Breakdowns in coordination between teams that should jointly manage risk. In manufacturing security, communication gaps often leave IT, operations, and leadership with different assumptions about ownership, access, and response. The result is delayed remediation, inconsistent controls, and blind spots that attackers can exploit across connected environments.
Expanded Definition
Communication gaps are breakdowns in shared understanding across teams that have overlapping responsibility for risk, control, or response. In security settings, the term is broader than a missed update or a slow handoff. It covers unclear ownership, inconsistent terminology, and unspoken assumptions that leave different groups acting on different versions of the same situation.
The boundary matters. A communication gap is not simply poor messaging; it becomes security-relevant when the gap changes how a control is interpreted, who is expected to act, or how quickly an issue is escalated. In manufacturing environments, that often means IT, operations, engineering, and leadership each believe someone else owns the decision. NHIMG treats that distinction as practical, not semantic, because control failure often begins as a coordination failure before it becomes a technical one.
There is no single standards body that defines the term itself, but the closest useful framing is cross-functional governance and risk ownership. For readers working with connected production environments, the OWASP Non-Human Identity Top 10 is relevant where communication gaps prevent teams from agreeing who owns machine credentials, service accounts, or automation trust boundaries.
Examples and Use Cases
Communication gaps usually show up as operational friction long before they appear in incident reports. Common examples include:
- IT believes a plant-floor application is owned by operations, while operations assumes central security handles access review and logging.
- A vendor connection is approved without a shared understanding of who can revoke it, test it, or confirm when it is no longer needed.
- Leadership receives a risk summary that omits the dependencies most important to plant availability, so the response decision is made on incomplete context.
- Teams use different terms for the same asset or trust relationship, which makes ticketing, escalation, and remediation inconsistent.
- Automation or service credentials are changed in one team’s process, but the downstream system owners are not told, creating avoidable outages or failed jobs.
In practice, the tradeoff is between speed and clarity. Highly distributed environments move faster when coordination is lightweight, but they become fragile when nobody has a complete view of ownership. The issue is not always a lack of effort; it is often a lack of shared operating language and explicit decision boundaries.
Security Implications
When communication gaps persist, security work fragments into isolated actions that do not add up to a coherent control posture. One team may harden a system while another keeps an obsolete access path alive. One group may believe an issue is being contained while another continues normal operations on the assumption that risk was accepted. That mismatch creates delay, duplicate work, and control drift.
The concrete consequence is usually not a single failed safeguard but a chain of small failures: delayed remediation, missed escalation, inconsistent exception handling, and incomplete visibility into who can approve, change, or restore a service. In connected environments, those conditions create openings for lateral movement, unauthorized persistence, and extended exposure because defenders are not responding with a single shared understanding of the problem.
A useful practitioner observation is that communication gaps often surface first during change, incident response, or ownership transfer. If those transitions are undocumented or disputed, the organisation typically has a stronger process on paper than in operation.
Domain and Governance Relevance
In manufacturing security, communication gaps matter because operational technology, enterprise IT, and business leadership often manage different parts of the same risk surface. The subject is not just coordination hygiene; it affects whether access decisions, patch timing, recovery steps, and exception approvals are governed consistently across production and corporate environments.
Where NHI or machine identities are involved, the governance impact becomes more specific. A service account, API key, or automation credential can outlive the team that created it unless ownership, rotation responsibility, and revocation authority are clearly assigned. If that responsibility is ambiguous, the organisation may preserve access paths that nobody actively governs, which weakens trust in both change control and incident containment.
That is why communication gaps are a governance issue as much as an operational one. They expose whether the organisation can answer a basic control question: who is accountable when a shared system, shared credential, or shared dependency changes state?
Risk and Threat Considerations
Communication gaps create material exposure because they weaken ownership, visibility, and escalation across interdependent teams. In a manufacturing environment, that can leave connected systems, remote access paths, and automation credentials in place after the business thinks they have been reviewed or retired.
Failure mechanism: The risk materialises when teams hold different assumptions about who approves changes, who monitors access, or who confirms remediation. Attackers do not need the gap itself; they benefit from the delay, duplicate trust, and inconsistent control enforcement it creates.
Impact: The likely result is extended dwell time, failed containment, missed revocation, and a larger blast radius if a shared system or credential is compromised. In operational settings, the same weakness can also produce preventable outages when changes are made without a common understanding of downstream dependencies.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0, CIS Controls v8 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | GV.SC — Cybersecurity Supply Chain Risk Management | Shared ownership gaps often appear across supplier and internal control boundaries. |
| Recommendation — Map cross-team and third-party handoffs so ownership, escalation, and dependency risk are explicitly assigned. | ||
| CIS Controls v8 | 5 — Account Management | Communication gaps often leave account ownership and lifecycle decisions unclear. |
| 17 — Incident Response Management | Breakdowns in coordination directly affect escalation and containment during incidents. | |
| Recommendation — Assign clear account owners and review dormant access paths on a fixed schedule. Define response roles and communications paths before an incident begins. | ||
| NIST AI RMF | GOVERN — AI Risk Management Governance | When automation or AI workflows are involved, unclear ownership undermines governance. |
| Recommendation — Establish accountable ownership for AI-enabled workflows and the decisions they influence. | ||
Practitioner Guidance
Governance implication: Treat communication gaps as an ownership problem, not a messaging problem. The important question is whether each critical asset, access path, and response step has a named decision-maker who is understood by every team that depends on it.
What to watch for: Watch for repeated confusion during incidents, unclear handoffs during change windows, and inconsistent answers about who can approve access or remediate a finding. Those are usually the earliest signs that the organisation has a control gap hidden inside its coordination process.
