Critical National Infrastructure

Container Networking Interface

Critical National Infrastructure (CNI) refers to the essential systems and assets that are vital for the functioning of a nation, including transportation, energy, healthcare, and communication systems. Protecting CNI is crucial for national security and public safety, as disruptions to these systems can have severe consequences. Governments and organizations implement various measures to enhance the resilience and security of CNI against cyber threats and other risks.

The Container Networking Interface (CNI) is a specification and a set of libraries used for configuring network interfaces in Linux containers. It provides a standardized way for container orchestration systems, like Kubernetes, to manage networking for containers, allowing them to communicate with each other and the outside world. CNI defines how network plugins can be developed, enabling various networking solutions to be easily integrated into containerized environments.

Critical National Infrastructure

[...] are those facilities, systems, sites, information, people, networks and processes, necessary for a country to function and upon which daily life depends. It also includes some functions, sites and organisations which are not critical to the maintenance of essential services, but which need protection due to the potential danger to the public (civil nuclear and chemical sites for example). https://www.cpni.gov.uk/critical-national-infrastructure-0
