Abstract

When deploying database-centric web applications, administrators should pay special attention to database security requirements. Acknowledging this, Database Management Systems DBMS implement several security mechanisms that help Database Administrators DBAs making their installations secure. However, different software products offer different sets of mechanisms, making the task of selecting the adequate package for a given installation quite hard. This paper proposes a methodology for detecting database security gaps. This methodology is based on a comprehensive list of security mechanisms derived from widely accepted security best practices, which was used to perform a gap analysis of the security features of seven software packages composed by widely used products, including four DBMS engines and two Operating Systems OS. The goal is to understand how much each software package helps developers and administrators to actually accomplish the security tasks that are expected from them. Results show that while there is a common set of security mechanisms that is implemented by most packages, there is another set of security tasks that have no support at all in any of the packages.

数据库中的安全漏洞:Web应用程序支持的替代软件产品的比较
在部署以数据库为中心的web应用程序时,管理员应特别注意数据库的安全要求。认识到这一点,数据库管理系统DBMS实现了几种安全机制,帮助数据库管理员dba确保其安装的安全性。然而,不同的软件产品提供不同的机制集,使得为给定的安装选择适当的软件包的任务相当困难。本文提出了一种检测数据库安全漏洞的方法。该方法基于广泛接受的安全最佳实践衍生的安全机制的综合列表,该列表用于对由广泛使用的产品(包括四个DBMS引擎和两个操作系统OS)组成的七个软件包的安全特性进行差距分析。目标是了解每个软件包在多大程度上帮助开发人员和管理员实际完成了期望他们完成的安全任务。结果表明,虽然存在一组由大多数包实现的通用安全机制,但存在另一组在任何包中都完全不支持的安全任务。
