摘要
内部网为企事业单位的信息共享提供了便利,但同时也对控制文件输入输出提出了新的挑战。针对涉密内网中文件摆渡带来的安全问题,首先对涉密内网中文件的进出途径以及目前通常的控制措施进行了分析,提出了存在的问题,并进行了相应的安全风险分析。在上述分析的基础上,针对涉密内网中文件的进出控制问题给出了相应的技术与管理措施,提出了基于数字信封的文件输入输出控制系统,在一定程度上增强了涉密内网文件的安全性。
Intranet brought not only the convenience of information sharing for many enterprise and institutions,but also the new challenges towards the file access controlling as the same.Aiming the security issues about secret intranet file ferry,the approach for the secret intranet files and the current control methods were analyzed at first.Then the existing problems were promoted,and the corresponding safety risks were analyzed.Basing above,the technical solution and managing method about secret intranet file access control problems were promoted. Besides,a file in-out control sysytem based on digital envelope. By this means, the security of intranet file would be enhance to a certain extent.
