THE BASICS OF CREATING SECURE DATA ARCHITECTURES FOR FINANCIAL ORGANIZATIONS

The article discusses approaches to the development of systems that minimize the risks of unauthorized access, leaks, and data integrity violations. Special attention is paid to the introduction of security mechanisms at the design stage, the adaptation of architectural models to the conditions of the digital economy, and the use of modern technologies. Due to increased cyber threats and changes in the norms that determine the need to create secure data architectures in financial organizations. The work is based on the concepts of Privacy by Design and security by Design, as well as technological solutions, including blockchain, and adaptive authentication. The approaches presented in the article include micro-segmentation of networks to isolate components, restriction of user privileges, and the use of cryptographic methods to protect information. These measures ensure compliance with the requirements of the digital environment. Scientific articles by foreign authors, as well as materials that are publicly available on the Internet, were used as sources. The information presented in the article is intended for professionals involved in information security, system architecture development, and project management in the financial sector. They will also be useful to other scientific specialists. The focus of the work is on the need for an integrated approach, updating solutions in response to modern threats.
