Despite the mining industry’s operational technology (OT) systems being vulnerable to cyberattacks, many decision-makers still see these threats as purely an IT issue, even though a breach could potentially disrupt mining operations.
By compromising OT systems, cyberattacks can halt mineral extraction processes with severe consequences, including an impact on profitability and damaging reputations, leading to a loss of investor confidence. In the worst-case scenario, an OT hack can endanger the health and safety of mineworkers. Furthermore, OT systems generate vast amounts of historical mining data, which, if leaked, can reveal sensitive information to the market or, if lost, can negatively affect future decision-making.
Consequently, this can result in mining houses suffering reputational damage too, as disruptions to operations can affect their share price, cast doubt over their future production capabilities and damage their relationships within the industry.
While there is traditionally role segregation between IT and OT management in mining operations, both areas are technology-based, and mining houses must recognise that both areas should ideally be overseen by the company’s Chief Information Officer (CIO).
From a cyber resilience perspective, IT and OT teams should ensure ongoing communication and collaboration as this would foster a better understanding of the impact of specific systems being unavailable and how this affects the entire business.
IT must be involved
IT will always be involved in the process of effectively managing and protecting OT systems, especially when it comes to securing systems and understanding how they fit into a bigger system architecture.
Regular system maintenance and compliance checks are essential for mining companies to ensure that their OT systems are adequately protected against cyber threats. OT systems form part of the safety ecosystem; thus, maintenance and compliance tests need to be treated like the safety drills that are regularly conducted at a mine.
It is vitally important that OT system operators understand the broader implications of what happens when the system is down. For example, they need to know what happens when the biometric access system goes down, and workers cannot be sent down the mineshaft or, for that matter, brought back up to ground level. Additionally, it is key to understand how various IT systems interlink and whether there are dependencies on specific components that need to be available for a critical system to work.
Furthermore, C-level executives must recognise that some cyber-risks extend beyond the IT department and that the right budgets must be made available to both IT and OT to protect these environments effectively. All executives thus need to understand that this must be part of their business objectives, and information security has to be at the top of the agenda at board meetings.
Incident response planning
At the same time, mining companies should also not underestimate the importance of having an incident response plan in place to identify, contain, and restore systems after a cyberattack. This would include planning for various scenarios when a breach happens and prioritising specific processes and systems based on the impact of the attack on the business.
Mines should also consider implementing cleanroom technology, which ensures a swift and uncontaminated recovery process for mining operations. Cleanroom technology provides a space on the network where systems can be recovered in an isolated environment and tests whether the data is clean and can be safely brought back into the production environment.
Ultimately, mining companies can benefit significantly from engaging with a specialist in data management and protection to secure their OT environments from cyber threats. While these companies may have general IT and OT skills, their core business remains mining. A data management specialist can bring their expertise to the table and help businesses draw up incident response plans and effectively protect their OT systems while allowing mines to focus on their core mineral extraction business.
