Dynamic data leakage prevention system and method

Abstract

The invention discloses a dynamic data leakage prevention system and method. The method comprises a data filtering rule file storage module, a data management control policy storage module and a file scanning engine, wherein the data filtering rule file storage module is used for storing a data filtering file, and the data filtering rule file comprises a plurality of different types of data filtering rules; the data management control policy storage module is used for storing a data management control policy, and the data management control policy comprises corresponding relationships between the different types of data filtering rules and different levels of data management control schemes; and the file scanning engine loads the data filtering rule file and the data management control policy, scans data sent to outside according to the data filtering rule file when the data needs to be sent to the outside, and performs corresponding outside sending control on the data sent to the outside. According to the system and the method, data leakage prevention can be dynamically performed, a leakage prevention management control object is defined in data, and a terminal or a user is no longer taken as a subject, so that the flexibility and security of data security control are improved.

Description

technical field [0001] The invention relates to the field of data security, in particular to a data dynamic leakage prevention system and method. Background technique [0002] In the current information age, the issues of data security and information security are becoming more and more important, and static and passive data leakage prevention can no longer cope with the endless leakage methods. In this regard, Beijing Mingchao Wanda Technology Co., Ltd. proposed and implemented an improvement plan for dynamic data leakage prevention based on keywords, regular expressions and machine learning technology. [0003] At present, the industry generally adopts the traditional static method of controlling outgoing terminals or users to prevent data leakage. However, the emerging methods of using regular expressions, keywords, and machine learning technologies to scan files for encrypted protection still belong to the category of static protection. [0004] The current anti-leakag...
