基于内容感知的DLP技术分析与研究

电子文件作为信息的主要载体,正广泛应用于各个领域,而电子文件易传播、易扩散的特点,给敏感数据的安全带来严重威胁,如何防止敏感数据泄露,是目前信息安全领域亟待解决的突出难题。文中通过分析敏感数据的查找方法,提出了以内容感知为重点,结合透明加解密的数据泄密防护方案。该方案在防止数据泄露的同时,增强数据的可审计性以及防泄密的适应性,为数据泄密防护的进一步完善提供了依据。

Study and Analysis on DLP Technology based on Content-awareness

As the principal carrier of information,the e-file is widely used in many fields. For its easy propagation and spread,the e-file would bring serious threat to the security of sensitive data. How to prevent data leakage is always a big challenge for information security. Based on analysis of the method for finding sensitive data,a data-loss prevention scheme is proposed,which lays emphasis on the content-awareness and integrates the transparent encryption. It solves the problem of data loss,while enhances the audit ability of data and the adaptability to confidentiality,thus providing a foundation for perfecting data-loss prevention.
