OT/ICS Security Assessment and Audits

In today’s interconnected world, Operational Technology (OT) and Industrial Control Systems (ICS) are increasingly exposed to cyber threats. These systems, which manage critical infrastructure and industrial processes, require robust security measures to ensure their resilience. CyberIntelSys specializes in OT/ICS Security Assessments and Audits, delivering tailored solutions to safeguard your operations from evolving cyber risks.

Why Are OT/ICS Security Assessments Vital?

An OT/ICS Security Assessment evaluates the vulnerabilities and security controls within an organization’s OT and ICS environments. The primary goal is to identify and mitigate potential threats that could compromise the integrity, availability, and confidentiality of critical systems.

By conducting regular assessments and audits, organizations can:

• Detect vulnerabilities in their OT/ICS environments.
• Ensure compliance with industry standards like IEC 62443.
• Strengthen the cybersecurity posture through continuous improvement.
• Protect against unauthorized access and cyberattacks.
• Minimize the risk of operational disruptions.

Comprehensive Approach to OT/ICS Security

At CyberIntelSys, our OT/ICS security assessments adopt a “defense in depth” strategy. This involves a multi-layered evaluation of people, processes, and technology to ensure a holistic understanding of the security posture. Here’s what our assessment entails:

Key Activities in OT/ICS Security Assessments

1. External Attack Surface Evaluation:
   • Identifying vulnerabilities in public-facing systems like APIs, websites, and remote access points.
   • Ensuring segmentation between IT and OT networks.
2. Network Vulnerability and Penetration Testing:
   • Assessing both external and internal networks to identify potential weaknesses.
   • Testing the effectiveness of security controls without impacting operational continuity.
3. Compliance and Standards Verification:
   • Ensuring adherence to industry standards such as IEC 62443.
   • Conducting audits to review policies, network architecture, and incident response plans.
4. Physical Security Assessment:
   • Evaluating access controls and on-site security measures.
   • Identifying gaps in safeguarding critical infrastructure.
5. Human Factor Analysis:
   • Testing personnel resilience to social engineering tactics.
   • Providing training to improve awareness and response.

CIA Triad: The Foundation of OT/ICS Security

CyberIntelSys uses the CIA Triad — Confidentiality, Integrity, and Availability — as a foundational model for our assessments:

• Confidentiality: Protecting sensitive data through encryption and access controls.
• Integrity: Ensuring data reliability and preventing unauthorized alterations.
• Availability: Guaranteeing timely access to critical systems and data.
