4 Introduction Samsung, the mobile device market leader, has introduced Samsung KNOX for its Android-based mobile platforms to satisfy the device management and security needs of business and government customers. The purpose of this document is to provide a detailed overview of the enterprise integration and management features in Samsung KNOX with a focus on its capabilities for Microsoft Active Directory integration, policy management, Enterprise Mobility Management and Single Sign-On. Readers are also encouraged to consult the following additional resources: Samsung: White Paper: An Overview of Samsung KNOX Samsung: Introducing Samsung KNOX Samsung: Samsung KNOX website Samsung: Samsung for Enterprise (SAFE) website Gartner: Strategies to Solve Challenges of BYOD in Enterprise Centrify: Centrify and Samsung Partnership website Centrify: "An Introduction to Samsung KNOX" YouTube video Centrify: An Overview of Samsung KNOX Active Directory-based Single Sign-On Centrify: All Things KNOX Resource Center Samsung Android overview Samsung has quickly grown in the mobile space to become the leading provider of smartphones and tablets. Much of this growth has been fueled by its adoption of Android as a major platform for its mobile device offerings. Android is a popular open source-based operating system that is under the governance of Google. Even though Android has only been publicly available since 2008, it has been widely adopted by manufacturers and mobile users. In fact, by most measures, Android is the leading mobile operating system. Samsung was one of the early adopters of Android technology and has become the leading provider of Android-based smartphones and tablets. While Android has been popular with consumers, enterprise and government customers have been reluctant to endorse or deploy Android. This reluctance has been based on three major factors: 1. Since the Android operating system can be changed and the distribution of apps is not controlled by a single source, Android has been considered less secure and more prone to malware than other mobile platforms CENTRIFY CORPORATION.

5 2. Most Android platforms do not have the enterprise features that business and government IT managers require and are available on other mobile platforms, including centralized Enterprise Mobility Management, policy-based management, encryption and other key features. 3. Android does not have a way to segregate business data and apps from personal data and apps. This co-mingling of business and personal workspaces can lead to unprotected business data being leaked or compromised. In fact, until recently, many IT managers felt that Blackberry phones were the only options that addressed security requirements and enterprise needs. But this is changing. Samsung announced its SAFE (Samsung for Enterprise) program in 2012 to address some of these needs. Now, with the release of Samsung KNOX for supported Samsung Android-based mobile devices, Samsung and its partners go even further with state-of-the-art enterprise features and security enhancements that meet or exceed even the most stringent business and government needs. In addition, Samsung provides new technology to segregate users business and personal lives allowing one device to be used for both business and personal scenarios while ensuring optimal privacy and security. What is Samsung KNOX? Samsung KNOX is a new Androidbased solution specifically designed to enhance security of the current open source Android platform. KNOX is not a product or a single feature; instead it is a suite of enhancements to certain Samsung Android devices designed to address the needs of government and enterprise IT managers as well as employees. It is important to note that while many of these features are unique to the Samsung KNOX platform, Samsung has maintained full compatibility with Android and the Google ecosystem so that existing Android applications will continue to work on Samsung KNOX devices. Samsung starts with the latest Google Android mobile operating system platform and adds capabilities, or addresses shortcomings, in four key areas: 2013 CENTRIFY CORPORATION. ALL RIGHTS RESERVED. PAGE 2

6 1. Platform Security: Ultra-secure operating system services. 2. Application Security: Enhanced application security and runtime features. 3. Government and High Security Features: Features for Defense and Government customers who must comply with enhanced security, data access and data handling standards. 4. Enterprise Mobility Management: Best-in-class enterprise device management. By implementing these features, Samsung KNOX substantially enhances not only the Android user experience but also the security and manageability of the platform. The following section provides a brief overview of the core components of each of these sets of enhancements. For more detailed information on these features, please refer to the resources listed at the beginning of the document as well as information available on the All Things KNOX Resource Center. Platform Security At the hardware and operating system security level, Samsung KNOX provides powerful, unique platform security enhancements which prevent tampering with the device. These enhancements include: Customizable Secure Boot: Secure Boot is a procedure that prevents unauthorized operating systems and software from loading during the startup process. Firmware images that are cryptographically signed by known, trusted authorities are considered authorized firmware. Security Enhancements for Android: Security-Enhanced Linux (SE Linux) was invented by the NSA in 2000 and is a port of Linux that includes numerous security enhancements. Samsung R&D teams have worked very closely with the NSA to port and integrate this technology into Android. TrustZone-based Integrity Measurement Architecture: Samsung s TrustZone-based Integrity Measurement Architecture (TIMA) was developed as a unique feature on Samsung mobile devices. TIMA uses ARM TrustZone hardware and runs in a secure mode that cannot be disabled and provides continuous integrity monitoring of the Android kernel CENTRIFY CORPORATION. ALL RIGHTS RESERVED.

7 Application Security Samsung KNOX also includes features to enhance security at the application layer. These features include: Application Containers: Samsung s container technology is one of the most innovative additions to Samsung KNOX. This is a virtual Android environment that runs on the device and includes its own home screen, launcher and application environment. Applications and data in the container are completely isolated from applications and data outside the container. This allows the user to securely run business applications in the container while still having the ability to run personal applications outside the container in the standard Android environment. Data stored in one environment cannot be accessed or shared with the other environment. On-device Data Encryption: This feature allows users and administrators to encrypt data on the entire device, as well as any configured Samsung KNOX Container. Encryption is often required by government and regulated industries such as healthcare and finance. Virtual Private Network Support: Samsung KNOX includes support for virtual private networking (VPN). A unique feature of this implementation is the ability to set up different VPNs for each application. This allows secure communications to corporate networks for business applications while consumer applications can continue to function outside the VPN structure. Government and High Security Features Taken together, these security enhancements enable a mobile platform that can meet the strictest requirements of government and security-conscious enterprise customers. In addition, the KNOX platform complies with a number of government and security standards. These features and standards include: Smartcard CAC support utilizing both software and hardware Public Key Infrastructure (PKI) certificates. FIPS Level 1 certification for both data-at-rest (DAR) and data-in-transit (DIT). Compliance with the Defense Information Systems Agency (DISA) June 2012 version of the Security Requirements Guides (SRGs) specification CENTRIFY CORPORATION. ALL RIGHTS RESERVED. PAGE 4

8 Enterprise Mobility Management The final set of features available with Samsung KNOX addresses securing and managing the device by leveraging enterprise systems management solutions that are already in use in large organizations. These features make it easier to centrally control the device and apply consistent policies across all KNOX devices in the enterprise. Many of these features also provide users with a better experience by allowing them to self-manage tasks such as changing enterprise passwords or employing a single set of credentials to access all enterprise applications (also known as Single Sign- On). The container can be centrally managed by a corporate administrator from within Microsoft Active Directory. Before covering these important features, it is worth reviewing why organizations need these features and look at tools that are in use for managing users and other devices within the enterprise. Why IT organizations care about Enterprise Mobility Management One of the biggest challenges for IT administrators in a large enterprise is managing and securing a diverse range of computing devices. Over the last decade, solutions for managing personal computers have flourished and organizations can now centrally manager computers, deploy applications to these devices, impose policies on the use of the devices (including enforcing role-based policies) and manage access to the device through authentication and authorization tools. Most organizations have chosen to supply approved computers to their users which have already been setup with the necessary tools to manage the device centrally. More recently, users are increasingly turning to small, mobile, instant-on devices such as smartphones and tablets instead of computers for daily computing tasks. Likewise, organizations are seeing the benefits of using mobile devices to empower workers who are on the go. Yet, with these positive trends, there are a number of issues which challenge enterprise IT administrators including: Users who own their own mobile devices want to bring them to work and use them in their jobs. This introduces potential security, application deployment and management challenges which need to be solved by IT staff with the involvement of the end user before these devices can be deployed. Thousands of different mobile devices with dozens of different operating systems are now available each with their own challenges for deployment in enterprises. Therefore, many organizations only allow a limited number of known, tested devices to be used within the corporate network. IT managers want to be able to centrally control and remotely wipe devices, yet corporate device control becomes less feasible if these devices are owned by the end user and contain personal data in addition to corporate data. Mobile devices have the potential to carry sensitive enterprise data, yet with these devices always connected to the Internet, there is the potential for unintentional or even malicious 2013 CENTRIFY CORPORATION.

9 disclosure of information to outside parties. In addition, if devices are not secured with a passcode, enterprise information could be disclosed if the device is borrowed, lost or stolen. With users loading their own applications and accessing remote sites on the Internet, there is a constant concern about the possibility of viruses or malware that could compromise corporate data. In addition, mobile devices that organizations want to use are often not the same ones that end users have or want to use. To address these and other challenges, a number of vendors have emerged with non-integrated solutions for Enterprise Mobility Management. For organizations that have existing personal computers, especially Microsoft Windows-based computers, having a way to extend existing enterprise user and device management practices and solutions to mobile devices is highly desirable. With Samsung KNOX, these capabilities become a possibility on supported mobile devices. Microsoft Active Directory and Group Policy Management Organizations that have large numbers of Windows-based computers typically use Microsoft s server technologies as the underlying IT infrastructure for managing their users and devices. The foundation of Microsoft s infrastructure is Active Directory. Active Directory is essentially a database which stores information about users and devices and is wrapped in services that allow users and devices to join a secure corporate domain, authenticate users when they login, store preferences and provide other administrative tasks. Active Directory acts as the base for many other management services such as certificate services, rights management, domain services and group policy. Group Policy enables policy-based administration using Microsoft Active Directory. Group Policy uses directory services and security group membership to provide enforceable rules for users and devices that can be set by the administrator and applied across the corporate network. Policy settings are created using the Microsoft Management Console (MMC) snap-in for Group Policy and can be applied to resources based on rules, membership, roles or globally to all devices and users. While Active Directory, Group Policy and other Microsoft server-based technologies have been traditionally used to manage Windows-based resources, the services are extensible thereby allowing companies like Centrify Corporation to create solutions for joining non-microsoft devices, such as Apple Macs, Linux computers and UNIX servers to an Active Directory-based corporate IT infrastructure. More recently, Centrify has created solutions to enable mobile devices to join and be managed by the Active Directory system. Samsung has licensed this technology and includes it in its KNOX offerings. Given that Active Directory is used by a majority of enterprises, these capabilities significantly enhance the ability of enterprises to extend device and user management, authentication, and policy-based management to all KNOX-enabled devices. Administrators benefit by being able to centrally manage users and devices from a single console including the ability to allow or deny user access to corporate computing resources. Users benefit by having a consistent experience and a single set of login credentials for all resources managed by the enterprise CENTRIFY CORPORATION. ALL RIGHTS RESERVED. PAGE 6

10 Background on Centrify Centrify provides Unified Identity Services across data center, cloud and mobile resulting in one single login for users and one unified identity infrastructure for IT. Centrify's software and cloud services let organizations securely leverage their existing identity infrastructure to centrally manage authentication, access control, privilege management, policy enforcement and compliance across onpremise and cloud resources. More than 5000 customers have deployed Centrify across millions of computers, applications and mobile devices to increase agility and security. With Centrify, organizations are reducing the costs associated with identity lifecycle management and compliance by over 50%. Since releasing its initial product in 2005, Centrify has expanded its portfolio from one product to a suite of software and cloud services that span data center, cloud and mobile environments with comprehensive support for over 450 systems and 1,500+ applications. Overview of Centrify s features in KNOX Centrify technology has been licensed by Samsung to enhance KNOX in three core areas of the platform: Active Directory-based mobile container management, Single Sign-On (or more aptlynamed Zero Sign-On ) for enterprise apps and a software development kit for software vendors and organizations who want to extend Zero Sign-On to their own applications. Container management As mentioned earlier, Samsung has developed container technology which allows administrators to create a secure and distinct business environment on any KNOX-enabled mobile device. Only approved applications can run in this environment and data associated with these applications can only be accessed from within the container. Once a container is created on a Samsung KNOX device, it can be secured through Centrify s integration services which tie back to Active Directory. This means that the container can join the Active Directory domain and appear as a managed device within the Active Directory corporate infrastructure. Administrators have full control over the container and can control user access to the container s apps and data. The administrator can also deploy and manage applications that are secured within the container. This gives users the freedom to carry one device for both work and play via a seamless and intuitive dual persona experience. Both personal and business data are kept segregated and private CENTRIFY CORPORATION. ALL RIGHTS RESERVED. PAGE 7

11 Active Directory-based authentication and mobile device / container management Active Directory is deployed to manage users within an organization and for authenticating users when they log in to a device. The user s profile as well as group memberships is stored in Active Directory which can be used to control access to different IT resources. For example, if Mary Smith just joined your organization s sales team, the IT administrator would add her to Active Directory, setup up her profile information and provide her with a login password. The administrator would also add her to various sales-related security and distribution groups which would allow her to securely access the sales resources of the organization. In addition, computers that Mary uses at work could be joined to Active Directory ensuring that her devices are authenticated on the corporate network and are managed based on the organization s IT policies. With Samsung KNOX, Centrify extends Active Directory to Android-based containers. This means that the container is joined and secured through Active Directory. This benefits administrators since they can centrally control all of their users devices from a single console. If a user leaves an organization, administrators can not only turn off access to the corporate container on the KNOX device they can delete the container and remove all corporate applications and data. All this happens without impacting the user s personal applications and data that reside outside the corporate container. Group Policy-based management In addition to creating and removing containers, administrators also have access to fine-grained management of the KNOX device using Group Policy. As mentioned earlier, Group Policy works within the Active Directory infrastructure to allow managers to create IT policies such as password complexity requirements and have those policies enforced throughout the enterprise. Most IT administrators use Group Policy to manage their computers within the corporate network. Now with Centrify s technology in KNOX, administrators can manage KNOX containers, control access to containers and enforce corporate or mobile-specific policies within containers. All this happens from within the standard Group Policy console, which means administrators do not have to install different costly tools or learn different techniques for managing their mobile devices. For example, the administrator can view all end-user devices and drill down to see specific details related to the enduser s KNOX device. Policies such as allowing VPN or Wi-Fi access or configuring a firewall can also be pushed to the mobile device. Or the administrator can send a command to the KNOX device to create 2013 CENTRIFY CORPORATION. ALL RIGHTS RESERVED. PAGE 8

12 a secure corporate container and pre-populate that container with approved corporate applications or setup an account. Policies can also be related to roles. For example, a policy could be set up to grant all sales employees access to the corporate sales portal. There are over 470 policies that can be used with KNOX which leverage over a thousand management APIs. Single Sign-On for mobile and web apps Single Sign-On is a concept that allows users to log in to the corporate network one time and from there have full access to approved corporate resources, applications and data without having to reenter their credentials for each action. By extending applications using standards-based SAML and Kerberos technology, secure tokens can be used across a wide range of popular business applications. For example, a user could log in to his or her computer using his or her Active Directory username and password and then be able to launch local and web-based applications by just clicking on an icon without having to enter credentials for each application. Access to these applications is managed centrally meaning that access can be turned on or off for each user or groups of users from a central administrative console. Another benefit of Single Sign-On is instead of having to remember complex conforming passwords for each site or application, authentication is handled by the Single Sign-On system. In addition, users will be less temped to use insecure passwords or the same password across multiple sessions. Centrify has taken these concepts and extended them to Samsung KNOX and beyond. Now, administrators can setup a worker s environment for both web applications and native mobile apps on supported mobile devices. This includes setting up access and the Single Sign-On attributes for each application. Applications could include native apps such as Box or web-based SaaS (Software as a Service) applications such as Salesforce.com. These applications are then run from within the user s secure KNOX container on his or her KNOX device. In addition, Centrify provides a secure web-based user portal for running SaaS applications from any device that has a web browser. Administrators can also manage access from a browser-based console. Both these classes of web-based applications connect to authentication and access services 2013 CENTRIFY CORPORATION. ALL RIGHTS RESERVED. PAGE 9

13 through the Centrify Cloud Service and the Centrify Proxy Server which interfaces with the organization s Active Directory infrastructure. Once users provide their password to access the container on their KNOX devices, they are taken to a Zero Sign-On experience and given direct access to their applications. Administrators benefit by having central control over IT apps and data while users benefit by having a simple, seamless experience moving from one app to the next without having to remember and enter complex passwords for each action. Mobile Authentication Services (MAS) Software Development Kit (SDK) In order to extend Single Sign-On capabilities to as many developers as possible, Centrify has built the Mobile Authentication Services (MAS) Software Development Kit (SDK), which is available from both Centrify and Samsung. This SDK includes the tools and libraries to allow corporate and ISV Android app developers to add Single Sign-On capabilities to their own mobile apps. In addition, developers have access to hundreds of KNOX and SAFE APIs which enable better security and management functionality for mobile applications. ISVs such as Box and Onvelop are part of a growing list of ecosystem partners which have used this SDK to enable Single Sign-On for their apps running on KNOX devices CENTRIFY CORPORATION.
