SCADA (supervisory control and data acquisition) is a category of software applications for controlling industrial processes, which is the gathering of data in real-time from remote locations in order to control equipment and conditions.
SCADA systems are used by industrial organizations and companies in the public and private sectors to control and maintain efficiency, distribute data for smarter decisions, and communicate system issues to help mitigate downtime.
A basic SCADA system consists of the following components:
Most SCADA supervisory control systems are now programmed using standard interfaces whenever possible. Most programs are written in C or a derived programming language.
A well-designed Operational Technology (OT) cyber security architecture supports an organization in achieving its goals and strategic objectives while minimizing risk from cyber security threats and vulnerabilities. OT cyber security architecture is a crucial component within an organization’s integrated cyber security strategy which comprises layered defenses such as people, process, and technology.
These technologies are-
Network segmentation is a layer of physical security that cordons off a network from other networks, separating an OT network from an IT network, a guest network from a corporate network or one critical manufacturing network from another.
Vulnerability management is defined as the business process of identifying, prioritizing, remediating, and reporting on software insecurities and misconfigurations of endpoints in Operating Technology (OT) or Industrial Control System (ICS) environments.
There are several reasons industrial systems are vulnerable to attacks in OT environments. The age and sensitivity of systems should be of concern in any OT environment. These systems are comprised of highly complex and segregated technology, machinery, and equipment that are sensitive to external devices.
According to the 2020 Global IoT/ICS Risk Report, 71% of these networks have outdated operating systems that are no longer receiving security updates, 64% are using insecure passwords, and 66% are not updated with the latest antivirus updates. This presents the following problems:
A few important processes that may immediately help you in securing your OT environment include:
NIST's Guide to Industrial Control Systems (ICS) Security helps the industry strengthen the cybersecurity of its computer-controlled systems.
Security researchers have revealed that the Indian manufacturing industry is currently facing severe cybersecurity risks. According to a survey from a cybersecurity firm, the manufacturing sector in India accounted for more than 27 percent of the threats detected between January and March 2019.
