Connect the process to its digital dependencies, recovery materials and responsible owners. Make the evidence and remaining assumptions clear before the next recovery activity.
Critical Process Recovery Readiness examines the digital functions, recovery materials, access, responsibilities and sequence behind recovery of one agreed operational process. Zeroday works with technical owners to build an ordered workpack and identify readiness gaps. The record separates documented arrangements from demonstrated, failed and untested conditions. Exercises require their own agreed scope, site authorization and appropriate technical providers.
Start with a recovery question, planned upgrade, equipment handover or provider transition. The useful question is concrete: what must return before this process can produce acceptable output, and what evidence supports the current arrangements?
Identify one production or processing step, its required digital functions and the supporting systems included in the review. Dependencies may involve control configurations, operator or engineering workstations, operational applications and shared services.
Agree the treatment of upstream or downstream systems, provider interfaces and dependencies outside the immediate process boundary.
Bring the process context, available recovery plans, material inventories, handover records and known concerns. Identify technical custodians, operational acceptance authority and providers whose knowledge or participation is needed.
Record access constraints, missing documentation and uncertain responsibilities. The scope distinguishes an available-evidence review from additional information gathering or an exercise.
Which digital functions and supporting services are required for the agreed process?
Which configurations, images, software versions, licenses and other materials are needed?
Who maintains those materials, and what evidence supports their relevance?
Which access arrangements, provider contributions and approvals are prerequisites?
What order do owner-approved procedures require, and where are dependencies unresolved?
Which conditions have been demonstrated, failed or remain untested?
A backup listed in an inventory is one input. Its presence alone does not demonstrate that the necessary digital functions or the process can be restored.
A documented process boundary and digital dependency record.
A recovery-materials register with custodians and known gaps.
An ordered workpack connecting tasks, prerequisites and responsibilities for owner-approved procedures.
A readiness-gap record covering missing materials, unclear access and unresolved dependencies.
A distinction between documented arrangements, demonstrated conditions, failed steps and untested assumptions.
Maintenance and handover needs, with exercise evidence where separately scoped.
Acceptance asks whether the workpack accurately represents the scope and available evidence. It does not establish a guaranteed recovery outcome. See the recovery readiness acceptance criteria in the buyer guide.
This fictional example concerns an operator workstation supporting one agreed process. It is not a client case or restoration procedure.
Material: an image is listed in the site's example register.
Custodian: the internal IT/OT owner is named.
Unknowns: the relationship between the image and the current application configuration, licensing and provider requirements has not been established.
Status: documented material; restoration remains untested in this example.
Next work: the owner and provider review the missing information and prerequisites.
Next decision: site authorities determine whether a separately scoped exercise is appropriate. The record does not infer recovery success.
If an exercise is agreed, preserve its conditions, evidence, unsuccessful steps and limitations. Successful work within one set of conditions should not silently become a claim about every future recovery situation.
Zeroday leads the agreed review, coordination and readiness record. Your technical owners and providers supply equipment knowledge, materials and owner-approved procedures. Site authorities retain safety decisions, operational acceptance and approval to return equipment to service.
Andres Torres leads the executive relationship and program direction. Specialist participation and technical review are defined by the scope and qualifications required for the environment.
This engagement is planned readiness work. It does not imply emergency response coverage, equipment engineering approval or authority to perform unscoped restoration activity. A broader security baseline may call for an OT Security Assessment.
NIST SP 800-82 Rev. 3 addresses OT security in the context of performance, reliability and safety. Applicable guidance and review criteria are agreed for the process being examined.
A completed workpack needs an identified custodian and a way to address changes in systems, materials, providers or responsibilities. Record maintenance and handover needs during the engagement.
If recurring review is useful, discuss its inclusion in a separately agreed ongoing OT service. Define the change triggers, evidence inputs, review cadence and decision owners. Scheduled review does not imply a repeated restoration exercise.
Yes. Describe what exists and what is missing. The scope should make information-gathering needs and limitations explicit, with unknown conditions preserved in the record.
Only when it is separately scoped and authorized with the appropriate technical providers. The workpack distinguishes evidence from a document review and evidence from an actual exercise.
Share the process involved, the change or concern that prompted the review and the technical owners who can participate. Keep configurations and confidential recovery records out of the public form.
