基于标记和策略管理的数据防泄漏系统设计

随着智能电网的建设不断深入,互动化智能终端设备的大量使用增加了用户侧数据泄漏的风险,同时由于网络通信方式的复杂化和现场操作环境的不可控,使得各类业务数据在传输过程中易造成数据外泄。因此文章结合智能电网数据防泄漏的实际需求,提出了面向智能电网的统一数据防泄漏系统,阐述了该系统的组成、工作流程和部署方式,并借鉴标记的思想,结合策略管理,提出一种基于标记和策略管理的智能电网敏感数据过滤算法,从而为智能电网业务系统敏感数据防护奠定基础。

Design of Data Leakage Prevention System Based on Label and Policy Management

With the development of smart grid, extensive use of the interactive intelligent terminal increases the risk of user-side data leakage. Meanwhile, the complex network communications and uncontrollable operation environment would lead to data leakage in the transmission process. Aiming at this issue, a unifi ed data leakage prevention system for smart grid is presented to meet the requirement of data leakage prevention for smart grid The system structure, working process and deployment is described. Meanwhile, a sensitive data fi ltering algorithm for smart grid based on label and policy management is proposed. This provides the basis of the sensitive data protection for smart grid business system.
