Operational Technology (OT) is the hardware and software that controls and monitors physical devices. OT constantly considers processes rather than specific products. OT is employed not just in manufacturing plants, but also in a variety of other industries such as energy & water suppliers and medical technologies. Industrial control systems (ICS) are crucial components of OT.

What is OT Security?

OT security purpose is to safeguard devices and networks in operational contexts. It encompasses of technology, organizational procedures, and processes targeted at monitoring and securing the systems’ availability and integrity. Its primary goal is to assure fault-free functioning.

OT devices control and monitor industrial processes, including manufacturing, energy distribution, and transportation systems. The seamless integration of these technologies has amplified efficiency and also paved the way to cyber vulnerabilities that cybercriminals can exploit.

However, the same technological advancements have given rise to an alarming vulnerability – unpatched IoT and OT devices becoming liable targets for ICS cyberattacks. These attacks pose a significant threat to critical infra, that urges businesses to quantify the potential risks and implement robust security measures.

Cyberattacks on ICS

The consequences of successful cyberattacks on ICS systems can be catastrophic. ICS that manages critical infra are targets for cybercriminals. Cyber threats range from DDoS attacks, ransomware/malware threats, disrupting operations, causing financial losses, and more. Disrupting ICS systems could lead to extended downtime, compromised safety measures, environmental hazards, and economic losses.

Vulnerabilities that are left unpatched

A significant challenge arises from the tendency to overlook device security like patch management. Many IoT and OT devices operate without regular updates or security patches due to various reasons, including lack of awareness, compatibility issues, or the perceived disruption of critical processes. This creates an environment in which devices are susceptible to known vulnerabilities, making them prime targets for cyberattacks.

Risk Mitigation

Regular Patch Management

Companies must prioritize regular updates and security patches for IoT and OT devices. Collaborative efforts are essential between manufacturers, developers, and users to ensure timely and efficient patch deployment.

Segmentation

Isolating critical infra’s from less secure networks can limit the lateral movement of cyber threats. This approach prevents an attack on one part of the network from spreading to other critical systems.

Network Monitoring

Continuous monitoring of network traffic and anomaly detection can identify suspicious behavior early on, enabling rapid response and mitigation.

Awareness Workshops & Training Sessions

Organizations must invest in cybersecurity training and awareness programs for both IT & Non-IT employees. Educating every employee about their cyber responsibility and potential threats and best cyber standards significantly reduces the risk of a cyberattack from becoming successful.

Compliance Regulations

Organizations must comply with regulations and standards that mandate the security and patch management of IoT and OT devices, ensuring a baseline level of protection.

Wrap Up

Companies must employ IDS/IPS tools to monitor network traffic and identify suspicious activities, allowing for fast responses to potential breaches. Conduct routine security audits and assessments to identify vulnerabilities in ICS systems.
