Since the common Web network security access control system cannot reduce the average response time and the average login time as the number of concurrent users increases,a Web network security access control system based on big data was designed. The hardware design of the system was accomplished by means of the design of three-level security Web network architecture,PKI/CA module in big data environment,and network security isolation module. The software design of the system was accomplished by means of the design of system database,centralized authentication/authorization module,and security ac-cess control server. The experimental results show that the Web network security access control system based on big data can ef-fectively control the average response time and the average login time of users.%普通Web网络安全访问控制系统不能随着并发用户数量的增加而降低平均响应时间和平均登录时间.为了解决此问题,设计基于大数据的Web网络安全访问控制系统.通过Web三级安全网络架构设计、大数据环境下系统PKI/CA模块设计、网络安全隔离模块设计,完成系统硬件设计;通过系统数据库设计、集中认证/授权模块设计、安全访问控制服务器设计,完成系统软件设计.实验结果表明,应用基于大数据的Web网络安全访问控制系统后,用户平均响应时间和平均登录时间得到有效控制.
