Private sector firms have made modest progress in recent years when it comes to adopting cybersecurity best practices, according to Commodity Futures Trading Commission Commissioner Kristin N. Johnson. In remarks delivered last month at the Regulators Roundtable on Financial Markets Innovation and Supervision of Emergent Technology, Johnson discussed international cybersecurity defenses and protocols, and highlighted acute dangers in a heavily interdependent business world where a contagion of breaches, or “domino effect,” is all too likely. This article covers key takeaways from Johnson’s remarks with practical commentary on insider threats, third-party risk mitigation and incident preparation and response from cybersecurity experts at Debevoise & Plimpton and Otterbourg.
