About Endpoint Management 编辑

Citrix Endpoint Management is a unified endpoint management (UEM) solution that brings every app and endpoint into one unified view to increase security and improve productivity. For an overview of UEM, see the Citrix Tech Zone technical brief, Citrix Endpoint Management.

Endpoint Management provides Mobile Device Management (MDM) and Mobile App Management (MAM).

MDM features of Endpoint Management let you:

• Deploy device policies and apps.
• Retrieve asset inventories.
• Carry out actions on devices, such as a device wipe.

MAM features of Endpoint Management let you:

• Secure apps and data on BYO mobile devices.
• Deliver enterprise mobile apps.
• Lock apps and wipe their data.

With a combination of MDM and MAM features, you can:

• Manage a corporate-issued device by using MDM
• Deploy device policies and apps
• Retrieve an asset inventory
• Wipe devices
• Deliver enterprise mobile apps
• Lock apps and wipe the data on devices

The following table summarizes the Endpoint Management features supported for MDM, MAM, or MDM+MAM.

Notes:

(1) Deployment ordering applies only to devices in a delivery group that has an enrollment profile configured for MDM.

(2) MAM enrollment requires Citrix Gateway.

(3) Workspace Environment Management (WEM) integration provides access to MDM features on a wide spectrum of Windows operating systems.

For more information, see Management modes.

Architecture

The device and app management requirements of your organization determine the Endpoint Management components in your Endpoint Management architecture. The components of Endpoint Management are modular and build on each other. For example, your deployment includes Citrix Gateway:

• Citrix Gateway gives users remote access to mobile apps and tracks user device types.
• Endpoint Management is where you manage those apps and devices.

The following diagram shows a general architectural overview of an Endpoint Management cloud deployment and its integration with your data center.

The following subsections contain reference architecture diagrams for:

• Endpoint Management
• Optional components such as an external Certificate Authority, Endpoint Management connector for Exchange ActiveSync, and Endpoint Management MDM+MAM and Intune MAM traffic flow.

For more information about Citrix ADC and Citrix Gateway requirements, see the Citrix product documentation at /wiki/citrix/.

Resource locations

Place resource locations where they best meet your business needs. For example, in a public cloud, in a branch office, private cloud, or a data center. Factors that determine the choice of location include:

• Proximity to subscribers
• Proximity to data
• Scale requirements
• Security attributes

You can build any number of resource locations. For example, you might:

• Build a resource location in your data center for the head office, based on subscribers and applications that require proximity to the data.
• Add a separate resource location for your global users in a public cloud. Alternatively, build separate resource locations in branch offices to provide the applications best served close to the branch workers.
• Add a further resource location on a separate network that provides restricted applications. This setup provides restricted visibility to other resources and subscribers without the need to adjust the other resource locations.

Cloud Connector

Cloud Connector authenticates and encrypts all communication between Citrix Cloud and your resource locations. Cloud Connector is required to access the following services: LDAP, IdPs, PKI Server, internal DNS queries, Citrix Virtual Apps, Citrix Gateway, Citrix Workspace, and Microsoft Endpoint Manager.

The following diagram shows the traffic flow for Cloud Connector.

Cloud Connector establishes connections to Citrix Cloud. Cloud Connector doesn’t accept incoming connections.

Cloud Connector is under load only during device enrollment. For more information, see Scale and size considerations for Cloud Connectors.

A solution that includes Mobile App Management (MAM) requires a micro VPN that is provided by an on-premises Citrix Gateway. In this scenario:

• The following components reside in your data center:
  • Cloud Connector
  • Citrix Gateway
  • Your servers for Exchange, web apps, Active Directory, and PKI
• Mobile devices communicate with Endpoint Management and your on-premises Citrix Gateway.

Endpoint Management components

Endpoint Management console. You use the Endpoint Management administrator console to configure Endpoint Management. For details about using the Endpoint Management console, see the articles under Endpoint Management. Citrix notifies you when the What’s new articles for Endpoint Management are updated for a new release.

Note these differences between the Endpoint Management service and the on-premises releases:

• The Remote Support client is not available for Endpoint Management.
• Citrix does not support syslog integration in Endpoint Management with an on-premises syslog server. Instead, you can download the logs from the Troubleshooting and Support page in the Endpoint Management console. When doing so, you must click Download All.

MAM SDK. The MDX toolkit is scheduled to reach EOL in July 2023. To continue managing your enterprise applications, you must incorporate the MAM SDK.

• The Mobile Application Management (MAM) SDK provides MDX functionality that isn’t covered by the iOS and Android platforms. You can MDX-enable and secure iOS or Android apps. You make those apps available in either an internal store or public app stores. See MDX App SDK.

Mobile productivity apps. Citrix-developed mobile productivity apps provide a suite of productivity and communication tools within the Endpoint Management environment. Your company policies secure those apps. For more information, see Mobile productivity apps.

Endpoint Management connector for Exchange ActiveSync. Endpoint Management connector for Exchange ActiveSync provides secure email access to users who use native mobile email apps. The connector for Exchange ActiveSync provides ActiveSync filtering at the Exchange service level. As a result, filtering only occurs once the mail reaches the Exchange service, rather than when it enters the Endpoint Management environment. The connector doesn’t require the use of Citrix Gateway. You can deploy the connector without changing routing for the existing ActiveSync traffic. For more information, see Endpoint Management connector for Exchange ActiveSync.

Citrix Gateway connector for Exchange ActiveSync. Citrix Gateway connector for Exchange ActiveSync provides secure email access to users who use native mobile email apps. The connector for Exchange ActiveSync provides ActiveSync filtering at the perimeter. The filtering uses Citrix Gateway as a proxy for ActiveSync traffic. As a result, the filtering component sits in the path of mail traffic flow, intercepting mail as it enters or leaves the environment. The connector for Exchange ActiveSync acts an intermediary between Citrix Gateway and Endpoint Management. For more information, see Citrix Gateway connector for Exchange ActiveSync.

Endpoint Management technical security overview

Citrix Cloud manages the control plane for Endpoint Management environments. The control plane includes the Endpoint Management server, Citrix ADC load balancer, and a single-tenant database. The cloud service integrates with a customer data center using Citrix Cloud Connector. Endpoint Management customers who use Cloud Connector typically manage Citrix Gateway in their data centers.

The following figure illustrates the service and its security boundaries.

The information in this section:

• Provides an introduction to the security functionality of Citrix Cloud.
• Defines the division of responsibility between Citrix and customers for securing the Citrix Cloud deployment.
• Isn’t configuration or administration guidance for Citrix Cloud or any of its components or services.

For information about the technology used by Endpoint Management to deliver comprehensive, end-to-end security, see the Citrix whitepaper, Citrix Endpoint Management Security Overview.

Data flow

The control plane has limited read access to user and group objects. Those objects reside in your directory, DNS, and similar services. The control plane accesses those services over Citrix Cloud Connector through secure HTTPS connections.

Company data, such as email, intranet, and web-app traffic, flows directly between a device and the application servers over Citrix Gateway. Citrix Gateway is deployed in the customer data center.

Data isolation

The control plane stores metadata needed for managing user devices and their mobile applications. The service itself consists of a mix of multi- and single-tenant components. However, per the service architecture, customer metadata is always stored separately for each tenant and secured by using unique credentials.

Credential handling

The service handles the following types of credentials:

• User credentials: User credentials are transmitted from the device to the control plane over an HTTPS connection. The control plane validates these credentials with a directory in the customer directory over a secure connection.
• Administrator credentials: Administrators authenticate against Citrix Cloud, which uses the sign-on system from Citrix Online. This process generates a one-time signed JSON Web Token (JWT), which gives the administrator access to the service.
• Active Directory credentials: The control plane requires bind-credentials to read user meta-data from Active Directory. These credentials are encrypted using AES-256 encryption and saved in a per-tenant database.

Deployment considerations

Citrix recommends that you consult the published best practices documentation for deploying Citrix Gateway within your environments.
