Master Risk Assessment: Your Path to Absolute Security
Operational Technology (OT) systems serve as the backbone of modern industry, playing a pivotal role in controlling and monitoring critical processes. Yet, these invaluable systems fall victim to an increasing number of cyber attacks, necessitating urgent OT risk management to identify and address vulnerabilities. This is where Zealinx comes in, offering comprehensive IEC 62443 compliance risk assessment services that precisely pinpoint cyber security risks within your OT environment.
Uncover the Key Aspects of an Risk Assessment:
- Identifying the assets that comprise the OT environment under consideration
- Categorizing and organizing the identified assets into security zones and conduits
- Conducting a Business Impact Assessment (BIA) to ascertain critical OT assets
- Identifying and analyzing potential threat sources/actors and associated scenarios
- Assessing the effectiveness of existing controls
- Identifying gaps and vulnerabilities
- Recommending additional mitigating controls
- Assigning risk ratings, prioritizing, and making remedial recommendations
- Delivering a formalized assessment report
Our outcome-focused approach ensures that any recommended actions are aimed at delivering tangible risk reduction. By providing organizations with a clearer understanding of the "What, Why, and How," our assessments empower them to make informed decisions regarding OT cyber security improvements, including associated costs. Rest assured, our assessments align with industry best practices and adhere to standards/frameworks such as ISO/IEC 62443, ISO/IEC 27001, NIST, and ISF.
At a high level, a "cyber" risk assessment helps build a clear understanding of risks in your OT environment and the potential impact they could have on your organization. The assessment process focuses on outcomes and assigns a "risk rating" to worst-case threat scenarios. These scenarios are evaluated under different situations: without mitigating controls (inherent risk), with current controls (residual risk), and with additional controls (target risk). A thorough analysis is conducted to evaluate existing controls for each threat scenario, determining if they sufficiently reduce the risk or if enhancements are required.
The assessment also considers the balance between risk, benefits, cost, and complexity, allowing for pragmatic prioritization of remedial efforts. Risk ratings are commonly presented using a "Risk Assessment Matrix" (RAM), which provides a holistic view of cyber risks for team members and stakeholders. Each organization's risk tolerance may vary depending on industry and historical occurrences.
Streamline your risk management process
Our risk assessment process includes the following key steps:
- Categorize OT assets based on their criticality to the organization's business operations (e.g., High, Medium, Low).
- Prioritize threat scenarios that may result in high-consequence events for the organization.
- Consider real-world cyber scenarios seen across industries for comprehensive coverage.
- Evaluate the effectiveness of existing controls for each threat scenario.
- Determine risk ratings based on impact and likelihood.
- Identify additional controls that can further reduce risk.
- Ensure that the proposed controls are realistic.
- Update the risk ratings considering the addition of remedial controls.
- Prioritize risks based on the highest risk rating in descending order.
- Determine which risks require immediate action and allocation of resources.
- Document the assessment in a formal report.
- Include an executive summary, a description of the current situation, risk exposure, findings, observations, and recommendations.
- Conduct a high-level feedback session with executive-level stakeholders.
- Provide an overview of the assessment outcome.
- Plan the next steps and conclude the engagement.
