Patent ID: 8621574

Claim:
A computing system comprising: a processor and computer storage; an access control component to control access to system services and data using a number of access states including a blocked state, an allowed state, a device discovery state, and a quarantined state by: receiving a service request including device parameters from a device requesting the system services and data; associating a synchronization time with the service request; blocking the device from the system services and data using the blocked state if a trust level is less than a requisite trust level required by the computing system; allowing the device to access and use the system services and data using the allowed state if the trust level is greater than or equal to the requisite trust level; artificially quarantining the device using the device discovery state if recently introduced to the computing system including temporarily delaying access and use of the system services and data while determining the trust level of the device; quarantining the device to prevent access and use of the system services and data using the quarantined state if the trust level of the device is unknown, the quarantining including providing quarantine data to the device without providing the requested services and data to the device; and, storing the access state of the device in the computer storage.
