The cyber infrastructure includes electronic information and communications systems and services and the information contained in these systems and services. Information and communications systems and services are composed of all hardware and software that process, store, and communicate information, or any combination of all of these elements. Processing includes the creation, access, modification, and destruction of information. Storage includes paper, magnetic, electronic, and all other media types. Communications include sharing and distribution of information. For example: computer systems; control systems (e.g., SCADA); networks, such as the Internet; and cyber services (e.g., managed security services) are part of cyber infrastructure:
- Producers and providers of cyber infrastructure and services represent the information technology industrial base and make up the Information Technology Sector. The producers and providers of cyber infrastructure and services play a key role in developing secure and reliable products and services.
- Consumers of cyber infrastructure must maintain its security as new vulnerabilities are identified and the threat environment evolves. Individuals, whether private citizens or employees with cyber systems administration responsibility, play a significant role in managing the security of computer systems to ensure that they are not used to enable attacks against CIKR.
