Enterprise IT
The digital context.
Identities, networks, endpoints, applications and dependencies that support services.
IT / OT / ICS · Operational Readiness
IT AND OT. ONE COORDINATED RESPONSE.
When an incident crosses from digital systems into industrial processes, the response depends on IT, OT / ICS, Cyber and Operations understanding the same situation and acting without losing operational control.
IT / OT Convergence
Two domains. One continuity objective.
Enterprise infrastructure and industrial environments have different technologies, constraints and priorities. The response needs a shared picture, not identical actions applied indiscriminately across every environment.
OT / ICS
The industrial context.
Control systems, automation, availability and process conditions.
Operations
The operational context.
Control rooms, production, services and priorities that guide decisions.
Business Continuity
The continuity to preserve.
Conditions and dependencies that need to inform containment and recovery.
Cyber-Physical Impact
From digital signal to operational impact.
The response must connect cyber evidence to the affected process. The reference sequence stays the same; the information, constraints and responsibilities that inform it change.
Detect
Confirm the signal and identify the systems and assets potentially involved.
What to observeVisibility of the event across digital and industrial environments.Triage
Assess severity, priority and initial context in relation to the affected processes.
What to observeAlignment between cyber priorities and operational criticality.Investigate
Correlate evidence with process status and dependencies between systems.
What to observeThe relationship between technical facts, uncertainty and effects on the process.Escalate
Engage the appropriate decision-makers with information on impact and operational constraints.
What to observeClarity of authority and involvement of the relevant functions.Contain
Coordinate containment by considering technical effectiveness, availability and process conditions.
What to observeFeasibility of actions and the ability to retain control.Recover
Restore systems and processes according to shared dependencies, conditions and priorities.
What to observeRecovery order and alignment with operational continuity.
Activities can overlap and repeat. The sequence prescribes neither universal timings nor automatic actions on plant systems. Decisions depend on the process, scenario and organisational responsibilities.
Control Room Readiness
The control room is part of the cyber response.
Industrial response extends beyond the SOC. Operators, OT engineers, IT, Cyber Defence and leaders need to share enough information to understand the impact and guide decisions.
A shared operational picture
Understand what is happening
together.
None of these three perspectives describes the incident on its own.
- Cyber evidence
- Signals, affected assets, available findings and matters still to be verified.
- Process status
- Availability, control, operating conditions and relevant dependencies.
- Operational priority
- Essential services, containment constraints and conditions for recovery.
Segregated Simulation
Exercise the response. Keep production separate.
CyberUP uses exercise environments segregated from the client’s production network. The systems, processes and dependencies included are defined by the objectives and the selected solution.
The exercise scope
The exercise does not run
on production systems.
The Arena environment is separate from production. Remote access, support and updates use controlled connectivity according to the agreed configuration.
Segregation does not mean absolute isolation from every network or immunity from external threats.
Agreed context
In dedicated solutions, emulation reflects the scope agreed with the client, not necessarily the entire infrastructure.
Two domains in the exercise
Scenarios connect IT and OT / ICS with relevant operational dependencies.
The right environment
Training Arena uses generic CyberUP environments. The choice between Physical, Smart and Training Arena depends on the context to be exercised.
IT / OT Incident Response
One incident. Connected responsibilities.
Technically possible actions need to be assessed against operational dependencies, availability and recovery conditions. The map clarifies how each function contributes to containment and recovery decisions.
Complementary responsibilities
Incident evidence
Cyber / SOC
- Responsibilities to exercise
- Share signals, analysis and an initial assessment of scope, while maintaining visibility as the incident develops.
- Interfaces to test
- The relationship between evidence, affected systems and information from IT, OT and Operations.
Infrastructure and identity
IT
- Responsibilities to exercise
- Establish the dependencies between networks, identities, applications and services relevant to the response.
- Interfaces to test
- Effects of IT actions on industrial environments and recovery conditions.
Control and process
OT / ICS
- Responsibilities to exercise
- Assess actions in the context of control systems and process conditions.
- Interfaces to test
- Compatibility of containment with availability, control and operational priorities.
Operational continuity
Operations / Control Room
- Responsibilities to exercise
- Share process status, production priorities and the conditions needed for continuity.
- Interfaces to test
- Coordination between the control room, technical functions and recovery activities.
Direction and priorities
Leadership
- Responsibilities to exercise
- Align risk, organisational priorities and responsibilities when the incident extends beyond the technical domain.
- Interfaces to test
- Information for decisions and direction for containment and recovery.
Authority depends on the organisation. A function may contribute to several activities; the control room’s role is not limited to recovery.
Industrial Business Continuity
Industrial continuity needs practice.
Simulation should produce evidence on visibility, coordination, containment and recovery of essential processes. What is observed in the Arena must not be confused with a guaranteed outcome in production.
Process continuity
Keeping processes available
The ability to identify and account for processes that need to remain available.
Cross-domain coordination
Connecting the domains
Quality of handovers between IT, OT, Cyber, the control room and Operations.
Containment discipline
Proportionate containment
Actions proportionate to the incident and operational constraints.
Recovery sequence
Prioritising recovery
The order in which systems and processes are restored, accounting for their dependencies.
Escalation clarity
Escalating clearly
Timeliness and quality of information provided to the appropriate decision-makers.
Decision quality
Making coherent decisions
Alignment of decisions with cyber risk, availability and operational continuity.
These are observation criteria, not results already assigned to the organisation. Exercise evidence is discussed in the debrief against the agreed objectives, conditions and responsibilities.
Where It Matters Most
Readiness for mission-critical environments.
Coordinating IT and OT is especially important where industrial processes, essential services and digital dependencies need to be understood together.
IT / OT Readiness
Explore the readiness of your IT/OT environments.
We build exercises and capability development programmes around your systems, industrial processes and the handovers that shape continuity during a cyber crisis.
