at the server, determining that a deviation between the normal pattern of activity and the first pattern of activity associated with the first device is outside of a threshold deviation; and

upon the determination, generating alert information by the server, wherein the alert information when processed causes at least one of: the transmitting by the server of a message to an administrator; the blocking of the first device from accessing a service; and transmitting to the first device instructions to uninstall an application program on the first device.

7. The method of claim 6 , wherein the observation data collected comprises:

a first set of observation data associated with an organization and collected from a first subset of the plurality of devices associated with the organization, and

a second set of observation data collected from a second subset of the plurality of device not associated with the organization.

8. The method of claim 7 , wherein:

the first device is associated with the organization; and

the determining the normal pattern of activity occurring on the plurality of devices by processing the collected observation data comprises processing the collected observation data from the first subset of the plurality of devices and not processing the collected observation data from the second subset of the plurality of devices to determine the normal pattern of activity.
