"Improving information sharing in the post - September 11 world requires an environment that supports the sharing of information across all levels of government, disciplines, and security domains. As with our achievements to date, an improved information sharing environment will not be constructed overnight, but rather will evolve over time and will be the fruit of careful cultivation. An improved information sharing environment also will be constructed upon a foundation of trusted partnerships among all levels of government, the private sector, and our foreign allies-partnerships based on a shared commitment to detect, prevent, disrupt, preempt, and mitigate the effects of terrorism. This Strategy sets forth the Administration's vision of what improvements are needed and how they can be achieved. "The Strategy was developed with the understanding that homeland security information, terrorism information, and law enforcement information related to terrorism can come from multiple sources, all levels of government, as well as from private sector organizations and foreign sources. Federal, State, local, and tribal government organizations use such information for multiple purposes. In addition to traditional law enforcement uses, such information is used to (1) support efforts to prevent terrorist attacks, (2) develop critical infrastructure protection and resilience plans, (3) prioritize emergency management, response, and recovery planning activities, (4) devise training and exercise programs, and (5) determine the allocation of funding and other resources for homeland security-related purposes".
