Security management for net worked client devices using a distributed ledger service

A method for managing a plurality of network-enabled devices, comprising:

• maintaining, by a distributed ledger computing system, a distributed ledger for storing security-related information for a plurality of network-enabled devices;
• a proxy computing system exchanging security-related messages with a plurality of network-enabled devices over a first communication path;
• the proxy computing system transmitting, over a different second communication path and on behalf of the plurality of network-enabled devices, transactions or calls of functions for a distributed ledger storing security-related information for the plurality of network-enabled devices,
• wherein the distributed ledger computing system comprises a repository storing a copy of the distributed ledger, the copy of the distributed ledger being updated when a change is made to the distributed ledger, the method further comprising:
• the proxy computing system accessing the copy of the distributed ledger over a third communication path distinct from the second communication path;
• the proxy computing system receiving, from a network-enabled device of the plurality of network-enabled devices over the first communication path, a security-related request;
• the proxy computing system generating a transaction or a function call for the distributed ledger, the transaction including a unique identifier of the network-enabled device;
• the proxy computing system transmitting the transaction or function call to the distributed ledger computing system for execution on the distributed ledger over the second communication path;
• and
• the proxy computing system retrieving, from the copy of the distributed ledger over the third communication path, security-related information for transmission to the network-enabled device of the plurality of network-enabled devices in response to the security-related request.
