摘　　要：针对原有舰船网络访问权限控制软件由于数据处理能力较差,造成权限控制有误差,易造成网络预警有效性较差的问题,设计基于Filter的舰船网络访问权限控制软件。使用数据同步技术,优化网络访问信息数据同步模块,提升软件数据分析能力。设计软件数据库,采用E-R结构与物理结构2种形式,实现软件数据处理能力。在软件中引用网络过滤器,根据访问权限匹配规则树对网络访问信息的计算与匹配,实现对访问信息权限的控制。至此,基于Filter的舰船网络访问权限控制软件设计完成。设定软件应用环节,与原有软件相比,此软件的有效报警次数高于原有软件,由此可知,此软件对于网络中访问的信息过滤与处理能力优于软件,使用此软件可提升舰船网络安全。In view of the problem that the original ship network access control software has poor data processing ability,resulting in the error of access control,which is easy to cause the poor effectiveness of network early warning,a ship network access control software based on filter is designed.Use data synchronization technology to optimize the network access information data synchronization module and improve the software data analysis ability.The software database is designed in the form of E-R structure and physical structure to realize the ability of software data processing.The network filter is referenced in the software,and the access information is calculated and matched according to the access right matching rule tree to control the access information right.At this point,the design of ship network access control software based on filter is completed.Set up the software application link,compared with the original software,the effective alarm times of this software is higher than the original software,so it can be seen that this software is better than the software in filtering and processing information accessed in the network,using this software can improve the ship network security.
