One of the most valuable steps an organization can take is to establish a cyber-threat profile, which is a deep-dive look at your organization's adversaries, vulnerabilities and risk. The creation of a cyber-threat profile should be based on intelligence and due diligence and should be used to drive action for the other cyber-defense functions.
