1. A method of monitoring activity of devices in a network, the method comprising:
using a number of processors to perform the steps of:
passively collecting data regarding how the devices access the network;
for each device on the network, identifying all other devices on the network with which the device communicates;
identifying all communication traffic from the devices to outside the network;
determining if there any required updates for the devices;
determining a number of risk indicators for privacy risks according to device communication within the network, device communication to outside the network, and the required updates for the devices; and
displaying a visualization of any identified risk factors to a user through a user interface,
wherein determining the risk indicators comprises:
creating a model of the network;
testing the model for accuracy;
evaluating, with the model, system level security compliance of the network;
simulating, with the model, effects on the network of a number of different device failures; and
simulating, with the model, effects on the network of a number of different configuration changes.
