A strategy is described for controlling access to a resource which is shared between a trusted environment and an untrusted environment. The resource can represent a clipboard module. The trusted environment can include trusted client functionality, while the untrusted environment can include potentially untrusted network-accessible entities (e.g., websites) which seek to access the clipboard module. The strategy provides a security presentation which notifies a user when a network-accessible entity is attempting to access the clipboard module, identifying the entity which is making the attempt, together with the nature of the information being read or added to the clipboard module. The security presentation invites the user to approve or deny the particular attempt (or all such attempts from the network-accessible entity), and/or clear the clipboard module. The security presentation does not block the user's interaction with other parts of a user interface presentation.

Strategies for controlling use of a resource that is shared between trusted and untrusted environments

Various embodiments enable local web applications to communicate asynchronously with web based services and applications based on a local device's current state and a user's communications preferences. In at least some embodiments, a synchronization engine receives a message in a 'Web Inbox' from a web based service or application. In at least some embodiments, the synchronization engine notifies a local web application of the message, sends the message to the web application, and/or loads the web application if it is not in session. The web application's response to the message may be transferred to a 'Web Outbox' where it resides until being sent to the web service. The synchronization engine then determines a time to transmit the response to the web service by querying the local device for its current state and a user's communication preferences.
