Thankfully, there is a solution to this. Vulnerability management. Despite seeming straightforward, effectively managing vulnerabilities in OT systems significantly reduces risks and protects your organization from costly cyberattacks. 

In this article, we’ll discuss challenges and vulnerability management strategies to deal with them.

What Does Managing Vulnerabilities in OT Mean?

First things first. Managing vulnerabilities in operational technology (OT) environments differs from typical IT systems. In operational contexts, particularly when managing industrial control systems (ICS security), there’s a pressing need to safeguard crucial infrastructure. 

Unlike IT, OT environments include equipment such as programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, and various Internet of Things (IIoT) devices that often form the foundation of industrial operations.

OT vulnerability management is about dealing with security gaps in outdated or inherently insecure systems. This includes assessing potential flaws in software and components like user accounts and network configurations. The focus is broad. It must cover everything from insecure ports to account, service, and device management.

Vulnerability Management Steps:

  1. Assessment: Evaluate both software vulnerabilities and inherent design risks across assets.
  2. Prioritization: Decide which issues to address first based on their potential impact and ease of exploitation.
  3. Remediation: Implement solutions—often more than just a simple patch. This can involve reconfiguring settings or deploying alternative controls without typical reliance on conventional IT tactics.

A key challenge is that many OT devices must remain functional continuously, making it difficult to take them offline for patching or updating without impacting operations. Therefore, effective management in this realm requires an understanding that vulnerabilities in OT aren’t limited to software issues.

Engaging in an OT vulnerability management program is a hands-on, collaborative effort. This can involve multiple teams to ensure that the sensitive nature of OT and ICS networks doesn’t clash with the solutions applied. Adopting meticulous, tailored approaches to such systems makes managing vulnerabilities essential to maintaining security and ensuring that these critical operations run smoothly.

Challenges and Strategies for Managing OT Vulnerabilities

Inventory Challenge: Missing Asset Details

In many operational environments, asset tracking is alarmingly inadequate. Fingering through outdated spreadsheets or pooled data from various origins often leaves you with a patchy image of your asset landscape. Without a comprehensive registry, gauging the scope of new vulnerabilities and deciding which OT systems can receive patches becomes a headache.

Asset listings shouldn’t merely be an enumeration. You need solutions that deliver deep insights into each device. This means understanding the critical roles assets play, their operational layers, and whether they allow remote access. Enhancing the context around each asset enriches vulnerability evaluations and threat prioritizations.

Many firms have turned to passive surveillance or network-based systems to start building an asset ledger, but these tools typically fall short. For instance, listening devices can’t catch assets that aren’t directly feeding data through them, often resulting in major blind spots, like serially connected equipment. You need a comprehensive solution that directly interacts with endpoints, offering both wide and detailed visibility.

With a thorough asset inventory and insightful data analyses at your fingertips, vulnerability management transforms into an actionable strategy. Comprehensive asset details, going beyond basic vulnerability scores, help tailor effective remediation plans, enabling you to address threats in a more focused manner.

Challenge: Identifying System Weaknesses

Vulnerability scanners are abundant but not always suited for OT environments. These scanners typically operate by applying the most recent threat markers to devices, creating vulnerabilities that are anticipated for IT rather than OT settings. For OT, where devices interact delicately over many ports, a heavy-handed scanning approach can introduce actual disruptions.

Scans customized for OT take a gentler approach to avoid impacting operations, targeting only the most robust systems during planned outages. While these softer scans are crucial for operational safety, they often miss critical data. This scenario highlights gaps, leaving you with outdated or incomplete vulnerability maps.

An alternative is embracing a dual approach—agent-based management for OS devices paired with agentless tools for network and communication gear. Such a strategy offers detailed insights in real-time, thus enhancing protective measures. Cross-referencing this enriched asset database with vulnerability repositories, like the National Vulnerability Database, helps pin down your infrastructure’s most exposed areas.

Challenge: Deciding Which Vulnerabilities Matter Most

Large volumes of vulnerabilities can become overwhelming. Properly ordering these flaws is crucial for efficient risk management. Prioritization means weighing system criticality, operational impacts, and protective measures.

You should focus on assets that, if compromised, could severely impact essential operations. Another crucial factor is determining if a vulnerability represents a feasible attack path, whether due to inadequate hardening or remote access permissions. Guidelines such as the Common Vulnerability Scoring System (CVSS) contribute to understanding vulnerability severity, yet a context-intensive assessment of asset interconnections is often more revealing.

Challenge: Addressing Vulnerabilities Swiftly

Timing is everything when it comes to fixing vulnerabilities. You need transparent processes to ensure identified risks aren’t left unattended.

Efforts should be made to establish rapid vulnerability response protocols. Given the intricate dependencies within OT environments, balancing this act without disrupting operations requires fine-tuned coordination. A proactive approach involves continuously updating both detection mechanisms and patch management systems, ensuring you’re ready to act when new vulnerabilities are discovered.

Challenge: Monitoring the Vulnerability Management Lifecycle

Continuity in monitoring your system-wide vulnerability management is essential to account for progress and tackle ongoing challenges. Moving vulnerabilities through a cycle—detection, analysis, remediation, and reassessment—demands persistent tracking and documentation.

Documenting each step in the cycle aids in understanding where improvements can be made and ensures that no step stalls over time. Regular vulnerability audits offer you a clearer picture of the evolution of your network’s defenses and provide opportunities to refine your strategies.

Managing vulnerabilities in OT environments presents numerous challenges. By developing a more nuanced understanding of your asset inventory, identifying vulnerabilities, efficiently prioritizing them, closing them in due time, and keeping track of the whole process, you enhance the security and resilience of your OT infrastructure.
