In recent years, there have been several targeted attacks on industrial control systems and systems of critical infrastructure by attackers/malwares with code names such as Stuxnet, Aurora, Flame, and Havex. These were discovered by various security vendors' threat research and intelligence centers. The Internet of Things (IoT) drive has led several industries such as smart manufacturing to adopt and embrace the advantages of connecting to the Internet, thereby unknowingly exposing themselves and becoming more vulnerable to cyber threats. The world has witnessed a number of ICS (industrial control system) attacks in recent times.
Several security breaches events recorded in recent years involving systems of national interest, including both critical infrastructure and government systems, indicate that the global industrial sector is increasingly becoming the target of cyberattacks. As a result, business organizations are making substantial investments in ICS security. The uptake of ICS security solutions has been driven by factors such as increased attacks on critical infrastructure globally, investments in cybersecurity insurance, and investments in Industrial Internet of Things (IIoT) applications. As we move forward, industry-specific regulations and mandates around ICS security will further drive the uptake of these solutions globally.
However, factors such as air gap strategy, security skills shortage and technology sprawl, lack of mandates, and preference for availability over integrity will be major barriers to the growth of this market. The ICS security market is flooded with vendors from various backgrounds. The competitive landscape is comprised of information and communications technology (ICT) vendors, industrial automation vendors, and security vendors offering industrial security solutions. Additionally, the market is poised to witness the participation of service providers offering managed security services through partnerships with various security vendors.
