OT security is a vital part of any organization’s cybersecurity infrastructure. Breaches can have serious consequences, including operational disruptions, financial losses, and compromise of sensitive data.
Some of the most essential OT security trends and solutions for 2024 will be discussed in this post. The need for OT security solutions is growing, the first trend.
The Increasing Convergence of IT and OT
With IT and OT converging, the air gap that once separated them rapidly disappears. This convergence enables organizations to optimize business processes by integrating them with more OT devices and systems. But, the convergence also increases the number of gateways into their network, making the attack surface much more significant.
IT and OT were historically separate and managed by different teams with priorities and security concerns. For example, IT security prioritizes data confidentiality, integrity, and availability, while OT focuses on safe equipment operation in a physical environment. However, as OT and IT environments have become more integrated with the advent of the Internet of Things (IoT) and industrial control systems (ICS), the security gap has widened, and OT has been exposed to the same threat landscape as IT.
The convergence of IT and OT systems has created a new battleground for cybercriminals, putting critical infrastructure at risk. Hackers are increasingly targeting operational technology (OT) assets directly to disrupt operations and indirectly cause financial losses through connected IT systems. From wind turbines and hospital diagnostics to transportation controls and essential infrastructure like traffic lights and water management, the potential for real-world emergencies like power outages and water contamination is no longer confined to the realm of fiction. Securing operational technology from cyberattacks is no longer a luxury but a vital necessity to protect our critical infrastructure and ensure public safety.
The Evolving Threat Landscape
The topic of OT cybersecurity is expanding and includes both software and hardware technologies used for controlling and monitoring real-world industrial operations. These specialized systems are interconnected with IT networks to deliver greater efficiency and enable innovation. However, these integrations present a unique threat surface actively targeted by malicious actors.
Unlike IT environments, OT cybersecurity is more sensitive to the impact of cyberattacks. This is because OT systems power critical infrastructure, such as electricity, oil, and water. Attacks against these industries have significant consequences ranging from service disruptions to financial repercussions and even potential harm to human life. Recent high-profile attacks, including the Colonial Pipeline ransomware attack and the water treatment plant breach in Oldsmar, Florida, have increased awareness of the need to safeguard OT systems.
As a result, many security leaders are adopting strategies that shift from detection to prevention. This approach ensures OT systems can be assessed and protected without disrupting operations. It also reduces false positive errors that could interrupt normal operations caused by OT cybersecurity tools.
Another emerging concern is the rise of malicious artificial intelligence (AI) systems used for destructive attacks. These include large language models and AI systems trained on massive data to generate human-quality text and translate languages. These systems can be used for various purposes, from developing fake news and conducting disinformation campaigns to cyberattacks.
The Growing Need for Resilience
A growing need for resilience in the field drives the rapid growth of the operational technology security market. This is because OT environments are prone to cyberattacks and have specific production and safety standards that must be met. Hence, ensuring that OT systems are protected against potential threats requires tailored solutions specifically designed for them.
Moreover, businesses’ increasing adoption of OT security solutions further fuels the market’s growth. This is because these solutions can safeguard end-users from various cyberattacks and maintain business continuity in the event of an attack. They also help enterprises comply with strict regulatory policies and industry norms.
This is especially important for the financial sector, where operational resilience is critical. As such, financial institutions are increasingly investing in robust OT security measures. This is because the security of OT systems is essential for maintaining the financial sector’s stability.
Furthermore, the increased investments in OT security by governments worldwide are another major factor driving the growth of the global operational technology security market. This is because it helps in protecting critical infrastructure and other critical services from cyberattacks. Moreover, it helps improve operational efficiency and maintain high safety standards in the industry.
The Importance of Education
As the convergence of IT and OT continues to accelerate, security teams must have the tools to protect these systems. But there’s no one-size-fits-all approach to OT security, and it’s essential to recognize these systems’ unique challenges.
Unlike information technology (IT), where cybersecurity is focused on safeguarding data, operational technology prioritizes safety and availability, as a failure in these systems could result in physical danger. This makes integrating traditional cybersecurity controls into OT environments difficult, and this challenge will only increase as these environments become more complex and interconnected.
The growing emphasis on cybersecurity has also helped develop solutions that enable secure OT infrastructure. These comprise an extensive array of goods and services offering insight into OT networks and a range of instruments to counteract particular risks. The increasing prevalence of these technologies and the increased number of attacks targeting OT systems have created a strong market demand for OT security solutions.
As organizations move to a more risk-based model, they must recognize the need to expand their security operations capabilities. However, the lack of skilled cybersecurity professionals makes this challenging, as the average security job takes 20% longer than other IT positions.
