Network self-diagnosis control device based on block chain

Abstract

Disclosed is a network self-diagnosis control device based on a block-chain. The device includes a management policy registering unit configured for registering, in a block-chain gateway, an identification code for each of a plurality of network nodes constituting a target network and a management policy indicating a permission range, an operation verifying unit configured for verifying an operation of a specific network node executed by a specific user through the block-chain gateway, and an operation permission determining unit configured for, when the operation of the specific network node is not registered on the block-chain gateway, self-diagnosing management policies of other network nodes of the same type as the specific network node in the block-chain gateway and for determining whether to permit the operation based on the self-diagnosing result.
