network and information system meaning

What does network and information system mean?
In practice, this term covers: (i) electronic communications networks, (ii) any device or interconnected group of devices that, under a programme, automatically process digital data, and (iii) the digital data those elements store, process, retrieve or transmit for their operation, use, protection and maintenance. It is used to describe the IT, OT and communications infrastructure and the data needed to run and secure it. It is a statutory definition central to cyber security regulation. In the UK, see regulation 1(2) of the Network and Information Systems Regulations 2018, which adopts wording from the NIS framework and cross-refers to an “electronic communications network” within section 32(1) of the communications act 2003. In Ireland, national regulations implementing the EU NIS framework (including NIS2) mirror this definition. Key features and significance: - Broad, technology‑neutral scope covering corporate IT, operational technology, cloud and telecoms infrastructure. - Not limited to personal data; it includes any digital data necessary to operate and protect the system. - Used to determine the scope of NIS/NIS2 security and incident reporting duties for operators of essential services and relevant digital services, and to inform audits, procurement, supply‑chain risk allocation and contractual security clauses. Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland.

EU energy cybersecurity and critical infrastructure: CER, NIS 2, electricity network code, forthcoming gas/hydrogen codes and Cyber Resilience Act—scope, obligations and timelines

Protection of critical infrastructure and cybersecurity—EU strategy In October 2016, the European Parliament’s Committee on Industry, Research and Energy (ITRE) issued a Cybersecurity Strategy for the Energy Sector. The paper reviewed prevailing policies and legislation, and considered routes for developing energy‑specific cyber security solutions and protective practices. It found that the continued rollout of smart energy systems, coupled with growing interconnection and interdependence across Member State borders, has produced rapid expansion of networked intelligence throughout energy grids and into consumers’ premises via smart devices. This enlarged attack surface, together with the fact that the energy system is inherently linked to every other critical infrastructure network, renders the sector especially susceptible to cyber attacks. That exposure has only grown since the 2016 strategy was released. On 16 December 2020, the European Commission and the High Representative of the Union for Foreign Affairs and Security Policy presented a new EU Cybersecurity Strategy. The 2020 plan encompasses the security of essential EU services (for example energy grids, railways and hospitals) and also...

Community energy projects: policy background, subsidy and grant programmes, legal structuring, planning and licensing, grid connections, and proposed mandates on community benefits and shared ownership

What is the policy and legislative background to the support for community energy projects? Legal and policy backing for community energy schemes is comparatively new; although early pledges prompted some movement, progress then remained modest for several years. A concise overview follows. The Community Energy Strategy arose from a 2010 Liberal Democrat manifesto promise to ‘encourage community-owned renewable energy schemes where local people benefit from the power produced’. That pledge appeared, unchanged, in The Coalition: programme for government. In 2014 the then coalition administration, through the former Department of Energy and Climate Change (DECC), issued the UK’s first Community Energy Strategy. DECC then released an update in March 2015. Like the original, the update emphasised enabling localities to make their own advances towards a more decentralised energy system with active community involvement. Further information on the Strategy update is set out in the section: What government policy interventions have been made to support community energy projects? below. DECC later merged with the Department for Business, Innovation and Skills, creating...
