:

    1. Using a web browser, visit the Entrust IDG Self-Service Portal URL provided by an administrator.

    2. In the Entrust IDG Self-Service portal, under Smart Credential Log In, click Log In.

      Note: The portal used in our test environment is branded as a fictitious company, AnyBank Self-Service.

    User is presented with authentication options.

    1. In the Select a certificate dialog:

      1. Select your PIV Authentication certificate from the list of available certificates. See Step 4 of Section 2.3.1.1 for additional steps to identify this certificate, as necessary.
      2. Click OK.

    The user is prompted to select the PIV Authentication certificate from the list of available certificates.

    1. In the authentication dialog:

      1. In the PIN field, enter the password to activate your PIV Card.
      2. Click OK.

    User enters the password to unlock the private key for the PIV Authentication certificate selected in the previous step.

  7. On the Self-Administration Actions page, follow the I’d like to enroll for a derived mobile smart credential link (displayed below as the last item; this may vary based on which self-administration actions your Entrust IDG administrator enabled).

    Service displays a list of actions the user can perform in the Entrust IDG Self-Service Portal.

  8. On the Smart Credential enabled Application page, select Option 2: I’ve successfully downloaded and installed the Smart Credential enabled application.

  9. On the Derived Mobile Smart Credential page:

    1. In the Identity Name field, enter your LDAP or MobileIron user ID.
    2. Click OK.

    User enters the identity name for the derived credential to be issued.

  10. The Derived Mobile Smart Credential QR Code Activation page displays information used in future steps; keep this page displayed. The workflow resumes using the MobileIron PIV-D Entrust app open on the target mobile device.

    Note: Steps 11-13 must be completed using the target mobile device within approximately three minutes or Steps 7-10 must be repeated to generate new activation codes.

Figure 2‑3 Derived Mobile Smart Credential QR Code Activation Page

The Entrust IDG Self-Service Portal displays a QR code and PIN used in future issuance steps performed using the target mobile device. Leave this page displayed.
  1. In the PIV-D Entrust app running on the target mobile device, tap Activate New Credential.

  3. On the Activate Credential screen:

    1. Enter the password below the QR code displayed on the Derived Mobile Smart Credential QR Code Activation page (displayed by the same device used to perform Steps 4-10) as represented in Figure 2-3.
    2. Tap Activate.

    User enters the activation code displayed on the Entrust IDG Self-Service Portal.

  4. If issuance was successful, the PIV-D Entrust app should automatically launch MobileIron. Go to Mobile@Work > Settings > Entrust Credential to view its details.

    The MobileIron app displays details on the provisioned DPC.

2.3.2. DPC Maintenance

Changes to a DPC Subscriber’s PIV Card that result in a re-key or reissuance (e.g., official name change) require the subscriber to repeat the initial issuance workflow as described in the previous section. The issued DPC will replace any existing DPC in the MobileIron Apps@Work container.

2.3.3. DPC Termination

Termination of a DPC can be initiated from the MobileIron Admin Console. Upon completion of this workflow, the DPC stored in the MobileIron Apps@Work container will be cryptographically wiped (destroyed). These steps are performed by a MobileIron Core administrator.

  1. In the MobileIron Admin Console, navigate to Devices & Users > Devices.

    Devices tab lists all of the managed mobile devices.

  2. Select the checkbox in the row identifying the mobile device to be retired.

    Selection of a specific mobile device in the Devices tab.

  3. Select Actions > Retire.

    Administrator selects Actions > Retire.

  4. In the Retire dialog that appears:

    1. In the Note textbox, enter the reason(s) the device is being retired from MobileIron.
    2. Select Retire.

    Administrator enters a reason the mobile device is to be retired from management by MobileIron.

  5. The Devices tab no longer displays the retired mobile device in the list of the devices.

The MobileIron PIV-D Entrust app now no longer reflects management by MobileIron. As a result, the Derived PIV Credential has been cryptographically wiped (destroyed) and its recovery is computationally infeasible.
