Abstract:
1. A method of operating a data network including a first network device and a second network device, the method comprising: providing data for distribution from the first network device to the second network device; providing a first risk factor associated with the data wherein the first risk factor characterizes a sensitivity of the data with the respect to unauthorized access to the data; providing a second risk factor associated with the second network device wherein the second risk factor characterizes a degree of network intrusion associated with the second net work device; assessing a risk of distribution based on consideration of the first and second risk factors; blocking the distribution of data to the second network device if the risk of distribution exceeds a threshold; and allowing the distribution of data to the second network device if the risk of distribution does not exceed the threshold; wherein assessing the risk of distribution comprises summing the first and second risk factors, and wherein blocking the distribution of data comprises blocking the distribution of data if the sum including the first and second risk factors exceeds the threshold.
