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

Although the terminology is currently largely aligned to a "cyber" view of the world, it is taken to still include information-related concerns, with previous predominant terminology including:

• Automated Data Processing Security or ADP Security (1980s)
• Computer Security or CompuSec (early 1990s)
• IT Security or ITSec (mid 1990s)
• Information Security or InfoSec (late 1990s and early 2000s)
• Information Assurance or IA (2000s and early 2010s)

The significant constituents within that community are probably best understood by grouping into high level categories, namely:

• Public sector bodies
• Academia
• Professional bodies
• Industry groups
• Cross-sector bodies

Public sector bodies

Legislative

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]

Central government

National strategy

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

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

Capstone components

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

Coordination of activity across government is through a series of committees, both from within the world of security,^[6] and in aligned domains such as the Chief Technology Officers (CTO), and Knowledge and Information Management (KIM).

Civilian components

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)

DSIT is responsible for supporting and promoting the UK cyber security sector, promoting cyber security research and innovation, and working with the National Cyber Security Centre to help ensure all UK organisations are secure online and resilient to cyber threats.

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.,^[7] but the function has been subsumed into the Government Security Group.

Defence components

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)^[8]

In April 2016, the MOD announced the creation of the Cyber Security Operations Centre (CSOC) "to protect the MOD's cyberspace from malicious actors" with a budget of over £40 million. It is located at MoD Corsham.^[9][10]

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

• Defence Cyber Protection Partnership (DCPP)^[11]
• Defence Industrial Security Association (DISA),^[12] formerly the Guild of Security Controllers (GSC)
• Team Defence Information (the current operating name for the UK Council for Electronic Business (UKCeB)), which is a not-for-profit, membership organisation whose mission is to transform secure information sharing for through life collaboration in defence acquisition and support.^[13]

Former bodies in this category include:

• DIPCOG, the Defence Infosec Product Co-Operation Group

National Cyber Force (NCF)

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

Law Enforcement

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)

Wider Public Sector

The Wider Public Sector (WPS) covers both the Central Government and Law Enforcement categories that are itemised separately, but also elements such as:

• Education
• Health
• Local Authorities

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),^[14] formerly the Public Sector IA Coordination Group (PSIACG)
• Cyber Aware is a cross-government awareness and behaviour campaign which provides advice on the simple measures individuals can take to protect themselves from cyber crime.

Former bodies in this category include:

• CIPCOG, the Civil Infosec Product Co-Operation Group

Regulatory bodies

Two regulatory bodies have a specific cyber security related function:

• The Information Commissioner's Office (ICO),^[15] 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.

Academia

Work in academia on information and cyber security can be delineated into research and teaching.
