Abstract: As one of the most important coal transportation hubs in China, a port has built a highly automated production operation system, realized unmanned operations such as turnover operation and dump operation, and established a production operation control and port information management network, which greatly improved the efficiency of coal dispatch management and port coal throughput. However, under the situation of increasing threats to network security, through the investigation and evaluation of the network security status of production business system, it is found that there are many problems in the security status of the port industrial control network, which makes the production operation system easy to expose to the risk of network attacks. In order to effectively protect the safe operation of the port production business system network, this paper analyses the security loopholes existing in the port production management and control network system according to the characteristics of the port production operation system network, designs the solutions to strengthen the security protection capability of the system, gives the implementation and effect evaluation methods, and summarizes the security protection strategy for production business of the port.

Key words: port production operation, turn-over operation, stockpiling operation, production operation system, network security technology, security protection

摘要： 某港口作为我国重要的煤炭运输枢纽之一，建成了自动化程度较高的生产作业系统，实现了翻场作业、堆场作业等无人化作业，并建成了生产作业控制和港口信息管理网络，极大地提高了煤炭调度管理效率和港口煤炭吞吐量.然而，在网络安全威胁日益增长的背景下，通过对生产业务系统网络安全状况排查和评估，发现该港口工业控制网络安全现状存在很多问题，使生产作业系统容易暴露在网络攻击的风险当中.为了有效保护港口生产业务系统网络的安全运行，针对港口生产业务系统网络的特点，分析了该港口生产管控网络系统存在的安全漏洞，提出了加强系统安全防护能力的解决方案，给出了实施和效果评估方法，并总结了适用于该港口生产业务的安全防护策略.
