The need for cybersecurity controls to protect Operational Technology (OT) systems and physical machines has become increasingly important in various industries. As cybersecurity threats are on the rise, the vulnerability of traditionally isolated Cyber-Physical Systems to cyberattacks has been exposed. Recent incidents such as the Colonial Pipeline ransomware attack and threats to the Sellafield Nuclear facility have highlighted the urgency of securing industrial OT environments.

In a recent interview with Dr. Ryan Hartfield, CEO of Exalens, the seriousness of cyber-physical threats was emphasized. The potential impact of cyberattacks on key national infrastructure could lead to widespread economic, geopolitical, and societal unrest, presenting an existential risk. The conversation also delved into the cultural barriers that hinder the adequate securing of cyber-physical systems, emphasizing the need for a shift in mindset at various levels of organizations.

Dr. Hartfield touched upon the industrial cybersecurity teams and IT professionals’ different perspectives on security measures, indicating the need for aligning these teams’ goals for a more positive conversation. The challenge lies in shaping the lenses through which both cybersecurity and industrial engineering teams view the systems and environments, highlighting the cultural aspect of this issue.

Furthermore, the interview highlighted the role of governments and regulators in improving cyber-physical security. It was emphasized that the government needs to incentivize Operators of Essential Services (OES) providers to prioritize security, rather than relying solely on conversations with vendors. Legislative efforts in the US and the UK were mentioned as attempts to drive security control in industrial sectors, but the need for mandatory frameworks and controls was emphasized.

Dr. Hartfield proposed an analogy comparing the need for cybersecurity measures in cyber-physical systems to the safety controls in cars. He highlighted the importance of attaining a certain standard and certification for cybersecurity measures, as the risks associated with not doing so are significant.

In conclusion, the interview emphasized the need for organizations to bridge the cyber-physical gap by implementing robust cybersecurity policies. It was also recommended that organizations continue to connect and automate their systems to achieve digital transformation across industrial operations while ensuring the security of their critical industrial sectors. For more information on bridging the cyber-physical gap, organizations were encouraged to visit the Exalens website.

Overall, the conversation with Dr. Hartfield shed light on the pressing need for proactive and comprehensive cybersecurity measures in protecting cyber-physical systems and industrial environments. It highlighted the potential severity of cyber-physical threats and the imperative of government intervention to drive security control and incentivize OES providers to prioritize cybersecurity. The interview also underscored the need for a cultural shift within organizations to align the goals of cybersecurity and industrial engineering teams, ultimately emphasizing the importance of creating a unified approach to securing cyber-physical systems.
