Analyst(s): Earl Perkins


Identifying myths is the first step to addressing cybersecurity issues for operational technology and IIoT. This research explores common myths, realities and actions that security and risk management leaders should take to deliver a digital security strategy encompassing IT, OT and IoT.

Table Of Contents
  • Key Challenges



  • Myth 1: OT Systems Face the Same Risks as IT Systems, So OT and IIoT Can Use the IT Methodologies to Calculate Risks and Assess Threats
  • Myth 2: IT and OT Cultures Are Too Incompatible and Distinctive to Develop and Implement a Single or Common Cybersecurity Strategy
  • Myth 3: IT, OT and IIoT Cybersecurity Should Be Addressed as a System by a Single Team Reporting to One Executive
  • Myth 4: Use IT Cybersecurity Design and Management to Secure OT and IIoT Initiatives, and OT and IIoT Security Needs Will Be Met
  • Myth 5: OT and IIoT Systems Are Too Specialized and Unique to Use Off-the-Shelf Solutions and Require Customization to Secure OT Systems
  • Myth 6: The Air Gap as a Means of OT Network Segmentation for Securing Networks Is Dead
  • Myth 7: Cloud-Based Cybersecurity Solutions and Automation of Cybersecurity Responses Are Not Realistic for OT and IIoT Systems
