大型煤化工企业DCS系统网络安全设计
|
摘要
随着计算机和网络技术的发展,DCS系统在稳定性和易用性方面逐步提升,现已广泛应用于工业生产的各个领域,成为大型工业企业的标配。大型煤化工企业普遍存在高温、高压、多有毒可燃气体等特点,不但要保证系统内部数据的稳定传输,更要防范来自外部的黑客及恶意程序攻击。因此,对系统可靠性及网络安全要求更为严格。通过对当前DCS系统网络安全现状分析,结合在大型煤化工企业的网络设计实例,总结提炼出一套行之有效的网络安全设计方案。
With the development of computer and network technology, the stability and usability of DCS system is improved gradually. Currently it has been widely used in every field of industrial production and became a standard application for largescale industrial enterprises. Featured in high-temperature, high-voltage and toxic combustible gas, the coal chemistry enterprises should not only insure stable internal data transmission, but also protect from attack of outside hackers and malwares, so there are strict requirements on system reliability and network safety. The text will analyze network safety condition of current DCS system and summarize a series of practical network safety design proposals based on examples in large-scale coal chemistry enterprises.
