The United Kingdom has a diverse cyber security community, interconnected in a complex network.

According to a parliamentary committee the UK government is not doing enough to protect the nation against cyber attack.^[1]

• EURIM, the Digital Policy Alliance ^[2]

The UK Government periodically publishes a Cyber Security Strategy.^[3]

Many of the stakeholders across all categories are engaged with that effort.

The overall responsibility for security within the UK rests with the National Security Council which is a cabinet committee chaired by the Prime Minister tasked with overseeing all issues related to national security, intelligence coordination, and defence strategy.

The internal protective security coordination role for UK government is led by the Government Chief Security Officer (GCSO) within the Cabinet Office, who since 2021 has been Vincent Devine.^[4]

The central organisation supporting the GCSO is the Government Security Group (GSG), with a distributed Government Security Function / Government Security Profession across the departments and Arms Length Bodies (ALB), and three National Technical Authorities (NTA), all of which have a role in information and/or cyber security:

• The National Technical Authority for Cyber Security (NTA-C) is the National Cyber Security Centre (NCSC) is the UK's authority on cyber security; its parent organisation is GCHQ. It absorbed and replaced CESG (the information security arm of GCHQ) as well as the Centre for Cyber Assessment (CCA), Computer Emergency Response Team UK (CERT UK) and the cyber-related responsibilities of the former Centre for the Protection of National Infrastructure (CPNI). NCSC provides advice and support for the public and private sector in how to avoid cyber threats.^[5] CESG (originally Communications-Electronics Security Group) was a branch of GCHQ which worked to secure the communications and information systems of the government and critical parts of UK national infrastructure. The NPSA provided protective security advice to businesses and organisations across the national infrastructure.
• The National Technical Authority for Protective Security (NTA-P) is the National Protective Security Authority (NPSA) is the successor organisation to CPNI, but retains some elements of information and cyber security that were not transferred to NCSC, including for Cyber Physical Systems (CPS), and for security containers, locks, and structures to protect assets
• The National Technical Authority for Technical Security (NTA-T) is the UK National Technical Authority for Counter-Eavesdropping (UK NACE), which deals predominantly with countering technical surveillance

The role of Lead Government Department (LGD) for Cyber Security is currently fulfilled by the Department for Science, Innovation, and Technology (DSIT), having previously rested with:

• The Department for Culture, Media, and Sports (DCMS)
• The Department for Business, Energy & Industrial Strategy (BEIS)
• The Department for Business & Industrial Strategy (BIS)
• The Department for Trade and Industry (DTI)

All other government departments and ALBs will have staff in the government security function / government security profession, supporting both their internal staff, and their client communities.

Former bodies in this category include:

• The Office of Cyber Security and Information Assurance (OCSIA) supports the Minister for the Cabinet Office, the Rt Hon Francis Maude MP and the National Security Council in determining priorities in relation to securing cyberspace. The unit provided strategic direction and coordinates action relating to enhancing cyber security and information assurance in the UK. The OCSIA was headed by James Quinault.,^[6] but the function has been subsumed into the Government Security Group.

The Ministry of Defence has primacy for information and cyber security within both its civilian and military staffs (approximately 250,000 personnel), and for the Defence Supply Base (DSB - approximately 30,000 companies).

It has two main security organisations:

• The Directorate of Security and Resilience (DSR), predominantly focused on physical and personnel security
• The Directorate of Cyber Defence and Risk (CyDR), predominantly focused on information and cyber security

These organisation work collaboratively to publish not only the internal rules, but also Defence Standards and Industry Security Notices (ISN)^[7]

In April 2016, the MOD announced the creation of the Cyber Security Operations Centre (CSOC) with a budget of over £40 million. It is located at MoD Corsham.^[8][9]
