the protection of networks and their services from unauthorized modification, destruction, or disclosure. It provides assurance the network performs its critical functions correctly and there are no harmful side effects.[1]

Risks Edit

National security risks have

four basic — vulnerabilities, mitigated by protection measures, and threats, mitigated by deterrents — and each aspect influences the overall risk. Vulnerabilities develop from continuing changes in products, processes, and business practices generally driven by technology development and market forces. Threats are composed of the motivation and capabilities of adversaries. Deterrents are driven primarily by law enforcement capabilities and priorities. Although those responsible for network security have very little, if any, control over these factors, they do have an opportunity to influence one aspect of risk—protection measures.[6]
