1. A computer implemented method comprising: receiving, at a server comprising one or more processing devices, information about multiple assets associated with a network of devices; generating, by the server, for a first asset of the multiple assets, a first security token that is based at least on a portion of the received information about the first asset, wherein the first security token is configured to identify a first home network defined for the first asset, the first home network being specific to the first asset and being defined by a first selection of other assets; generating, by the server, for a second asset of the multiple assets, a second security token that is based at least on a portion of the received information about the second asset, wherein the second security token is configured to identify a second home network defined for the second asset, the second home network being specific to the second asset and being defined by a second selection of other assets; storing, in a storage device communicably coupled with the server, information about the first and second security tokens and information linking the first and second security tokens to the corresponding assets; initiating, by the server, integration of the first and second security tokens with the corresponding assets by providing the first and second security tokens to the corresponding assets; and restricting access, by the server, to the first or second asset upon detecting an occurrence of an unauthorized activity involving the corresponding asset, wherein the server is communicably coupled to the first home network and the second home network, and is configured to detect the occurrence of the unauthorized activity based on information received from the corresponding security token.
