What is Operational Technology (OT) Cybersecurity?
OT cybersecurity refers to the measures and protocols used to protect hardware and software systems that monitor and control physical processes in industrial environments. This includes systems like Industrial Control Systems (ICS), Supervisory Control and Data Acquisition (SCADA) systems, and other critical infrastructure components. OT cybersecurity aims to safeguard these systems from cyberattacks that could disrupt operations, cause physical damage, or endanger public safety.
In this environment, Privileged Access Management (PAM) plays a crucial role in ensuring that only authorized personnel can access critical control systems. This helps to reduce the risk of malicious activities, human error, and cyberattacks. By implementing PAM, organizations can safeguard their OT assets, maintain operational integrity, and comply with regulatory requirements, all while minimizing the potential impact of security breaches.
Why is OT Cybersecurity important?
As the connectivity between IT and OT environments increases, the potential for cyber threats targeting industrial systems grows. Securing OT environments is crucial to prevent disruptions in critical infrastructure such as power plants, transportation networks, and water treatment facilities. Effective OT cybersecurity helps ensure the continuous and safe operation of these essential services, protect against financial loss, and mitigate risks to public health and safety.
What are the main threats to OT Cybersecurity?
- Direct Attacks: Cybercriminals can directly target OT systems to disrupt operations or cause physical damage. Examples include inserting malicious code into control systems to alter their functionality.
- Indirect Attacks: These attacks start in IT systems and move laterally into OT environments. For instance, ransomware attacks on corporate IT networks can extend to connected OT systems.
- Supply Chain Attacks: Attackers compromise third-party software or service providers to gain access to OT systems. This includes injecting malicious code into software updates or exploiting service providers' privileged access to client networks.
- Social Engineering and Credential Theft: Attackers use phishing and other tactics to steal credentials, which are then used to infiltrate OT systems.
- Ransomware: A significant threat, ransomware attacks can lock down critical OT systems, and then demand payment to restore normal operations.
Securing OT environments involves implementing robust cybersecurity practices, continuously monitoring for threats, and adhering to industry standards and regulations to mitigate these risks.
