Securing Critical Operations

IARM's Expertise in IACS Cybersecurity Assessments - A Case Study

Our client, a Fortune 500 company and a global leader in industrial automation, entrusted us, IARM, with the crucial task of conducting a cybersecurity audit for one of their refinery factories. With a vast workforce spanning 24,500 employees and a presence in over 100 countries, their dedication to excellence mirrors our own commitment to safeguarding their operations through robust cybersecurity measures.


IARM was tasked with ensuring the protection of sensitive data, systems, and infrastructure within the manufacturing process of our client’s refinery factory.



Our Approach encompassed a comprehensive strategy tailored to their unique needs:

  • Preparation of Control Factory Acceptance Test (CFAT) and Site Acceptance Test (SAT)
  • Conducting a thorough Risk Assessment
  • Reviewing Security Configurations
  • Ensuring Compliance with industry standards such as IEC 62443 and NIST
  • Providing Cybersecurity Training for factory operators
  • Developing an Incident Management Process
  • Validating Business Continuity and Disaster Recovery Plans

The outcome of the project was the submission of a comprehensive CFAT/SAT document that documented the results of the audit. Our team also provided a vulnerability assessment report, highlighting the identified gaps and recommended solutions to address them.


This case study highlights IARM’s extensive expertise in industrial automation and control systems (IACS) cybersecurity audits. Our experience and commitment to delivering tailored security solutions have enabled us to assist our customer in protecting their critical assets and processes.
