Overview

The Access Manager (AccessMgr) enables the configuration of a device to control which user, or "installable" application(s) can be used on a given device as well as what the application(s) can do.

A key feature of AccessMgr is the ability to turn Whitelisting on or off. Whitelisting is off by default, imposing no restrictions. When Whitelisting is turned on, various restrictions can be applied using AccessMgr.

Whitelisting is a process that allows only those applications explicitly specified in a list to run. Applications not included in the "whitelist" are prevented from running. AccessMgr allows whitelist applications to be installed, launched and maintained. AccessMgr also allows control of which applications are allowed to submit XML for all CSPs, including AccessMgr itself.

Whitelisting applies only to user applications and will never have an effect on System applications. System applications are those applications that are built into the device and hence are always installed. Some control of System applications can be accomplished by using AppMgr.

User applications are those applications that are not built into the device and hence must be installed onto a device 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 a user application uses AccessMgr to turn on Whitelisting, then that application will become subject to Whitelisting. If the application does not add itself to the "white" list, then that application will no longer be allowed to run. Also, if such an application does not explicitly allow itself to submit XML, then it would not be able to alter the configuration once it was 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

Operation Mode

Select the desired Operation Mode which will turn Whitelisting on or off. Whitelisting is turned off by default, and hence no restrictions are imposed on which applications device users can install or which applications can be launched.

Turning on Whitelisting allows a device to be made more secure by preventing a device user from installing applications that are not on the "white" list and by preventing all launching of applications that are not on the "white" list. Turning on Whitelisting also complicates the process of deploying applications since applications that are deployed and installed will have to also be added to the "white" list before they can be launched.

Parm Name: OperationMode

Option Name Description Note Requires
1 Single User without Whitelist This value will cause Whitelisting to be turned off and hence disable all Whitelisting functionality.

OSX: 1.0+

MX: 4.1+

2 Single User with Whitelist This value will cause Whitelisting to be turned on and hence enable Whitelisting functionality. The exact behavior of Whitelisting will depend on the configuration of the other parms.

OSX: 1.0+

MX: 4.1+

System Settings Access

Select the level of system settings access to be allowed on the device's System Settings menu.

Shown if: The Operation Mode is "Single User With Whitelist"

Parm Name: SystemSettings

Option Name Description Note Requires
1 Full Access This value will cause the device user to be allowed to access the full capabilities of the in-device System Settings Menu.

OSX: 3.5+

MX: 4.1+

2 Reduced Access This value will cause the device user to be allowed to access only a reduced set of the capabilities of the in-device System Settings Menu (Display, Volume, About)

OSX: 3.5+

MX: 4.1+

Application Verification Signing Mode

This parm allows you to control whether Whitelisting will verify the signatures of applications, and if so, which application signatures will be 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 "white" list 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 "white" list, 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 "white" list 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 "white" list 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 "white" list, 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 "white" list.

Shown if: The Operation Mode is "Single User With Whitelist"

Parm Name: AppVerifySignMode

Option Name Description Note Requires
0 Do not change This value (or the absence of this parm from the XML) will cause no change to whether Signature verification will occur or for which applications.

OSX: 3.5+

MX: 4.3+

1 Do not verify app signature This value will cause Signature verification to be turned off, thus causing Package Names alone to be used in to determine if an application is on the "white" list.

OSX: 3.5+

MX: 4.3+

2 Verify user app signature This value will cause Signature verification to be turned on, thus causing Signature verification to be used in addition to Package Names to determine if a user, or "installable," application is on the "white" list.

OSX: 3.5+

MX: 4.3+

3 Verify all apps signature This value will cause Signature verification to be turned on, thus causing Signature verification to be used in addition to Package Names to determine if any application, "built-in" or "installable," is on the "white" list.

OSX: 3.5+

MX: 4.3+

Delete Packages

Select whether or not to delete Packages from the Whitelist

Shown if: The Operation Mode is "Single User With Whitelist"

Parm Name: DeletePackagesAction

Option Name Description Note Requires
0 Delete NO Packages This value does not delete anything and hence does not affect the "white" list at all.

OSX: 1.0+

MX: 4.1+

1 Delete specified Packages(s) This value will cause one or more selected Package Names to be deleted from the "white list," thus blocking user, or "installable," applications with those Package Names from being installed by the device user or launched.

OSX: 1.0+

MX: 4.1+

2 Delete ALL Packages This value will cause all Package Names to be deleted from the "white list," thus blocking all user, or "installable," applications from being installed by the device user or launched.

OSX: 1.0+

MX: 4.1+

3 Delete specified Signature(s) This value is meaningful only with Signature verification is turned on, in which case it deletes one or more Signatures from the "white list," thus blocking user, or "installable," applications with those Signatures from being installed by the device user or launched.

OSX: 1.0+

MX: 4.1+

Delete Package Name(s)

Provide the Package Names to be deleted from the "white" list.

Parm value input rules:

  • String with a minimum size of 1 character
  • Package names must be separated by commas, such as "com.mycompany.mypackage,com.mycompany2.mypackage2"

Shown if: The Operation Mode is "Single User With Whitelist" *AND* Delete Packages is "Delete specified Packages(s)"

Parm Name: DeletePackageNames

Add Packages

Select whether or not to add Packages to the "white" list. Adding an application to the "white" list using this parm does not allow the application to submit XML, that must be done using the separate parm "Add Packages and Allow to Submit XML."

Note: It is important to understand that if an application uses the AccessMgr to turn on Whitelisting, then that application will become subject to Whitelisting. If the application does not add itself to the "white" list, then that application will no longer be allowed to run. Also, if such an application does not explicitly allow itself to submit XML, then it would not be able to alter the configuration once it was successfully applied.

Shown if: The Operation Mode is "Single User With Whitelist"
