Information Technology Sector: Critical Infrastructure and Key Resources

Sector Overview

The Information Technology (IT) Sector has a key role in securing the nation's cyberspace. The IT Sector is composed of entities - owners and operators and their respective associations - who produce and provide hardware, software, and IT systems and services, including development, integration, operations, communications, and security.

The IT Sector is comprised of, but not limited to, the following:

• Domain Name System root and Generic Top-Level Domain operators;
• Internet Service Providers;
• internet backbone providers;
• internet portal and e-mail providers; networking hardware companies; and
• other hardware manufacturers, software companies, security services vendors, communications companies that characterize themselves as having an IT role, edge and core service providers, and IT systems integrators 1.

In addition, federal, state, and local governments participate in the IT Sector as providers of government IT services that are designed to meet the needs of citizens, businesses, and employees.

Recognizing that there is a technological and industry trend toward convergence and because of the interdependent nature of IT and telecommunications, IT Sector efforts are being closely coordinated with the activities of the Communications Sector.
