The Australian Security Intelligence Organisation is Australia's national security agency responsible for the protection of the country and its citizens from espionage, sabotage, acts of foreign interference, politically motivated violence, attacks on the Australian defence system, and terrorism. ASIO is part of the Australian Intelligence Community and is comparable to the American FBI and the British MI5.
The Security Service, also known as MI5, is the United Kingdom's domestic counter-intelligence and security agency and is part of its intelligence machinery alongside the Secret Intelligence Service (MI6), Government Communications Headquarters (GCHQ), and Defence Intelligence (DI). MI5 is directed by the Joint Intelligence Committee (JIC), and the service is bound by the Security Service Act 1989. The service is directed to protect British parliamentary democracy and economic interests and to counter terrorism and espionage within the United Kingdom (UK).
Counterintelligence (counter-intelligence) or counterespionage (counter-espionage) is any activity aimed at protecting an agency's intelligence program from an opposition's intelligence service. It includes gathering information and conducting activities to prevent espionage, sabotage, assassinations or other intelligence activities conducted by, for, or on behalf of foreign powers, organizations or persons.
Defence Intelligence (DI) is an organisation within the United Kingdom intelligence community which focuses on gathering and analysing military intelligence. It differs from the UK's intelligence agencies in that it is an integral part of a government department – the Ministry of Defence (MoD) – rather than a stand-alone organisation. The organisation employs a mixture of civilian and military staff and is funded within the UK's defence budget. The organisation was formerly known as the Defence Intelligence Staff (DIS), but changed its name in 2009.

The Australian Intelligence Community (AIC) and the National Intelligence Community (NIC) or National Security Community of the Australian Government are the collectives of statutory intelligence agencies, policy departments, and other government agencies concerned with protecting and advancing the national security and national interests of the Commonwealth of Australia. The intelligence and security agencies of the Australian Government have evolved since the Second World War and the Cold War and saw transformation and expansion during the Global War on Terrorism with military deployments in Afghanistan, Iraq and against ISIS in Syria. Key international and national security issues for the Australian Intelligence Community include terrorism and violent extremism, cybersecurity, transnational crime, the rise of China, and Pacific regional security.

The United Kingdom Terror Threat Levels, often referred to as UK Threat Levels, are the alert states that have been in use since 1 August 2006 by the British government to warn of forms of terrorist activity. In September 2010 the threat levels for Northern Ireland-related terrorism were also made available. In July 2019 changes were made to the terrorism threat level system, to reflect the threat posed by all forms of terrorism, irrespective of ideology. There is now a single national threat level describing the threat to the UK, which includes Islamist, Northern Ireland, left-wing and right-wing terrorism. Before 2006, a colour-based alert scheme known as BIKINI state was used. The response indicates how government departments and agencies and their staffs should react to each threat level.

Terrorism in the United Kingdom, according to the Home Office, poses a significant threat to the state. There have been various causes of terrorism in the UK. Before the 2000s, most attacks were linked to the Northern Ireland conflict. In the late 20th century there were also attacks by Islamic terrorist groups. Since 1970, there have been at least 3,395 terrorist-related deaths in the UK, the highest in western Europe. The vast majority of the deaths were linked to the Northern Ireland conflict and happened in Northern Ireland. In mainland Great Britain, there were 430 terrorist-related deaths between 1971 and 2001. Of these, 125 deaths were linked to the Northern Ireland conflict, and 305 deaths were linked to other causes, including 270 in the Lockerbie bombing. Since 2001, there have been almost 100 terrorist-related deaths in Great Britain.

The Government of the United Kingdom maintains several intelligence agencies that deal with secret intelligence. These agencies are responsible for collecting, analysing and exploiting foreign and domestic intelligence, providing military intelligence, and performing espionage and counter-espionage. Their intelligence assessments contribute to the conduct of the foreign relations of the United Kingdom, maintaining the national security of the United Kingdom, military planning, public safety, and law enforcement in the United Kingdom. The four main agencies are the Secret Intelligence Service, the Security Service (MI5), the Government Communications Headquarters (GCHQ) and Defence Intelligence (DI). The agencies are organised under three government departments, the Foreign Office, the Home Office and the Ministry of Defence.
