US 2022/0021653 A1 · NETWORK SECURITY DEVICE

Abstract

An out-of-the-box security device is described for a local network to extend security features offered by a communications network to the local network. Communications of the security device to the network may include a secure, layer 2 or layer 3 communication tunnel established with a security platform of the network. Aspects of the security device, such as a security profile and other security information, may be configured or provided by the security platform via the secure tunnel such that installation costs of the device are reduced. Further, the security features of the network may be extended to the local network via the security device for local networks that connect to the network through one or more other networks. Such security features may be provided by the security device at the local network or may be provided by the network based on a flag bit asserted by the security device.

Dependent claims

A device providing security features of a network, the device comprising:

a processing device;
and
a non-transitory computer-readable medium encoded with instructions, when executed by the processing device, cause the processing device to perform the operations of:
receiving, via a layer 2 or layer 3 encryption communication tunnel to a security system of a communication network, a processing rule for transmission of communication packets originating from a local network device, the processing rule associated with a security profile of a local area network;
obtaining a destination address associated with a communication packet received from the local network device;
and
transmitting, based on a comparison of the destination address to the processing rule, the communication packet to an edge device of the communication network.
