Mastering Security Maturity Assessment: Conducting Effective Evaluations for Industrial Systems

Do you think that industrial systems are more vulnerable to cyber threats than ever before in the current world? With the increasing sophistication of attacks on operational technology (OT) environments, organisations must proactively assess and bolster their security measures. Conducting an effective OT security assessment is a critical step in safeguarding these industrial systems.

Before we dive into the specifics of conducting an OT security assessment, let's clarify what it entails. An OT security assessment is a comprehensive evaluation of your industrial systems, aimed at identifying vulnerabilities and assessing potential cyber threats. It's a proactive approach to protect your critical infrastructure from evolving risks. Approximately 88% of organisations experience spear phishing threats within a year, according to Norton's stats.

1. Plan Your Assessment:
- Start by defining the scope of your assessment. Which industrial systems, processes, and assets will be included?
- Identify the necessary resources, both in terms of personnel and tools.
- Develop a realistic schedule that accounts for the complexity of your OT environment.

2. Identify Your Assets:
- Take a thorough inventory of all OT assets, including hardware, software, and networks.
- Ensure you have a complete and up-to-date understanding of your OT environment.

3. Assess Your Vulnerabilities:
- Employ a range of tools and techniques to assess vulnerabilities within your OT infrastructure.
- This may involve vulnerability scanning, penetration testing, and risk assessments.

4. Analyse Your Risks:
- Evaluate the vulnerabilities you've identified by considering factors like the likelihood of an attack, the potential impact, and the cost of mitigation.
- Prioritise your vulnerabilities based on this risk analysis.

5. Develop a Remediation Plan:
- Craft a detailed plan to address the most critical vulnerabilities.
- Your plan should include specific actions, timelines, and responsible individuals or teams.

6. Implement Your Remediation Plan:
- Execute your remediation plan diligently, which may involve patching software, deploying new security controls, or revising operational procedures.
- Ensure all changes align with your risk-based priorities.

7. Monitor and Maintain:
- OT security is not a one-time effort; it's an ongoing commitment.
- Continuously monitor your security posture to identify and respond to emerging threats or vulnerabilities.
- Regularly maintain your security controls and systems.

Involve OT Personnel:
Your OT experts possess invaluable knowledge of industrial systems. Their insights are critical in identifying and assessing vulnerabilities effectively.

Risk-Based Approach:
Focus your assessment on vulnerabilities with the highest potential impact. Prioritising risks ensures that your resources are allocated efficiently.

Diverse Toolkit:
There is no one-size-fits-all solution for OT security. Use a variety of tools and techniques to comprehensively evaluate your security posture.

External Expertise:
If your organisation lacks the in-house expertise for an effective OT security assessment, consider engaging a qualified security consultant with experience in industrial environments.
