Risk-based cloud profile management for VDI in the cloud

1. A method of storing, in cloud storage, user data generated during a remote desktop session to a cloud computing system, the method comprising:

provisioning a plurality of storage containers, including a first storage container and a second storage container, in the cloud storage;

determining a risk level of the remote desktop session; and

storing the user data in the first storage container but not in the second storage container if the determined risk level of the remote desktop session is at a first level, and in the first and second storage containers if the determined risk level of the remote desktop session is at a second level that is lower than the first level.

2. The method of claim 1 , wherein the remote desktop session is established between an end user device of a user and a virtual machine provisioned in the cloud computing system, and the cloud storage is provided by the cloud computing system.

3. The method of claim 1 , wherein the risk level is determined from a score that is computed based on a login behavior of a user of the remote desktop session.

4. The method of claim 1 , wherein the risk level is determined from a score that is computed based on a location from which an end user device is logged into the remote desktop session.

5. The method of claim 1 , wherein the risk level is determined from a score that is computed based on a type of a network to which an end user device logged into the remote desktop session is connected.

6. The method of claim 1 , wherein

the first storage container is associated with a first key for encrypting content to be stored therein, and the second storage container is associated with a second key for encrypting content to be stored therein, the first key being more secure than the second key, and

the method further comprises encrypting the user data with the first key when the user data is stored in the first storage container, and with the second key when the user data is stored in the second storage container.

7. The method of claim 1 , wherein

the plurality of storage containers further includes a third storage container,

the user data is not stored in the third storage container if the determined risk level of the remote desktop session is at the first level and the second level, and

the method further comprises storing the user data in the first, second, and third storage containers if the determined risk level of the remote desktop session is at a third level lower than the second level.

8. The method of claim 1 , further comprising:

selecting the first storage container if the determined risk level of the remote desktop session is at the first level, and the second storage container if the determined risk level of the remote desktop session is at the second level; and

during the remote desktop session, retrieving stored user data from the selected storage container.

9. The method of claim 1 , further comprising:

after logging into the remote desktop session and prior to logging out of the remote desktop session, upon detecting that an end user device has disconnected from the remote desktop session and then reconnected to the remote desktop session, determining a new risk level of the remote desktop session; and

if the new risk level is higher than the risk level of the remote desktop session prior to the disconnection and the reconnection, forcibly logging out the end user device from the remote desktop session.

10. The method of claim 1 , further comprising:

after logging into the remote desktop session and prior to logging out of the remote desktop session, upon detecting that the end user device has disconnected from the remote desktop session and then reconnected to the remote desktop session, determining a new risk level of the remote desktop session; and

if the new risk level is higher than the risk level of the remote desktop session prior to the disconnection and the reconnection, closing all sensitive applications currently running in the remote desktop session, selecting another storage container, importing user data from said another storage container into memory, and reopening the sensitive applications.

11. A non-transitory computer-readable medium comprising instructions to be executed in a computer system, wherein the instructions when executed in the computer system cause the computer system to carry out a method of storing, in cloud storage that is provisioned with a plurality of storage containers, user data generated during a remote desktop session to a cloud computing system, the method comprising:

determining a risk level of the remote desktop session; and

storing the user data in a first storage container but not in a second storage container if the determined risk level of the remote desktop session is at a first level, and in the first and second storage containers if the determined risk level of the remote desktop session is at a second level that is lower than the first level.

12. The non-transitory computer-readable medium of claim 11 , wherein the remote desktop session is established between an end user device of a user and a virtual machine provisioned in the cloud computing system, and the cloud storage is provided by the cloud computing system.

13. The non-transitory computer-readable medium of claim 11 , wherein the risk level is determined from a score that is computed based on a login behavior of a user of the remote desktop session.

14. The non-transitory computer-readable medium of claim 11 , wherein the risk level is determined from a score that is computed based on a location from which an end user device is logged into the remote desktop session.

15. The non-transitory computer-readable medium of claim 11 , wherein the risk level is determined from a score that is computed based on a type of a network to which an end user device logged into the remote desktop session is connected.

16. The non-transitory computer-readable medium of claim 11 , wherein

the first storage container is associated with a first key for encrypting content to be stored therein, and the second storage container is associated with a second key for encrypting content to be stored therein, the first key being more secure than the second key, and

the method further comprises encrypting the user data with the first key when the user data is stored in the first storage container, and with the second key when the user data is stored in the second storage container.

17. The non-transitory computer-readable medium of claim 11 , wherein

the plurality of storage containers further includes a third storage container,

the user data is not stored in the third storage container if the determined risk level of the remote desktop session is at the first level and the second level, and

the method further comprises storing the user data in the first, second, and third storage containers if the determined risk level of the remote desktop session is at a third level lower than the second level.

18. The non-transitory computer-readable medium of claim 11 , wherein the method further comprises:

selecting the first storage container if the determined risk level of the remote desktop session is at the first level, and the second storage container if the determined risk level of the remote desktop session is at the second level; and

during the remote desktop session, retrieving stored user data from the selected storage container.

19. The non-transitory computer-readable medium of claim 11 , wherein the method further comprises:

after logging into the remote desktop session and prior to logging out of the remote desktop session, upon detecting that an end user device has disconnected from the remote desktop session and then reconnected to the remote desktop session, determining a new risk level of the remote desktop session; and

if the new risk level is higher than the risk level of the remote desktop session prior to the disconnection and the reconnection, forcibly logging out the end user device from the remote desktop session.

20. The non-transitory computer-readable medium of claim 11 , wherein the method further comprises:

after logging into the remote desktop session and prior to logging out of the remote desktop session, upon detecting that the end user device has disconnected from the remote desktop session and then reconnected to the remote desktop session, determining a new risk level of the remote desktop session; and

if the new risk level is higher than the risk level of the remote desktop session prior to the disconnection and the reconnection, closing all sensitive applications currently running in the remote desktop session, selecting another storage container, importing user data from said another storage container into memory, and reopening the sensitive applications.
