Cybersecurity: Risk Moves Squarely to Operational Technology
Data breaches, ransomware attacks and now, operational shutdowns. Recent events bear out that cyber strikes are not reserved solely to data breaches and IT systems but now include Operational Technology (OT) and industrial controls to disrupt operations, distribution and the entire food supply chain.
JBS Foods, the one of the world’s largest meat producers, was leveled by a cyberattack in early June, affecting U.S. and Australia operations. In a public statement, the organization revealed that it paid the equivalent of $11 million in ransom in response to the criminal hack against its operations. “At the time of payment, the vast majority of the company’s facilities were operational. In consultation with internal IT professionals and third-party cybersecurity experts, the company made the decision to mitigate any unforeseen issues related to the attack and ensure no data was exfiltrated,” according to company documents.
There’s a security divide that shouldn’t be there—distinct lines between Cyber, OT and physical security teams that has resulted in disjointed and ineffective detection, mitigation and response to risk—forged by years of siloed departments.
It’s not a new problem—in fact the vulnerability of the critical infrastructure has been a discussion for decades. Moving to a converged approach across all departments, including HR, IT/cyber and OT/SCADA can effectively secure our most critical food production and distribution resources while actively enforcing compliance and company policies. Identity and Access is at the center of it all and the best way to holistically protect the enterprise.
In the example of high-profile enterprise Molson-Coors, a cyberattack in March centered on ransomware. In its SEC filing after the event, the beverage giant stated that the attack “has caused and may continue to cause a delay or disruption to parts of the company’s business,” which includes brewery operations, production and shipping.
The February attack on a Florida Water Treatment plant, hacked by compromise to a remote access software program on a facility computer, is still another stark reminder of the growing dangers of cyber-physical threats and that even employees can be part of the problem.
You can see just how fragile and vulnerable our supply chains and critical business processes have become. Cybercriminals now realize how disruptive and lucrative attacks targeting these systems can be so they will continue unabated without immediate stop-gaps.
Because these attacks have become blended and omni-present on every part of the critical infrastructure, executives need to move beyond IT-centric cybersecurity to minimize supply threats. This emergence of new attack vectors has other implications. It highlights the dire need to transition from siloed IT, OT, HR and physical security to a converged approach, yet executives remain at odds with how to execute this while working in their own bubbles.
The threat has become even greater than the organization itself. According to predictions by Gartner liability for cyber-physical security incidents will “pierce the corporate veil to personal liability,” for 75% of CEOs by 2024.
Security Convergence Key Ingredient to Digital Transformation
As the food industry continues to digitally transform, systems and processes move to rapidly connect. Security convergence, centered around identity and access governance, links all these separate departments and operations, so communications and processes actively and collectively address and shore up risk preemptively. Events, exceptions, alerts, alarms and targeted attacks on all points, including the network, control systems and physical security can be integrated for a coordinated and cohesive response.
Securing our most important critical resource—the food supply chain—means correlating threats across underlying HR, IT, physical security and OT used in production and processing. Physical access control and identity now links to specialized plant applications like manufacturing execution systems (MES), plant historians and demand management from ERP that can deliver information directly to production. Monitoring insider and contractor access to modifying batch recipes provides alerts and detection when the addition of a preservative has been suppressed, causing a contaminated batch to be produced, for example.
Integrating seamlessly with HR applications, converged software further prevents insider threat by automating background checks and risk analysis during the on-boarding and off-boarding process for employees and contractors.
The threat landscape today demands a single solution to manage operational risk and security. The following just one example of how this converged approach works.
A fictitious company named Big Food was dealing with disgruntled production foreman Tom. Tom not only had physical access to the production floor, but was intimately familiar with the control system settings to configure recipes for the MES.
Security software’s real-time link to SAP SuccessFactors HCM provided critical real-time data that identified Tom’s history of workplace issues. When Tom accessed the plant area after his normal shift hours, the security platform detected that he was making unusual changes to the production settings to eliminate the addition of preservatives. An alert was immediately sent to security operations staff as well as the plant manager. Incident prevented, with huge savings from avoided downtime and protection from loss of reputation to the company brand.
The food and beverage industry must meet high quality standards and adhere to rapid production cycles to preserve nutrition value and freshness. Convergence and automation are the keys to achieving these goals. As OT and IT networks become increasingly interconnected, OT environments become more exposed to cyber-physical attacks, which can result in tainted products, downtime and revenue losses. Security solutions secure enterprise IT applications and plant applications deliver continuous monitoring that prevents sabotage, acts of terrorism and other malicious acts. There’s also the ability to manage other supply chain risks, including changes to master data and transactions as well as the movement of goods and arrival notifications requirements by the FDA.
Today’s malicious actors don’t think in silos but most companies still do. As security and technology leaders we are compelled to rise and meet the challenge. It’s clear that only a converged approach, beyond IT-centric cybersecurity, is the way forward.
