Identity Security Strengthens OT Resilience Against Emerging Cyber Threats
In an era where cyber threats are increasingly sophisticated, identity security has emerged as a critical priority for organizations managing critical infrastructure and industrial environments. The convergence of information technology (IT) and operational technology (OT), coupled with heightened connectivity and remote access requirements, has created new vulnerabilities that malicious actors are eager to exploit.
A recent webinar titled “From Credentials to Catastrophe: Securing OT Before the Next Colonial Pipeline,” hosted by CPI Media Group in collaboration with Delinea, highlighted the pressing need for organizations to fortify their identity security measures. The session featured insights from Delinea experts, including Andrea Scott, Product Marketing Manager; Alex FitzGerald, Product Marketing Manager; Brance Spradlin, Global Identity Specialist; and Albert Beattie, Senior Technical Partner Manager.
The Evolving Landscape of OT Security
cybersecurity threats targeting industrial environments have evolved dramatically over the past decade. The notion that OT systems could remain insulated from external threats is no longer viable in a landscape characterized by remote monitoring, cloud connectivity, predictive maintenance, and third-party support services.
As organizations continue to manage IT and OT domains separately, they inadvertently create blind spots that attackers can exploit. This reality is prompting a shift toward unified governance models that offer a comprehensive view of cyber risk across the organization. The involvement of boardrooms in these discussions is increasing, as the ramifications of successful cyberattacks extend far beyond mere technological concerns.
Production downtime, supply chain disruptions, revenue losses, regulatory scrutiny, and safety issues can rapidly escalate a cybersecurity incident into a significant business continuity crisis.
Lessons from High-Profile Cyber Incidents
The webinar referenced several high-profile cyber incidents that underscore the risks facing industrial organizations today. Notable examples include the Triton attack on safety systems at a petrochemical facility in Saudi Arabia, the Shamoon attack on Saudi Aramco, the Colonial Pipeline breach in the United States, and the activities of the Volt Typhoon threat group. Each of these incidents illustrates how compromised credentials, trusted access, or poorly governed identities can serve as entry points into critical environments.
A key takeaway from the discussion is that attackers increasingly rely on legitimate credentials rather than sophisticated malware. This trend allows malicious actors to blend into normal operational activities, making detection significantly more challenging. Many modern attacks begin not with a breach of the perimeter but with seemingly legitimate access.
Identity as the New Control Plane
While network segmentation remains a vital component of OT security, the experts emphasized that identity has become the most effective lens through which organizations can understand and manage risk. Every engineer, contractor, vendor, administrator, application, machine identity, and service account represents a potential access pathway.
The growth of automation, cloud services, and artificial intelligence is accelerating this challenge, leading to a rapidly expanding population of non-human identities that require governance equivalent to that of human users. Organizations must achieve visibility into who has access, what actions they can perform, when they can act, and how quickly permissions can be revoked. Failure to govern identities consistently across IT and OT environments creates dangerous gaps that attackers can exploit.
The Challenge of Third-Party Access
Third-party access emerged as a significant concern during the webinar. Industrial operations often rely on equipment manufacturers, contractors, service providers, and maintenance teams that require remote connectivity to critical systems. Many organizations still provide access through persistent VPN connections and shared accounts, often with minimal oversight once access is granted.
Problems frequently arise when vendor relationships end but accounts remain active. Dormant credentials can linger for months or even years, creating unnecessary exposure and expanding the organization’s attack surface. Limited visibility into vendor activity further complicates the challenge. Stronger governance of third-party access is seen as one of the most effective ways to mitigate OT identity risk.
Roadmap to Enhanced OT Identity Security
Building a mature identity security program does not necessitate replacing existing infrastructure or undertaking disruptive transformation projects. The experts outlined a maturity journey that begins with basic visibility and progresses toward comprehensive governance. Early-stage environments often rely on shared credentials and have limited auditing capabilities. More advanced organizations implement privileged access management, just-in-time authorization, session monitoring, multi-factor authentication, role-based controls, and identity governance processes.
The ultimate goal is to achieve a zero-trust model in which access is granted only when necessary, credentials are protected from users, privileged sessions are monitored and recorded, and permissions are automatically revoked once tasks are completed. Delinea identified three core pillars for achieving this outcome: protecting privileged credentials, securing remote access through brokered connections rather than traditional VPNs, and providing comprehensive visibility into privileged activity through monitoring, auditing, and session recording.
Prioritizing Visibility
A consistent recommendation from all panelists centered on the importance of visibility. Organizations must have a clear understanding of the identities operating within their OT environments before they can effectively manage risk. Discovering privileged accounts, vendor access pathways, service accounts, and remote sessions provides the foundation for stronger governance and informed decision-making.
Quick wins can often be achieved by focusing on high-risk areas such as third-party access and privileged accounts. Enhanced visibility enables organizations to transition from assumptions to evidence-based risk management, laying the groundwork for a broader identity security strategy.
Identity security is no longer solely an IT concern. Modern industrial environments depend on trusted access to maintain operations, support innovation, and drive efficiency. Organizations that can effectively govern these identities will be better positioned to protect critical infrastructure, enhance resilience, and reduce the likelihood of operationally disruptive cyber incidents.
