The United States and the European Union this week conducted their first ever exercises to test responses to attacks on critical infrastructure.

"Security experts from the US and 27 EU member states were involved in the drill, which simulated crises affecting national security," writes The Register's Dan Goodin.

"The goal of the operation – which was organized by ENISA, or the European Network and Information Security Agency, and the Department of Homeland Security – was to identify weaknesses in critical infrastructure and learn how security professionals in different countries could rapidly develop an effective response," Goodin writes.
