Abstract

Cyber security in the banking sector is of high importance nowadays. The rate of cyberattacks is spiking every year, and the implementation of strong cybersecurity models is required to ensure the confidentiality and integrity of data. Since protecting a bank requires a wide range of security practices, this paper focuses on protecting the bank resources from malicious actors and securing the transactions using a blockchain consensus mechanism that uses a zero-trust security approach among the participants in the transaction. In addition to the framework, an algorithm for blockchain-based online transactions was designed to make use of practical implementation in the future. The ideas formulated during the research and literature review were integrated to design the framework and the algorithm. The proposed framework ensures that the security of the banking sector can be enhanced by adopting the zero-trust concept and blockchain technology. The consensus algorithms used for the transaction make it immutable and decentralized. Zero-trust principles adopted in the model ensure the confidentiality and integrity of the banking system.

针对银行业数据泄露的零信任安全模型:区块链共识算法
如今,银行业的网络安全具有高度重要性。网络攻击的发生率每年都在飙升,需要实施强有力的网络安全模型来确保数据的机密性和完整性。由于保护银行需要广泛的安全实践,本文侧重于保护银行资源免受恶意行为者的攻击,并使用区块链共识机制保护交易安全,该机制在交易参与者之间使用零信任安全方法。除了该框架外,还设计了一种基于区块链的在线交易算法,以利用未来的实际实施。将研究过程中提出的思想和文献综述相结合,设计了框架和算法。拟议的框架确保通过采用零信任概念和区块链技术来增强银行业的安全性。用于事务的一致性算法使其不可变且去中心化。该模型采用的零信任原则确保了银行系统的机密性和完整性。
