OT SECURITY GAP ANALYSIS

Identify and Prioritise OT Cybersecurity Gaps

A structured review of the current industrial security posture, identifying weaknesses, missing controls and practical opportunities for improvement.

Move from general concerns to prioritised actions

Many industrial sites recognise the need to improve cybersecurity but do not have a clear view of their most important gaps. A gap analysis provides a structured baseline and helps separate urgent issues from longer-term improvements. The review can be aligned with internal requirements, customer specifications, IEC 62443 principles or an agreed assessment checklist.

Typical review domains

  • OT asset visibility
  • Network architecture
  • Segmentation
  • Firewalls and access-control lists
  • User accounts
  • Administrative access
  • Password practices
  • Remote access
  • Engineering workstations
  • System hardening
  • Antivirus or application control
  • Removable media
  • Backup and restore
  • Patch management
  • Vulnerability handling
  • Time synchronisation
  • Logging and monitoring
  • Physical access
  • Supplier access
  • Change management
  • Incident preparation
  • Security documentation

Finding priorities

Critical attention

Conditions that may create significant exposure or affect essential operational safeguards and require prompt review.

High priority

Important weaknesses that should be addressed through planned technical or procedural actions.

Medium priority

Gaps that should be included in the improvement programme and addressed according to operational constraints.

Improvement opportunity

Documentation, process or defence-in-depth enhancements that strengthen long-term security maturity.

Deliverables

  • Current-state summary
  • Gap register
  • Evidence references
  • Priority classification
  • Immediate actions
  • Short-term actions
  • Medium-term actions
  • Documentation improvements
  • Dependencies and constraints
  • Suggested roadmap
  • Optional follow-up workshop

Assessment limitations

A gap analysis is based on the agreed review scope and information made available. It is not a penetration test and does not prove that the environment is free from vulnerabilities or compromise.
