One Identity Safeguard for Privileged Sessions 5.7.0 - Starling Multi-Factor Authentication - Overview

Introduction

This document describes how you can use the services of One Identity Starling 2FA to authenticate the sessions of your privileged users with One Identity Safeguard for Privileged Sessions (Safeguard for Privileged Sessions).

One Identity Safeguard for Privileged Sessions:

One Identity Safeguard for Privileged Sessions (Safeguard for Privileged Sessions) controls privileged access to remote IT systems, records activities in searchable, movie-like audit trails, and prevents malicious actions. Safeguard for Privileged Sessions 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.

Safeguard for Privileged Sessions acts as a central authentication gateway, enforcing strong authentication before users access sensitive IT assets. Safeguard for Privileged Sessions 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 Safeguard for Privileged Sessions'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 Starling (or another multi-factor authentication provider), Safeguard for Privileged Sessions directs all connections to the authentication tool, and upon successful authentication, it permits the user to access the information system.

Integrating One Identity Starling 2FA with Safeguard for Privileged Sessions:

Safeguard for Privileged Sessions can interact with your Starling 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 One Identity Starling 2FA, Safeguard for Privileged Sessions prompts the user for a second factor authentication, 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 Safeguard for Privileged Sessions. If the Starling 2FA App is installed on the user's device (smartphone, tablet, and so on), the user can generate a one-time password on the device. This will be used for the 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 a few seconds.

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 Safeguard for Privileged Sessions and Starling 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.

How Safeguard for Privileged Sessions and Starling 2FA work together

Figure 1: How Safeguard for Privileged Sessions and Starling 2FA work together

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

  2. Gateway authentication on Safeguard for Privileged Sessions

    Safeguard for Privileged Sessions receives the connection request and authenticates the user. Safeguard for Privileged Sessions 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 Starling

    If gateway authentication is successful, Safeguard for Privileged Sessions connects the Starling service to check which authentication methods are available for the user. Then Safeguard for Privileged Sessions requests the second authentication factor from the user.

    • For OTP-like authentication methods, Safeguard for Privileged Sessions requests the one-time password (OTP) from the user, and sends it to the Starling service for verification.

    • For the Starling push notification method, Safeguard for Privileged Sessions asks the Starling service to check if the user successfully authenticated on the Starling service.

  4. If multi-factor authentication is successful, the user can start working, while Safeguard for Privileged Sessions records the user's activities. (Optionally, Safeguard for Privileged Sessions 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.)
