Today, President Biden signed an Executive Order to improve the nation’s cybersecurity and protect federal government networks. Recent cybersecurity incidents such as SolarWinds, Microsoft Exchange, and the Colonial Pipeline incident are a sobering reminder that U.S. public and private sector entities increasingly face sophisticated malicious cyber activity from both nation-state actors and cyber criminals. These incidents share commonalities, including insufficient cybersecurity defenses that leave public and private sector entities more vulnerable to incidents. This Executive Order makes a significant contribution toward modernizing cybersecurity defenses by protecting federal networks, improving information-sharing between the U.S. government and the private sector on cyber issues, and strengthening the United States’ ability to respond to incidents when they occur. It is the first of many ambitious steps the Administration is taking to modernize national cyber defenses. However, the Colonial Pipeline incident is a reminder that federal action alone is not enough. Much of our domestic critical infrastructure is owned and operated by the private sector, and those private sector companies make their own determination regarding cybersecurity investments. We encourage private sector companies to follow the Federal government’s lead and take ambitious measures to augment and align cybersecurity investments with the goal of minimizing future incidents.
