Cybersecurity standards are techniques generally set forth in published materials that attempt to protect the cyber environment of a user or organization. This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services, and systems that can be connected directly or indirectly to networks. The principal objective is to reduce the risks, including prevention or mitigation of cybersecurity attacks. These published materials consist of collections of
  1. tools,
  2. policies,
  3. security safeguards,
  4. guidelines,
  5. risk management approaches,
  6. training,
  7. best practices,
  8. assurance and technologies.
