摘要

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.

說明書

FIG. 1B shows DSDN 100 of FIG. 1 with communication connections for secondary device 104 after device 104 is provisioned into network 100. DSDN 100 provides device 104 with communication to computer 122 of subnetwork 120, to subnetworks 140 and 150, and the internet all via router 106. Secondary device 104 may be, for example, a child who lives in the home in which DSDN 100 in implemented. Because of this, device 104 is not provided access to house hold systems such as the HVAC system supported by subnetwork 130. Furthermore, device 104 is only provided access to computer 122, which may be, for example, the child's computer. It will be understood that DSDN 100 is a dynamic network such that access for device 104 may be changed and that change may be DSDN 100 implemented or may be manually configured by an administrator, for example by the user of primary device 102.
