Combining network endpoint policy results
View Patent ↗An endpoint integrity system controls access to resources of a protected network for endpoint devices attempting to access the protected network. The system may include a number of evaluation modules that communicate with an endpoint device. The evaluation modules generate policy results for the endpoint device, in which each of the policy results assume one of three or more states, called a multi-state policy result. The multi-state policy results are combined to produce a combined Boolean policy result.

each policy result, of the plurality of policy results, being associated with a respective plurality of states, and
a first plurality of states, associated with the first policy result, including:
a pass state,
a fail state, and
another state that differs from the pass state and the fail state;
determining, by the processor, information associated with a criterion,
the information identifying:
a first state of the first plurality of states, and
a second state of a second plurality of states associated with the second policy result;
evaluating, by the processor and based on the criterion, the network device to generate an evaluation result; and
outputting, by the processor, the evaluation result to the network device.

a first particular state, of the first plurality of states, associated with the network device for the first policy test, and
a second particular state, of the second plurality of states,
associated with the network device for the second policy test,
evaluate status information, based on a comparison of the first particular state and the second particular state to the expression, to form an evaluation result, and
forward, to the network device, a response to the request based on the evaluation result.
