Abstract: | ABSTRACT Information sharing and collaboration on critical infrastructure protection efforts are major drivers of interest for national security, law enforcement, first responders, and environmental regulators. Critical infrastructure protection information, as stated in the U.S. Patriot Act, are “systems and assets, whether physical or virtual, so vital to the United States that the incapacity or destruction of such systems and assets would have a debilitating impact on security, national economic security, national public health, or any combination of those matters.” Due to the unique, blended nature among customers, suppliers, and contractors within the aerospace and defense industry, a secure method for collaboration is a critical issue that requires remediation. |
