Industrial Cybersecurity System: Need to Protect Industrial Control Systems Grows

Today, cybersecurity awareness is more critical then ever before for industrial applications. In industrial sectors such as manufacturing, power, transportation, chemicals, and energy/utilities, industrial control systems are used to control physical processes. Industrial control systems include supervisory control and data acquisition (SCADA), distributed control systems (DCSs), programmable logic controllers (PLCs), remote terminal units (RTUs), intelligent electronic devices (IEDs), and other field devices. Nowadays, these systems are increasingly being integrated with network technologies. As a result of the increased connectivity between information technology (IT) and operational technology (OT) environments, industrial control systems have become more prone to intrusions and cyberattacks. Therefore, the need for effective security products and solutions to mitigate these cyber threats has increased in industrial enterprises.

To secure industrial systems from cyberattacks, various solutions and technologies such as distributed denial of service (DDoS), intrusion detection and prevention systems, antivirus, and hardware products, such as gateway and networking devices, are used to ensure the uninterrupted productivity of utilities, grids, transportation systems, and the overall manufacturing sector. Cybersecurity solutions help in strengthening the security of industrial applications by identifying prevailing threats, reducing risks of unauthorized access to critical systems, and enabling secure remote access. Most security product vendors focus on developing products and solutions to secure industrial systems from cyberattacks. The major companies that provide industrial cybersecurity solutions include ABB Ltd. (Switzerland), Honeywell International Inc. (US), International Business Machines Corporation (IBM) Corporation (US), and Cisco Systems Inc. (US).

Industrial Cybersecurity Market (USD Billion)

Industrial Cybersecurity Market (USD Billion)

The industrial cybersecurity market is expected to be worth $22.79 billion by 2023, growing at a compound annual growth rate {CAGR) of 8.6% between 2017 and 2023. The increasing government funding to tackle security breaches and improve industrial cybersecurity, growth in the number of connected devices, and increasing adoption of IoT in industrial control systems are some of the factors driving the market for industrial cybersecurity.

Earlier, the operational technologies of the industrial sectors used to work in isolation. However, with the adoption of Industrial Internet of Things has led to increased connectivity between the information technology (IT) and operational technology (OT), which has exposed operation systems to cyberthreats. The integration of IT and OT has brought security challenges, which in turn have led to growth in the deployment of advanced cybersecurity hardware, software, and services to overcome the prevailing challenges pertaining to cybersecurity. However, the lack of awareness about cybersecurity among employees puts the industrial sector at risk. In addition to implementing appropriate hardware- and software-based protection tools, employee training is also critical to completely secure industrial facilities.

With the increasing incidences of cyber breaches, vendors are focusing on developing advanced hardware with security capabilities. This has also boosted the demand for secure hardware along with software. With the evolution of the automation and IoT ecosystem, companies are developing intelligent gateways, which help in controlling SCADA traffic to prevent cyberattacks on networks and devices by allowing industrial systems to be securely interconnected with management information systems.

 In addition to gateways, the demand for routers and industrial Ethernet switches will continue to proliferate with the increasing cyberattacks, given the growing number of connected and remotely managed industrial systems. Further, between 2017 and 2023, solutions such as firewalls, which block cyberattacks on industrial control systems by filtering the traffic in the network, are also expected to witness a growing demand. The need for firewall solutions to protect critical infrastructure is expected to proliferate owing to the increased sophistication of cyberattacks and security concerns.

Moreover, next-generation firewalls (NGFWs) can monitor industrial protocol traffic and block malicious activities to secure operational technology (OT) environment and have combined capabilities of intrusion prevention and application control. These are expected to have a growing demand in the coming years. The market for identity and access management (IAM) solutions is expected to grow at a high rate between 2017 and 2023. The proliferation of cloud services and mobile devices in industries has necessitated the adoption of access controls. The adoption of cloud and Bring Your Own Device (BYOD) has made it essential for organizations to revise the methods to manage digital identities, thereby boosting the demand for IAM.
