Method and devices are provided for controlling access of a device to a remote desktop or a remote application running on a remote desktop or application server using a remoting protocol. The method includes the following steps: setting up a connection between the device and the remote desktop or application server to establish or to an existing user session, using the remoting protocol; setting up a virtual channel within the connection using the remoting protocol; monitoring the device to determine a device state; sending the device state over the virtual channel to the application server; and determining based on the received device state if an access to the remote desktop or remote application running in the user session is allowed, and blocking the access if the access is due to the received state not allowed.
