ASSESSMENT OF RISKS AND BENEFITS OF COMBINING ZERO TRUST PRINCIPLES AND BLOCKCHAIN TECHNOLOGY FOR DATA PROTECTION IN MULTI-CLOUD ENVIRONMENTS

The theses present a theoretical and methodological analysis of integrating the Zero Trust model with blockchain technologies as a potential factor for enhancing cybersecurity in multi-cloud environments. Zero Trust serves as a security modernization tool based on strict authentication, minimal access rights, and continuous monitoring. Combining Zero Trust with decentralized blockchain solutions ensures a high level of reliability, transparency, and data immutability. The work analyzes current challenges, advantages, and limitations of this approach, while also highlighting future research prospects. Special attention is given to understanding how these approaches can reduce cyberattack risks, protect important information, and support the development of digital transformation. The theses provide a foundation for further studies in the field of cybersecurity.
