Ahmik Hindman, senior networks and security consultant at Rockwell Automation, recently spoke to Senior Contributing Technical Editor Wayne Labs about assessing cybersecurity risks, implementing security patches and building a cybersecurity risk management system.

What is a systematic way of accounting for all network and subnetwork nodes and the equipment attached to them?
