Distributed ledger for network security management

A security computing device comprising:

• at least one processor;
• and
• memory communicatively coupled to the at least one processor, the memory storing instructions which, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• receiving a communication sent from a first internet-of-things (IoT) device of a plurality of IoT devices communicatively coupled to the security computing device, the communication identifying a first external service to receive the communication;
• accessing a digital certificate associated with the first IoT device from a blockchain network that is accessible by the security computing device, wherein the digital certificate is configured to be used by the security computing device to manage communications between the plurality of IoT devices and a plurality of external services;
• detecting one or more issues relating to power consumption or power distribution of one or more other IoT devices of the plurality of IoT devices to determine whether to send the communication received from the first IoT device to the first external service;
• and
• sending the communication received from the first IoT device to the first external service over a secure connection that is established between the security computing device and the first external service using the digital certificate based at least in part on detection of the one or more issues relating to the power consumption or power distribution of the one or more other IoT devices.

One or more non-transitory computer-readable storage media storing instructions which, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• receiving a communication sent from a first internet-of-things (IoT) device of a plurality of IoT devices communicatively coupled to a security computing device, the communication identifying a first external service to receive the communication;
• accessing a digital certificate associated with the first IoT device from a blockchain network that is accessible by the security computing device, wherein the digital certificate is configured to be used by the security computing device to manage communications between the plurality of IoT devices and a plurality of external services;
• detecting one or more issues relating to power consumption or power distribution of one or more other IoT devices of the plurality of IoT devices to determine whether to send the communication received from the first IoT device to the first external service;
• and
• sending the communication received from the first IoT device to the first external service over a secure connection that is established between the security computing device and the first external service using the digital certificate based at least in part on detection of the one or more issues relating to the power consumption or power distribution of the one or more other IoT devices.
