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]

MOD collaborates with the DSB over information and cyber security matters through a number of organisations, including:

• Defence Cyber Protection Partnership (DCPP)^[10]

Former bodies in this category include:

• DIPCOG, the Defence Infosec Product Co-Operation Group

The National Cyber Force consolidates offensive cyber capabilities from the Ministry of Defence and GCHQ.

The National Crime Agency (NCA) hosts the law enforcement cyber crime unit, incorporating the Child Exploitation and Online Protection Centre.

Former bodies in this category include:

• National High Tech Crime Unit (NHTCU)

Within the WPS, there are a number of collaborative bodies, including:

• Assurance Specialism Advisory Group (ASAG), which runs the SUAC series of Conferences
• Cyber Technical Advisory Group (CTAG),^[11] formerly the Public Sector IA Coordination Group (PSIACG)

Two regulatory bodies have a specific cyber security related function:

• The Information Commissioner's Office (ICO),^[12] leading on Data Protection (DP) for Personally Identifiable Information (PII)
• OFCOM, leading on telecommunications and broadcast aspects of security

Most other regulatory bodies will have staff covering information and cyber security function for both their internal staff, and their client communities.

• Association of Cyber Forensics and Threat Investigators (ACFTI).^[13]
• British Computer Society (BCS) is a professional body and a learned society that represents those working in information technology both in the United Kingdom and internationally. It has a security, data and privacy group.^[14]
• Business Continuity Institute (BCI) was established in 1994 to enable individual members to obtain guidance and support from fellow business continuity practitioners. BCI has a six certification standards to ensure individual practitioners literacy in organizations, responses, and other strategies.^[15]
• Council of Registered Ethical Security Testers (CREST) is a Not for profit accreditation and certification organization.^[16] CREST does not have its own study material and leverage on third party coursework so that the member can become certified. As of 24/8/2022, the cost of CREST membership is 5000GBP for membership of one country chapter and 25000GBP for a regional membership. On two occasions between 2012 and 2014, the examination-related activities of one of more NCC Group employees and candidates breached the CREST Code of Conduct and NCC Group was, as their employer, vicariously responsible for those individuals at the time

In June 2014 the operational authority for Tigerscheme was transferred to USW Commercial Services Ltd.
