Abstract

Systems and methods for establishing a secure communication network are provided. For example, a risk mitigation computing device determine a first set of devices on an enhanced security communication network and a second set of devices on a home communication network. The risk assessment computer system may enable a first network connection between the first set of devices and a cloud-based node via the enhanced security communication network and may enable a second network connection between the second set of devices and an internet. The enhanced security communication network and the home communication network may be separate. The risk mitigation computing device may receive headers of data packets transmitted through the enhanced security communication network and correlate the headers of data packets with risk assessment indicators. The risk mitigation computing device may provide a risk score based on the risk assessment indicators correlated with the headers of data packets.
