Leakage Prevention Method for Structured Data Based on Hierarchical Classification

摘要

As the phenomenon of users with low security classification to access to sensitive data of high-level is likely to occur during the access to sensitive information in structured data, resulting in leakage of corporate information assets, and causing serious losses to enterprises, in this paper, a new leakage prevention method is proposed for structured data in which an anti-leakage strategy with appropriate granularity is developed to achieve structured data leakage prevention based on hierarchical classification of data, effectively solving the problem of leakage of corporate information assets; meanwhile highly sensitive data, sensitive data and internal data containing sensitive information are encrypted to further protect the security of their storage and access.
