The CISO for a power plant, utility, responsible for generating electricity, faces some specific challenges that they must address to ensure the security of any critical infrastructure.

Here are some key considerations for Powerplant Cybersecurity and physical security:

Physical Security

Power plants have unique physical security requirements due to the criticality of their infrastructure. Protecting physical assets, such as generators, transformers, and control rooms, is crucial. Implement measures such as surveillance systems, access controls, intrusion detection, and monitoring to prevent unauthorized physical access and tampering.

Supply Chain Security

The power generation industry relies on a complex supply chain, which can introduce security risks. Ensure that your supply chain partners have robust security practices in place. The utility CISO must assess the security posture of vendors, contractors, and suppliers who have access to critical systems or sensitive information. Regularly monitor and review their security controls to mitigate potential risks.

Insider Threats

Insider threats can be a significant concern in power plants. Employees, contractors, or third-party service providers with privileged access can intentionally or unintentionally cause disruptions or compromise systems. The utility CISO has to implement strong access controls, user monitoring, and security awareness programs to detect and prevent insider threats.

Cyber-Physical Risks

Power plants are susceptible to cyber-physical risks, where cyberattacks can directly impact physical infrastructure. For example, attacks targeting industrial control systems can lead to operational disruptions, equipment damage, or safety risks. The utility CISO can implement measures to detect and prevent such risks, such as anomaly detection, incident response plans, and regular security assessments.

Emergency Response Planning

Power plants must have well-defined emergency response plans to address cybersecurity incidents and physical emergencies. Collaborate with relevant stakeholders, such as local authorities, to develop comprehensive plans that cover cyber incidents, natural disasters, or other emergencies. The utility CISO can regularly test and update these plans to ensure their effectiveness.

Regulatory Compliance

The power generation industry is subject to specific regulations and standards, such as the North American Electric Reliability Corporation (NERC) Critical Infrastructure Protection (CIP) standards. The utility CISO must ensure compliance with these regulations and implement security controls accordingly. Regularly assess and report on compliance to regulatory bodies to ensure optimal Powerplant Cybersecurity posture.

Incident Detection and Response

Establish robust systems for monitoring and detecting security incidents in real-time. Implement security information and event management (SIEM) solutions, intrusion detection systems, and log monitoring to detect anomalies and potential attacks. The utility CISO can develop incident response plans to address security incidents promptly and effectively.

Physical and Cyber Security Integration

Power plants must integrate physical and cyber security measures to ensure holistic protection. Collaborate with physical security teams to align security controls and incident response procedures. The utility CISO must consider methods to implement technologies such as video surveillance, access controls, and perimeter protection to monitor physical security alongside cybersecurity measures.

Employee Training and Awareness

Provide comprehensive cybersecurity training and awareness programs to all employees, contractors, and stakeholders. The utility CISO must educate them about the unique risks and responsibilities associated with working in a critical infrastructure environment. How can the utility CISO foster a culture of security awareness to ensure that individuals understand their role in maintaining a secure environment?

By addressing these Powerplant Cybersecurity considerations and staying updated on emerging threats, you can enhance the security posture of your power plant and protect critical infrastructure from cyber threats.

As a CISO in a power plant responsible for generating electricity, there are specific challenges and “gotchas” that you should be aware of to ensure the security of critical infrastructure.

Here are some key considerations for Powerplant CISOs, regarding Operational Technology:

Industrial Control Systems (ICS) Security

Power plants rely on complex industrial control systems to manage and control their operations. These systems are often interconnected and may use legacy technology, making them vulnerable to cyber threats. In addition, the drive to further digitize operations is causing fairly rapid adoption of digital technologies and opening up the OT networks to attack from the Internet. The CISO must ensure that robust security measures, such as network segmentation, intrusion detection systems, and access controls, are implemented to protect their ICS environment.

In 2021, approximately 90 percent of manufacturing organizations had their production or energy supply hit by some form of cyberattack.

Enhancing operational technology (OT)

Enhancing operational technology (OT) cybersecurity is challenging for Powerplant CISOs, as it presents barriers in multiple areas: technical (such as legacy and remote solutions), operational (such as the decisions on which parts of the process the IT and OT teams own), and investment (such as a shortage of the trained skill set). However, (according to McKinsey), as the world is becoming more digital, industrial organizations are making progress in securing OT environments by following three key principles:

• Strengthening technological foundations. Organizations are securing OT environments with proper accesses and standardized controls through today’s technology.
• Assigning clear responsibilities. Clarifying role responsibilities for OT and IT teams, along with external partners, enables a quick response to cyberincidents.
• Increasing risk-aware capabilities and mindsets. By applying the proper incentives, organizations can proactively involve all stakeholders.

Effects of cyberattacks on OT environments

Powerplant CISOs have to watch for OT cyberattacks, that tend to have higher, more negative effects than those in IT do, as they can have physical consequences (for example, shutdowns, outages, leakages, and explosions). Of 64 OT cyberattacks publicly reported in 2021 (an increase of 140 percent over the number reported in 2020), approximately 35 percent had physical consequences, and the estimated damages were $140 million per incident. Geopolitical risks in 2022 resulted in an 87 percent increase in ransomware incidents, with 72 percent of the overall rate increase over the 2021 figures coming from Europe and North America (40 percent more in North America, 32 percent more in Europe, and 28 percent more in other continents, compared with 2021 data).

Cyberattackers often use ransomware and less-secured third-party connections to hijack OT devices, an action that can stop production and operations. Industrial organizations typically face technical and operational challenges, including the following, when trying to protect against such attacks:

• legacy systems, which can be 30 or more years old, with old vulnerabilities and limited security controls (for example, attackers can infect 2008 Windows servers using a specially crafted font to execute malicious code)
• limited ability to implement security controls on legacy OT devices supplied before cybersecurity became an issue and managed by OEMs (for example, sensors installed on valves and connected to a network without internal hardening procedures)
• third-party remote connections to control OT devices connected to an internal network (for example, attackers can strike a vendor-created network and use it to infect other devices)
• unclear ownership between OT and IT teams that makes it difficult to centralize, manage, and govern OT cyber operations (for example, integration of manufacturing execution systems with enterprise resource planning without the introduction of a 3.5 demilitarized zone).
• risk awareness versus risk tolerance leads to competing business priorities for OT decision makers who need to decide between increasing productivity and securing devices (for example, increased production versus patch management that could cause interruption in operations)
• shortage of combined cybersecurity and automation skills with the required cybersecurity and automation-control-system-specific experience (for example, an expert in OT cybersecurity but lacking automation and process expertise)
• business, operational, and technical restrictions that mean a continuous process may run for three years before a planned shutdown, which limits the ability of OT teams to patch devices and implement time-sensitive solutions (for example, stopping an energy supply to update an operational server with a security patch)
