Internet infrastructure refers to the physical systems that provide internet communication. It include networking cables, cellular towers, servers, internet exchange points, data centers, and individual computers.
Several studies and events have helped to define the scope of critical Internet infrastructure. In August 2013, Internet infrastructure experts including Yuval Shavitt, Bill Woodcock, Rossella Mattioli, Thomas Haeberlen, Ethan Katz-Bassett and Roland Dobbins convened for six days at Schloss Dagstuhl to refine the academic and policy understanding of critical Internet infrastructure, producing a number of papers in the process. [1] In 2017, the Global Commission on the Stability of Cyberspace undertook a global survey of Internet infrastructure experts in order to assess the degree of consensus on what constituted critical Internet infrastructure, producing a Definition of the Public Core which has since been used by the OECD and others as a standardized description of the principal elements of Internet critical infrastructure. [2] [3] In addition to these globally-applicable findings, nationally-specific definitions have been made by individual governments, for example by the US Government Accountability Office in 2006 [4] and the US White House in 2013.

The report of the GCSC Critical Infrastructure Assessment Working Group has summarized the results of their survey in a comprehensive definition of Critical Internet infrastructure, which includes the following elements: [2]
Cyberspace is an interconnected digital environment. It is a type of virtual world popularized with the rise of the Internet. The term entered popular culture from science fiction and the arts but is now used by technology strategists, security professionals, governments, military and industry leaders and entrepreneurs to describe the domain of the global technology environment, commonly defined as standing for the global network of interdependent information technology infrastructures, telecommunications networks and computer processing systems. Others consider cyberspace to be just a notional environment in which communication over computer networks occurs. The word became popular in the 1990s when the use of the Internet, networking, and digital communication were all growing dramatically; the term cyberspace was able to represent the many new ideas and phenomena that were emerging. As a social experience, individuals can interact, exchange ideas, share information, provide social support, conduct business, direct actions, create artistic media, play games, engage in political discussion, and so on, using this global network. Cyberspace users are sometimes referred to as cybernauts.
A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet.
The Internetworking Operating System (IOS) is a family of proprietary network operating systems used on several router and network switch models manufactured by Cisco Systems. The system is a package of routing, switching, internetworking, and telecommunications functions integrated into a multitasking operating system. Although the IOS code base includes a cooperative multitasking kernel, most IOS features have been ported to other kernels, such as Linux and QNX, for use in Cisco products.
Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. Units which are the last receiver or generate data are called hosts, end systems or data terminal equipment.
Internet governance consists of a system of laws, rules, policies and practices that dictate how its board members manage and oversee the affairs of any internet related-regulatory body. This article describes how the Internet was and is currently governed, some inherent controversies, and ongoing debates regarding how and why the Internet should or should not be governed in the future.
A cybersecurity regulation comprises directives that safeguard information technology and computer systems with the purpose of forcing companies and organizations to protect their systems and information from cyberattacks like viruses, worms, Trojan horses, phishing, denial of service (DOS) attacks, unauthorized access and control system attacks. While cybersecurity regulations aim to minimize cyber risks and enhance protection, the uncertainty arising from frequent changes or new regulations can significantly impact organizational response strategies.
Packet Clearing House (PCH) is the international organization responsible for providing operational support and security to critical Internet infrastructure, including Internet exchange points and the core of the Domain Name System. The organization also works in the areas of cybersecurity coordination, regulatory policy and Internet governance.
Bill Woodcock is the executive director of Packet Clearing House, the international organization responsible for providing operational support and security to critical Internet infrastructure, including Internet exchange points and the core of the domain name system; the chairman of the Foundation Council of Quad9; the president of WoodyNet; and the CEO of EcoTruc and EcoRace, companies developing electric vehicle technology for work and motorsport. Bill founded one of the earliest Internet service providers, and is best known for his 1989 development of the anycast routing technique that is now ubiquitous in Internet content distribution networks and the domain name system.
Jeff Moss, also known as Dark Tangent, is an American hacker, computer and internet security expert who founded the Black Hat and DEF CON computer security conferences.
Named Data Networking (NDN) is a proposed Future Internet architecture that seeks to address problems in contemporary internet architectures like IP. NDN has its roots in an earlier project, Content-Centric Networking (CCN), which Van Jacobson first publicly presented in 2006. The NDN project is investigating Jacobson's proposed evolution from today's host-centric network architecture IP to a data-centric network architecture (NDN). The stated goal of this project is that with a conceptually simple shift, far-reaching implications for how people design, develop, deploy, and use networks and applications could be realized.
In routing, the data plane, sometimes called the forwarding plane or user plane, defines the part of the router architecture that decides what to do with packets arriving on an inbound interface. Most commonly, it refers to a table in which the router looks up the destination address of the incoming packet and retrieves the information necessary to determine the path from the receiving element, through the internal forwarding fabric of the router, and to the proper outgoing interface(s).
Marina Kaljurand is an Estonian politician and Member of the European Parliament. Kaljurand served as Minister of Foreign Affairs in Taavi Rõivas' second cabinet as an independent. Earlier, she served as the Ambassador of Estonia to the United States, Russia, Mexico, Canada, Kazakhstan, and Israel.
Proactive cyber defense, means acting in anticipation to oppose an attack through cyber and cognitive domains. Proactive cyber defense can be understood as options between offensive and defensive measures. It includes interdicting, disrupting or deterring an attack or a threat's preparation to attack, either pre-emptively or in self-defence.
A virtual firewall (VF) is a network firewall service or appliance running entirely within a virtualized environment and which provides the usual packet filtering and monitoring provided via a physical network firewall. The VF can be realized as a traditional software firewall on a guest virtual machine already running, a purpose-built virtual security appliance designed with virtual network security in mind, a virtual switch with additional security capabilities, or a managed kernel process running within the host hypervisor.
In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet.
An Internet outage or Internet blackout or Internet shutdown is the complete or partial failure of the internet services. It can occur due to censorship, cyberattacks, disasters, police or security services actions or errors.
Software-defined networking (SDN) is an approach to network management that enables dynamic and programmatically efficient network configuration to improve network performance and monitoring in a manner more akin to cloud computing than to traditional network management. SDN is meant to improve the static architecture of traditional networks and may be employed to centralize network intelligence in one network component by disassociating the forwarding process of network packets from the routing process. The control plane consists of one or more controllers, which are considered the brains of the SDN network, where the whole intelligence is incorporated. However, centralization has certain drawbacks related to security, scalability and elasticity.
The Global Commission on the Stability of Cyberspace was a multistakeholder Internet governance organization, dedicated to the creation of diplomatic norms of governmental non-aggression in cyberspace. It operated for three years, from 2017 through 2019, and produced the diplomatic norm for which it was chartered and seven others.
Operational collaboration is a cyber resilience framework that leverages public-private partnerships to reduce the risk of cyber threats and the impact of cyberattacks on United States cyberspace. This operational collaboration framework for cyber is similar to the Federal Emergency Management Agency (FEMA)'s National Preparedness System which is used to coordinate responses to natural disasters, terrorism, chemical and biological events in the physical world.
Submarine internet cables, also referred to as submarine communications cables or submarine fiber optic cables, connect different locations and data centres to reliably exchange digital information at a high speed.
As input to its process, a working group of the GCSC conducted a broad survey of experts on communications infrastructure and cyber defense to assess which infrastructures were deemed most worthy of protection. On a scale of zero to ten, with zero being 'unworthy of special protection' and ten being 'essential to include in the protected class,' all surveyed categories ranked between 6.02 and 9.01. Accordingly, the Commission defines the phrase 'the public core of the Internet' to include packet routing and forwarding, naming and numbering systems, the cryptographic mechanisms of security and identity, and physical transmission media.
