In today’s increasingly interconnected world, Operational Technology (OT) systems have become essential components of critical infrastructure. These systems are responsible for managing and monitoring industrial processes, from power generation and water treatment to manufacturing and transportation. However, as the importance of OT systems grows, so does the risk of security threats. Many organizations focus on implementing robust technical security measures to safeguard their OT environments. Yet, it’s crucial not to overlook the human factor in OT security threats.

Phishing Attacks

One of the most common threats exploiting the human factor is phishing attacks. Cybercriminals use emails, text messages, or phone calls to trick employees into revealing sensitive information. For instance, an attacker might pose as a senior executive, requesting an employee to transfer funds or disclose credentials. Such attacks can lead to unauthorized access, data breaches, and financial losses.

Social Engineering

Social engineering techniques manipulate people into divulging confidential information or performing actions that compromise security. For example, a con artist might impersonate an IT support technician to gain access to a system. Or, they could use pretexting, where they create a false but plausible scenario to obtain information. Effective social engineering attacks can bypass even the strongest technical defenses.

Insider Threats

Another human factor risk is insider threats, where individuals with authorized access to an OT system use it for malicious purposes. This could range from accidentally misconfiguring settings to deliberately stealing data or causing intentional damage. Insider threats can be challenging to detect and mitigate, as they often go unnoticed until significant damage has been done.

Training and Awareness
