One Identity Safeguard for Privileged Sessions 6.0.2 - YubiKey Multi-Factor Authentication - Overview



This tutorial describes the deprecated version of the plugin.

To upgrade your deprecated plugin for One Identity Safeguard for Privileged Sessions 6.0, see Upgrading plugins for One Identity Safeguard for Privileged Sessions version 6.0.

This document describes how you can use the services of Yubico (YubiKey) to authenticate the sessions of your privileged users with One Identity Safeguard for Privileged Sessions (SPS).

One Identity Safeguard for Privileged Sessions:

One Identity Safeguard for Privileged Sessions (SPS) controls privileged access to remote IT systems, records activities in searchable, movie-like audit trails, and prevents malicious actions. SPS is a quickly deployable enterprise device, completely independent from clients and servers — integrating seamlessly into existing networks. It captures the activity data necessary for user profiling and enables full user session drill down for forensic investigations.

SPS acts as a central authentication gateway, enforcing strong authentication before users access sensitive IT assets. SPS can integrate with remote user directories to resolve the group memberships of users who access nonpublic information. Credentials for accessing information systems can be retrieved transparently from SPS's local credential store or a third-party password management system. This method protects the confidentiality of passwords as users can never access them. When used together with YubiKey (or another multi-factor authentication provider), SPS directs all connections to the authentication tool, and upon successful authentication, it permits the user to access the information system.

Integrating YubiKey with SPS:

SPS can interact with your YubiKey account and can automatically request strong multi-factor authentication for your privileged users who are accessing the servers and services protected by PSM. When used together with YubiKey, SPS directs all connections to the YubiKey tool, and upon successful authentication, it permits the user to access the information system.

The integration adds an additional security layer to the gateway authentication performed on SPS. YubiKey 4, YubiKey 4 Nano, and YubiKey NEO devices are pre-configured with the Yubico one-time password (OTP) (all other YubiKeys, except for the FIDO U2F Security Key by Yubico, also support Yubico OTP). The OTP will be used for authentication to the One Identity platform. This way, the device turns into a two-factor authentication token for the user. The one-time password is changed after every authentication and is generated using dynamic keys.

Meet compliance requirements

ISO 27001, ISO 27018, SOC 2, and other regulations and industry standards include authentication-related requirements, for example, multi-factor authentication (MFA) for accessing production systems, and the logging of all administrative sessions. In addition to other requirements, using SPS and YubiKey helps you comply with the following requirements:

  • PCI DSS 8.3: Secure all individual non-console administrative access and all remote access to the cardholder data environment (CDE) using multi-factor authentication.

  • PART 500.12 Multi-Factor Authentication: Covered entities are required to apply multi-factor authentication for:

    • Each individual accessing the covered entity’s internal systems.

    • Authorized access to database servers that allow access to nonpublic information.

    • Third parties accessing nonpublic information.

  • NIST 800-53 IA-2, Identification and Authentication, network access to privileged accounts: The information system implements multi-factor authentication for network access to privileged accounts.

  • The General Data Protection Regulation (GDPR) goes into effect on May 25, 2018, and is applicable to organizations keeping Personally identifiable information (PII) and offering goods or services to individuals based in the EU.

    YubiKey provides strong authentication to secure access to PII and comply with GDPR.

  • The Defense FAR Supplement (DFARS) clause went into effect on December 31, 2017, and is applicable to US Department of Defense (DoD) contractors to protect unclassified DoD information and minimize loss of information.

    The multi-protocol YubiKey meets DFARS requirements for strong authentication, and is the only hardware authentication solution to meet DoD contractor security requirements.

  • The revised Directive on Payment Services (PSD2) provides recommendations on standardized access to customer data and banking infrastructure, including draft regulatory technical standards specifying the requirements of strong customer authentication (SCA).

    Yubico and FIDO are playing active roles in the PSD2 framework with proven technology.

How SPS and YubiKey MFA work together

Figure 1: How SPS and YubiKey work together

  1. A user attempts to log in to a protected server.

  2. Gateway authentication on SPS

    SPS receives the connection request and authenticates the user. SPS can authenticate the user to a number of external user directories, for example, LDAP, Microsoft Active Directory, or RADIUS. This authentication is the first factor.

  3. Outband authentication on YubiKey

    If gateway authentication is successful, SPS connects the YubiKey server to check which authentication factors are available for the user. Then SPS requests the second authentication factor from the user. SPS supports authentication factors that are based on keyboard interaction such as Yubico-OTP, OATH-OTP, OATH-HOTP, and OATH-TOTP. For details on these authentication factors, see What is OATH?.

    For OTP-like authentication factors, SPS requests the one-time password (OTP) from the user, and sends it to the YubiKey Validation Service for verification either running on premise or using the YubiCloud Validation Service.

  4. If multi-factor authentication is successful, the user can start working, while SPS records the user's activities. (Optionally, SPS can retrieve credentials from a local or external credential store or password vault, and perform authentication on the server with credentials that are not known to the user.)

Technical requirements

In order to successfully connect SPS with YubiKey, you need the following components.

In YubiKey:
  • The users must have a YubiKey device and a means to map usernames to YubiKey Public IDs. For details, see YubiKey Multi-Factor Authentication - Tutorial and YubiKey Multi-Factor Authentication - Tutorial.

  • The YubiKey Client ID and API Key.

    For details on generating your Client ID and API Key, see How do I get an API key for YubiKey development?.

    To generate your Client ID and API Key, authenticate yourself using a Yubikey One-Time Password and provide your e-mail address as a reference at Yubico get API key.

    A Yubico OTP is a 44-character, one-use, secure, 128-bit encrypted Public ID and Password. The OTP is comprised of two major parts: the first 12 characters remain constant and represent the Public ID of the YubiKey device itself. The remaining 32 characters make up a unique passcode for each OTP generated.

    For example, in the following Yubico OTP, the characters cccjgjgkhcbb are the Public ID, and the remaining characters are the passcode.

  • YubiKey does not require network connectivity or access to a mobile phone device. Just touch or tap the YubiKey device to authenticate.

  • A One Identity Safeguard for Privileged Sessions appliance (virtual or physical), at least version 5 F1.

  • A copy of the SPS YubiKey plugin. This plugin is an Authentication and Authorization (AA) plugin customized to work with the YubiKey multi-factor authentication service.

  • SPS must be able to access the validation service.

    The connection also requires the Client ID and API Key.

Availability and support of the plugin

The SPS YubiKey plugin is available as-is, free of charge to every SPS customer from the Plugin Page. In case you need any customizations or additional features, contact our Professional Services Team.
