The Information Technology Sector is central to the nation’s security, economy, and public health and safety. Businesses, governments, academia, and private citizens are increasingly dependent upon Information Technology Sector functions. These virtual and distributed functions produce and provide hardware, software, and information technology systems and services, and – in collaboration with the Communications Sector – the Internet. The sector’s complex and dynamic environment makes identifying threats and assessing vulnerabilities difficult and requires that these tasks be addressed in a collaborative and creative fashion.
Information Technology Sector functions are operated by a combination of entities – often owners and operators and their respective associations – that maintain and reconstitute the network, including the Internet. Although information technology infrastructure has a certain level of inherent resilience, its interdependent and interconnected structure presents challenges as well as opportunities for coordinating public and private sector preparedness and protection activities.
