通过分析以主机为管理对象的涉密信息保护技术的特点,提出了一种基于隔离区的信息保护模型.该模型在保证涉密信息可用性不受影响的同时,加强了对涉密信息的保护.实现该模型的关键在于实现进程资源访问的隔离,通过分析Windows操作系统中进程信息可能的泄漏点,结合过滤驱动和程序组件校验的机制构造了涉密信息隔离区来实现进程资源访问的隔离. 相似文献

建立电力二次系统防病毒中心 总被引:1,自引:0,他引:1
根据国家二次系统安全防护要求,电力二次系统必须将所有重要业务与信息系统隔离,同时必须部署一套防病毒中心,以确保二次系统不受病毒侵害,保证安全、稳定运行.根据二次系统安全防护总体要求,从防病毒服务中心部署的角度出发,明确了防病毒服务器的分层部署原则,根据网络拓扑结构,提出在安全Ⅰ、Ⅱ区内,专门开辟一个VPN通道,将防病毒作为一个业务系统考虑,通过VPN的路由重分布,对安全隔离区内各业务系统网段上的主机进行客户端软件的安装、升级、配置、病毒代码的更新以及一些日常管理工作,形成一个全区域的病毒防护体系. 相似文献

Load forecasting is a critical issue for operational planning as well as grid expansion to ensure an uninterruptable electric power system. Being a small but densely populated country in South Asia, Bangladesh has many isolated places which are not connected to national grid yet. If concern authority opts to expand grid to those areas, they need reliable demand data for designing and dimensioning of different power system entities, e.g., capacity, overhead line capacity, tie line capacity, spinning reserve, load-shedding scheduling, etc., for reliable operation and to prevent possible obligatory redesigning. This paper represents an analysis to forecast the electricity demand of an isolated island in Bangladesh where past history of electrical load demand is not available. The analysis is based on the identification of factors, e.g., population, literacy rate, per capita income, occupation, communication, etc., on which electrical load growth of an area depends. Data has been collected from the targeted isolated area and form a grid connected area which is similar to target area from social and geographical perspective. Weights of those factors on load have been calculated by matrix inversion. Demand of the new area is forecasted using these weights factors by matrix multiplication. 相似文献
