Greetings, friend @mojubare.

I recently made a comment where I raised the usefulness of the IoT in the oil industry. Now I find out this term "IIoT", fascinating !.

One of the advantages that this technology can provide in the industry would be the control of wear or life time of replaceable parts. Maintenance engineering would be enhanced with all the information obtained from the collection of data from the installed sensors. The possibilities are endless.

I agree with you that the system would be very vulnerable. Advanced security protocols should be applied. Firewalls, data encryption, and even blockchain technology.

Your friend, Juan.
