In 1997, the ad hoc Presidential Commission on Critical Infrastructure Protection issued an ominous warning that “the capability to do harm” by “cyberattack” to America’s critical infrastructures “is growing at an alarming rate, and we have little defense against it.” Jones Walker partner Andrew R. Lee argues in this guest article that since then, we have accepted the reality that the threat of critical infrastructure terror attacks is now pervasive, and has also grown increasingly complex and diffuse. He dissects the cybersecurity landscape in the energy industry, explains the effects of regulations and industry initiatives, and shares insights on what is coming from the Trump Administration.
