The sharing of cyber threat data has garnered national level attention, and improved information sharing has been the objective of several pieces of legislation and two executive orders. Threat sharing is an important tool that might help tilt the field away from adversaries who currently take advantage of the fact that an attack on one organization can be effective against thousands of other organizations over extended periods of time. In the absence of information sharing, critical infrastructure operators find themselves fighting off adversaries individually instead of using the knowledge and experience that already exists in their community. Better threat information sharing is an important goal, but two barriers, one cultural and the other technical, continue to plague well intentioned policy efforts. Failing to meaningfully address both barriers can lead to unnecessary hype and the misappropriation of resources.
