Government of Brazil

The Brazilian federal government functions as the central authority responsible for public administration, encompassing the executive, legislative and judicial branches that together formulate and enforce national laws, collect taxes, manage social security programs, deliver public health and education services, oversee infrastructure development and regulate economic activity across the country. It represents Brazil in international relations, negotiates treaties and participates in multilateral organisations while providing consular services to citizens abroad. Through its numerous ministries and agencies, the government issues permits, licenses and certifications that affect businesses, workers and residents, and it maintains civil registries, identification systems and electoral processes that underpin civic life.

The scale of the government’s information handling is evident from several disclosed cyber incidents: in 2023 a breach of the gov.br webmail system exposed 845 MB of personal data including IDs, passport details and medical certificates; in 2022 a ransomware claim asserted the exfiltration of roughly 3 TB of sensitive records such as passports, tax documents and addresses; and in 2020 a leak compromised the personal information of more than 200 000 military personnel and government employees. These episodes illustrate the volume and diversity of data managed by federal, state and municipal administrations, which serve a nationwide population that includes citizens, residents, foreign visitors and enterprises operating within Brazilian territory. The government’s reach extends across all 26 states and the Federal District, with shared service providers supporting multiple municipalities, as seen in the 2023 attack that affected Araguari and nine other localities.

Distinguishing attributes of the organisation include its constitutional supremacy, which grants it the exclusive power to legislate, execute justice and administer public policy, and its regulatory role that spans sectors such as finance, energy, telecommunications, transportation and environmental protection. The government’s notable competencies in managing large‑scale information technology infrastructures are highlighted by the recurring targeting of its online portals, webmail systems and municipal networks, demonstrating both the reliance on digital services and the challenges of securing them. Structurally, the Brazilian federal government is a sovereign entity with no parent organisation or private owners; it is composed of the Presidency, the National Congress and the Federal Judiciary, each operating with defined independence while collaborating to fulfill the state’s mandate. This constitutional framework establishes the government as the primary institution responsible for upholding the rule of law, protecting national sovereignty and providing the public goods and services that underlie Brazilian society.
