How it Works

The Hungary Information Self-Determination and Freedom of Information Act — Act CXII of 2011 structures privacy obligations across governance domains and the data processing lifecycle. It outlines data subject rights, transparency duties, and controller/processor responsibilities while prescribing technical and organizational measures as security safeguards. The law emphasizes a risk management approach and retention, access, and accountability requirements aligned with broader privacy principles.

Organizations implement Act CXII by translating statutory requirements into security controls, performing data protection impact assessments, and embedding privacy into vendor and records management. Teams establish policies, appoint responsible roles, conduct compliance assessments and monitoring, and operate incident response and breach notification processes. Continuous auditing and remediation ensure ongoing alignment with governance and compliance obligations.
