1. A system comprising:
a device within a network of devices, wherein each of the devices comprise a computer processor and memory;
an identifier within the device and having a cryptographic certificate, wherein the device is configured to transmit the identifier to an authenticator as a security proof, and wherein the authenticator comprises a computer processor and memory, wherein the authenticator enables the device to operate on the network subject to a network policy, wherein the network policy disables the device from performing at least one operation within the network before verifying an identity of the device via the identifier and using a distributed ledger; and
a federated learning engine implemented on a plurality of other devices in the network of devices, and in communication with the device, wherein the federated learning engine is configured to determine whether the device is authorized in response to an attempted policy-violative behavior of the device within the network, wherein the federated learning engine is configured to determine whether the device is authorized based on a continuous multi-factor authentication (CMFA) and an activity history of the device within the network.
