基于科学计算与数据服务的Linux安全

The Linux Security Based on Science Computing and Data Service

为便于分析科学计算与数据平台的安全隐患,制定安全策略,将操作系统Linux和应用服务的安全简化为内核安全、与网络无关的系统安全、与网络有关的系统安全、与应用有关的系统安全四层分析模型,分析了不同层面Linux的安全隐患,提出了防范措施。并利用此分析模型,给出了基于互联网络环境,建立在Linux操作系统之上的科学计算与数据服务系统的安全策略。

Based on application needs,for easy to analyze the security issue and make security strategy of computing and data platform,this paper simplified Linux and application service＇s security analysis to a four-tier analysis model including kernel security,network-irrelative system security,network-relative system security and application-relative system security.The security troubles of Linux and corresponding treat with means of each tier are discussed,and on the Internet environment,a reliable security strategy of scientific computing and data service system based on Linux OS are established by using four-tier analysis model.
