● OpenManage Essentials transmit alerts to Dell OpenManage Mobile Cloud Services (OMCS) using HTTPS as identified by
using a PKI certificate.
● Alerts are sent by using HTTPS to Google Cloud Messaging (GCM), or by using a binary protocol over TLS to the Apple Push
Notification Service (APNS). Google and Apple servers are also identified by a certificate.
● Android and Apple devices connect to Google and Apple servers respectively over a secure channel and retrieve the alert
push notifications.
Only limited information such as the number of new alerts is available outside the OMM application. Potentially-sensitive
information such as alert message contents are not shown on the device notification bar, app icons, or other mobile display
areas. Each mobile device supplies an application- and device-specific registration token to each OpenManage Essentials server
when it subscribes for alerts. The token is sent to and used by OMCS to identify the device to GCM and APNS. Without that
token, no other service can send push notifications to that OMM instance.
Apple and Google use certificates and API keys to identify OMCS as being associated with the OMM app. Similarly, OMCS
identifies OpenManage Essentials instances by using API key. OMM tracks the OpenManage Essentials instances that it is
subscribed to, so that it can discard alerts from subscriptions that have been removed. This helps prevent spurious or unwanted
notifications. Dell EMC does not persist the contents of alerts within OMCS.
