Cooperation between the GC and CISO is critical to an organization’s cybersecurity and data privacy efforts. Drawing on their expertise and experience, counsel and CISOs at Lockheed Martin Corporation and Groupon explored how to foster collaboration between those functions, including by team-building, effective reporting lines, proper escalation of issues, information sharing and physical security, at a recent Georgetown Cybersecurity Law Institute conference.
