基于云平台的安全审计系统设计与实现

针对云平台日志信息的安全审计及安全存储的需求,提出一种云平台的支持审计信息安全存储的审计系统实现方案.提出的安全审计系统由审计信息记录、审计信息签名、审计信息管理3个功能模块组成,采用Web Services、数字签名等关键技术,实现了对用户信息的获取、分析与数据库存储等功能.另外,系统在实现了网络安全审计的功能基础上,通过对数据库表项信息进行元组签名与分片签名结合的方式,保证了数据的安全与可信.与现有的云平台的安全审计系统实现方案相比,该方案安全性和实用性很高,并具有较好的可移植性.

Design and Realization of Security Audit System based on Cloud Platform

For the requirements of security audit and security storage of log information based on cloud platform, an implementation based on cloud platform and in support of audit information security storage is proposed. Security audit system, composed of audit record module, audit information signature module and audit information management module, uses key technologies including Web Services and digital signature to implement the acquisition, analysis, database storage of user information and other functions. In addition, this system, based on implementation of network security function, can ensure the security and credibility of data by implementing individual signature and group signature. The comparison with existing security audit system implementation based on cloud platform indicates that the proposed implementation scheme has fairly high security and practicability, including fairly good transplantability.
