Working with attachment security settings

You can control how HCL Traveler clients manage file attachments and images.

All modern mobile devices have built in capabilities which allow file data to be shared between applications. File data in the form of attachments to Domino mail messages, Domino calendar events, and Domino To Do documents is allowed by default to sync using HCL Traveler from the Domino mail server to the mobile device. Once this file data is available on the device, it is possible to share it with other third party applications on the device that support file data of the same type. For example, data for a presentation file could be shared with a presentation editor or viewer. Being able to use third party applications is a very powerful ability, and can greatly improve the usefulness of mobile devices and overall productivity. However, there can be security concerns for what happens with this data once it is obtained by a third party application.

HCL Traveler attachment security settings are used to control how HCL Traveler clients manage file attachments and images. When these settings are enabled, the client restrict file attachments and images from being shared with third party applications unless these applications have been approved by the HCL Traveler administrator.

Alternatively, Mobile Application Management (MAM) providers can provide data sharing and export controls which do not rely upon the HCL Traveler attachment security settings. For more information on options available to MAM providers for controlling data sharing and exporting of attachments with the HCL Domino Workspace Mail clients, see the following articles:

HCL Domino Workspace Mail for Android devices

HCL Domino Workspace Mail for Android devices requires approved applications be defined in order to view attachment data. There are no viewer controls built into the Android OS or HCL Traveler at this time. If attachment security settings are enabled, then you must define approved applications in order to access any of the attachment data on mobile devices. Approved applications are applications that have been "approved" by the administrator for attachment handling. This generally implies that the administrator has done some amount of testing with the application and is familiar enough with it to know that it will not leak attachment data outside itself. The HCL Traveler attachment security settings only enforce the attachment data contained within the HCL Traveler mail account or To Do application, and is shared with applications in the approved list. Once the attachment data is consumed by another application, HCL Traveler can no longer control what happens to it.

To create the definitions for approved applications, see Defining approved applications for Android devices.
