Pipeline bursting, production lines shut down, frenzy traffic, trains confrontation, the nuclear reactor shut down, disrupted electric supply, interrupted oxygen supply in ICU – these catastrophic events could result because of an erroneous SCADA system/ Industrial Control System (ICS). SCADA systems have become an essential part of automated control and monitoring of Critical Infrastructures (CI). Modern SCADA systems have evolved from standalone systems into sophisticated, complex, open systems connected to the Internet. This geographically distributed modern SCADA system is more vulnerable to threats and cyber attacks than traditional SCADA. Traditional SCADA systems were less exposed to Internet threats as they operated on isolated networks. Over the years, an increase in the number of cyber-attacks against the SCADA systems seeks security researchers’ attention towards their security. In this review paper, we first review the SCADA system architectures and comparative analysis of proposed/implemented communication protocols, followed by attacks on such systems to understand and highlight the evolving security needs for SCADA systems. A short investigation of the current state of intrusion detection techniques in SCADA systems is done, followed by a brief study of testbeds for SCADA systems. The cloud and Internet of things (IoT) based SCADA systems are studied by analyzing modern SCADA systems’ architecture. In the end, the review paper highlights the critical research problems that need to be resolved to close the security gaps in SCADA systems.

SCADA系统的体系结构和安全性:综述

ICU中的管道爆裂,生产线关闭,交通繁忙,火车对抗,核反应堆关闭,电力供应中断,氧气供应中断–这些灾难性事件可能是由于错误的SCADA系统/工业控制系统(ICS)导致的。SCADA系统已成为关键基础结构(CI)自动化控制和监视的重要组成部分。现代SCADA系统已经从独立系统演变为连接到Internet的复杂,复杂,开放的系统。与传统的SCADA相比,这种地理上分散的现代SCADA系统更容易受到威胁和网络攻击。传统的SCADA系统在隔离的网络上运行,因此较少受到Internet威胁。这些年来,针对SCADA系统的网络攻击数量的增加,吸引了安全研究人员对其安全性的关注。在本文中,我们首先回顾了SCADA系统体系结构,并对提议/实现的通信协议进行了比较分析,然后对此类系统进行了攻击,以了解和突出SCADA系统不断发展的安全需求。对SCADA系统中入侵检测技术的当前状态进行了简短的调查,然后对SCADA系统的测试平台进行了简要研究。通过分析现代SCADA系统的体系结构,研究了基于云和物联网(IoT)的SCADA系统。最后,这篇综述文章重点介绍了需要解决的关键研究问题,以弥合SCADA系统中的安全漏洞。在本文中,我们首先回顾了SCADA系统体系结构,并对提议/实现的通信协议进行了比较分析,然后对此类系统进行了攻击,以了解和突出SCADA系统不断发展的安全需求。对SCADA系统中入侵检测技术的当前状态进行了简短的调查,然后对SCADA系统的测试平台进行了简要研究。通过分析现代SCADA系统的体系结构,研究了基于云和物联网(IoT)的SCADA系统。最后,这篇综述文章重点介绍了需要解决的关键研究问题,以弥合SCADA系统中的安全漏洞。在本文中,我们首先回顾了SCADA系统体系结构,并对提议/实现的通信协议进行了比较分析,然后对此类系统进行了攻击,以了解和突出SCADA系统不断发展的安全需求。对SCADA系统中入侵检测技术的当前状态进行了简短的调查,然后对SCADA系统的测试平台进行了简要研究。通过分析现代SCADA系统的体系结构,研究了基于云和物联网(IoT)的SCADA系统。最后,这篇综述文章重点介绍了需要解决的关键研究问题,以弥合SCADA系统中的安全漏洞。其次是对此类系统的攻击,以了解和突出SCADA系统不断发展的安全需求。对SCADA系统中入侵检测技术的当前状态进行了简短的调查,然后对SCADA系统的测试平台进行了简要研究。通过分析现代SCADA系统的体系结构,研究了基于云和物联网(IoT)的SCADA系统。最后,这篇综述文章重点介绍了需要解决的关键研究问题,以弥合SCADA系统中的安全漏洞。其次是对此类系统的攻击,以了解和突出SCADA系统不断发展的安全需求。对SCADA系统中入侵检测技术的当前状态进行了简短的调查,然后对SCADA系统的测试平台进行了简要研究。通过分析现代SCADA系统的体系结构,研究了基于云和物联网(IoT)的SCADA系统。最后,这篇综述文章重点介绍了需要解决的关键研究问题,以弥合SCADA系统中的安全漏洞。通过分析现代SCADA系统的体系结构,研究了基于云和物联网(IoT)的SCADA系统。最后,这篇综述文章重点介绍了需要解决的关键研究问题,以弥合SCADA系统中的安全漏洞。通过分析现代SCADA系统的体系结构,研究了基于云和物联网(IoT)的SCADA系统。最后,这篇综述文章重点介绍了需要解决的关键研究问题,以弥合SCADA系统中的安全漏洞。
