Abstract
Dynamic Software Defined Networking (DSDN) systems and methods provide secure and isolated subnetworks within a larger network. Each subnetwork may be formed with varied policies and communication restrictions based on at least device type, device grouping, and risk level. The DSDN systems and methods may also be applied to form a network, with or without subnetworks, of devices that are spatially separated, thereby reducing the attack surface of the DSDN-formed network.
Claims20
A communication system, comprising:
- a software defined network (SDN) including a first subnetwork, and a second subnetwork different from the first subnetwork;
- and
- an SDN router configured to (i) operably communicate with a first device, a second device, and a third device, (ii) determine a first risk level for the first device, a second risk level for the second device, and a third risk level for the third device, (iii) provision the first device to access the SDN through the first subnetwork based on the first risk level, (iv) provision the second device to access the SDN through the second subnetwork based on the second risk level, and (v) prevent the third device from accessing the SDN based on the third risk level,
- wherein the first risk level is different from the second risk level, and the third risk level is different from the first and second risk levels.
