Systems & dependencies
Which control systems support the process? What relies on them, and where are the gaps in the asset information?
OT security assessment for industrial systems.
Scope an OT cybersecurity assessment around the systems that support production. Explain your architecture, access arrangements and operating constraints before agreeing the work.

01 / Review areas
A scope grounded in the facility.
These topics structure the first conversation. The agreed scope determines which systems and controls are examined.
Architecture & access
How are networks separated? How do staff, contractors and suppliers reach the systems they need?
Readiness & recovery
What happens when visibility or control is lost? Which responsibilities and recovery arrangements need review?

Questions
What teams usually ask.
Does an assessment require active testing?
The methods must be agreed for the facility. An assessment enquiry is not authorisation to scan, change or test a production system.
Can we start without a complete asset inventory?
Describe what is available and where information is incomplete. Documentation gaps can be considered when defining the work.
What should the initial enquiry contain?
The facility type, the systems in scope, the concern driving the assessment and any access restrictions. Do not send credentials or restricted network details through an ordinary enquiry.
