Access Manager

Note: To display only the features present on a particular device, select one or more filters from the SmartDocs bar below.

EMDK For Xamarin - 5.0

Overview

The Access Manager (AccessMgr) enables an admin to configure a device to control which user or "installable" application(s) can be used on the device and what actions the application(s) can perform.

A key feature of AccessMgr is the ability to enable and disable "whitelisting," a process that allows only those applications explicitly specified in a list to run. Whitelisting is disabled by default and imposes no restrictions. When whitelisting is turned on, various restrictions can be applied using AccessMgr. Applications NOT included in the "whitelist" are prevented from running. AccessMgr allows whitelist applications to be installed, launched and maintained, and can control which applications are allowed to submit XML for all CSPs, including AccessMgr itself.

Whitelisting applies only to user applications and has no effect on System applications, which are applications built into the device and are therefore always present. To control aspects of System applications, see AppMgr.

User applications are those NOT built into the device and hence must be installed before they can be used. Whitelisting can be used to control whether a device user is allowed to install a user application, but cannot control whether an application can be installed programmatically by using AppMgr. Whitelisting also can be used to control whether a user application can be launched (by any means) once it is installed.

Note: It is important to understand that if an app uses AccessMgr to enable whitelisting, then that app becomes subject to whitelisting. If the app does not add itself to the "whitelist," the app is prevented from running. Also, if such an app does not explicitly allow itself to submit XML, it would be unable to alter that configuration once successfully applied.

AccessMgr also provides the option to control whether the device user can access a full or reduced version of the in-device Settings panel.

Main Functionality

Turn whitelisting on or off
Manage the "whitelist" of applications that a device user can install and launch
Turn verification of application signatures on or off
Control which applications are allowed to submit XML
Select whether the device user can access Full or Reduced Settings
Set Application Verification Mode to Verify All App Signatures
Allow, disallow and verify service binding
Allow, disallow and verify calls to a service
Designate CSPs on a device as "Protected" from access by apps
Approve apps for accessing CSPs designated as Protected

Operation Mode

This is the On/Off switch for Whitelisting, which restricts the apps that a device user can install and/or launch. Whitelisting is Off by default, imposing no restrictions. Whitelisting provides device security by preventing the installation and/or use of unauthorized apps, and by complicating the process of app deployment.

Application Verification Signing Mode

Controls whether Whitelisting verifies the signatures of apps, and if so, which app signatures are verified. Signature verification is turned off by default.

When Whitelisting is turned on but Signature verification is turned off, the determination of whether an application is on the "whitelist" is made solely by comparing the Android Package Name. This is insecure since it cannot prevent a potentially rogue application from setting it's Package Name to be one that is known to be on the "whitelist," and hence circumvent Whitelisting by impersonating a trusted application.

To increase security, Signature verification can be turned on. When Signature verification is turned on, the determination of whether an application is on the "whitelist" will be based on both its Package Name and its Signature. For that to work, the Signature must be provided for every application that is added to the "whitelist" so it can be compared against the actual Signature of that application.

Signature verification is more secure since only a specific "authentic" version, as identified by its Signature, of a given application, whose Package Name is on the "whitelist," will be allowed to be installed and launched. Turning on Signature verification also complicates the process of deploying applications since a unique Signature will need to be configured for each application as part of adding that application to the "whitelist."

Service Access Action

Used to control which "installable" (non-System) applications can call controllable services running on the device. This allows an administrator to manage access to the services present in a device and the ability of apps to bind to and leverage callable services. This can be used, for example, to prevent access to services relating to sensitive functionality, or to prevent use of such services when they are not explicitly required for a particular usage scenario or app.
