RSC Sphere: Data Integration, Security and Trust

The Data Integration, Security and Trust Sphere establishes the governance layer that makes everything else credible. It focuses on system interoperability, data mapping, version control, audit trails, and security alignment for regulated environments. The content makes clear how execution data can move safely across ERP, MES, QMS, PLM, and supplier systems without compromising control. This sphere proves that interoperability and security can coexist in aerospace ecosystems.

  • processor

    In privacy and data protection contexts relevant to industrial and regulated environments, a processor commonly refers to an organization or individual that processes personal data on behalf of another party that determines why that data is processed.

    Core definition

    A processor is an entity that:

    • Processes personal data only on documented instructions from another party that decides the purposes and main means of processing (often called a controller or similar role in various frameworks).
    • Uses technical and organizational measures to handle the data, such as collecting, storing, transmitting, analyzing, or deleting it.
    • Does not independently decide new purposes for the data outside the instructions it receives.

    In industrial settings, a processor could be, for example, a cloud provider hosting production and quality data that includes personal data, an MES or ERP service provider operating a managed service, or an analytics vendor processing sensor and operator data for a manufacturer.

    Operational meaning in manufacturing and OT/IT

    Within manufacturing and industrial operations, the processor role appears in scenarios such as:

    • Hosted MES, historian, or quality systems where a service provider processes operator IDs, batch records, or deviation data on behalf of a plant or company.
    • Third-party monitoring, predictive maintenance, or OT security platforms that ingest log files, badge IDs, or IP information from production networks.
    • External HR, training, or access management tools integrated with shop-floor systems that handle personnel identifiers and access logs.

    Contracts and data processing agreements typically define what the processor is allowed to do with the data, retention expectations, sub-processing, cross-border transfers, and security measures. The organization that decides the purposes for using the data is responsible for ensuring that the processor is appropriately selected and managed.

    Relation to NIST 800-53 and GDPR

    Under GDPR, a processor is specifically defined as an entity that processes personal data on behalf of the controller. NIST SP 800-53 does not use the same legal terminology, but it provides control families that can be used by processors and controllers alike to manage privacy and security risks.

    In industrial environments, a service provider acting as a processor might implement NIST 800-53 security and privacy controls to support a manufacturer that has obligations under GDPR or similar privacy laws. The legal role (processor vs controller) comes from the applicable law and contracts, while frameworks such as NIST 800-53 help organize supporting controls.

    Common confusion

    • Processor vs controller: The controller (or similar role under other laws) decides the purposes and main means of processing. The processor follows those instructions and does not repurpose the data independently.
    • Processor vs joint controller or co-operator: If two organizations jointly decide purposes and essential means, they may both be considered controllers under some laws, not a controller and processor.
    • Processor (privacy role) vs CPU/processing hardware: In industrial automation, “processor” can also mean a CPU, PLC processor, or microprocessor that executes instructions. In privacy and compliance discussions, the term almost always refers to the data protection role, not the hardware component.

    Secondary meaning in industrial systems

    Separately from privacy terminology, in OT and IT engineering a processor can mean the hardware or logical component that executes instructions:

    • A central processing unit (CPU) in a server hosting an MES or historian.
    • The processing unit in a PLC, DCS controller, or embedded device on the shop floor.

    In this technical sense, a processor is part of the computing infrastructure and is not a legal role in data protection.

  • privacy-by-design

    Privacy-by-design is an approach to engineering systems, processes, and products so that privacy and data protection requirements are considered and integrated from the earliest stages of design and throughout the full lifecycle. It contrasts with treating privacy as an after-the-fact add-on or a single compliance step.

    In industrial and regulated manufacturing environments, privacy-by-design commonly refers to how organizations plan, implement, and document controls around personal data in IT and OT systems such as MES, ERP, QMS/LIMS, maintenance systems, and connected equipment platforms.

    Key characteristics

    Privacy-by-design typically includes:

    • Proactive consideration of privacy before deploying new systems, integrations, or analytics that use personal data (for example, HR data, operator IDs, training records, access logs, or customer data tied to serialized products).
    • Integration with system and process design, such as role-based access control, data minimization, pseudonymization or aggregation of data, and clearly defined retention and deletion behaviors.
    • Lifecycle view, covering requirements, design, implementation, validation/qualification, change control, operation, and decommissioning of systems that handle personal data.
    • Documented controls and traceability across policies, procedures, risk assessments, and technical configurations in systems like MES, DCS/SCADA, historians, and quality systems.
    • Alignment with security controls, where security standards and control catalogs (for example, NIST SP 800-53 or similar) are used to support but not replace documented privacy requirements and design decisions.

    Operational meaning in manufacturing

    In practice, privacy-by-design in industrial operations may appear as:

    • Conducting a privacy or data protection impact assessment when introducing new shop-floor monitoring, traceability, or workforce analytics tools.
    • Configuring MES or historian systems so identifiable operator data is only visible to specific roles and is logged in a way that supports audits without unnecessary exposure.
    • Defining how personal data is captured in batch records, deviation reports, training logs, or maintenance systems, and how long it is retained.
    • Integrating privacy controls into change control workflows, validation documentation, and configuration management for regulated environments.

    Common confusion

    Privacy-by-design is commonly confused with:

    • Security-by-design: Security-by-design focuses on protecting systems and data from unauthorized access or modification. Privacy-by-design overlaps with security but emphasizes how personal data is collected, used, retained, and exposed, including data minimization and purpose limitation.
    • A single regulation or standard: Privacy-by-design is a design and governance approach, not a specific law, certification, or framework. Organizations often use standards and control catalogs (such as NIST SP 800-53, ISO-based frameworks, or internal policies) as reference points to implement and evidence privacy-by-design.

    Relation to control catalogs such as NIST SP 800-53

    Control catalogs like NIST SP 800-53 provide structured security and privacy controls, terminology, and mappings that can support privacy-by-design. In many organizations, selected controls are tailored and mapped into existing QMS, ISMS, validation, and change control documentation to demonstrate how privacy requirements are designed into systems and processes. The catalog itself is not a turnkey privacy-by-design framework; it is used as input to a broader design and governance approach.

  • NIST Risk Management Framework

    The NIST Risk Management Framework (NIST RMF) is a structured, repeatable process defined by the U.S. National Institute of Standards and Technology for managing information security and cybersecurity risk to systems and organizations. It provides a life cycle approach for selecting, implementing, assessing, authorizing, and monitoring security and privacy controls for information systems.

    Core concept

    NIST RMF links system-level security and privacy activities to organizational risk management. It is commonly used for federal information systems in the United States and by many private-sector organizations that want a rigorous, control-based risk process.

    The framework is organized as a sequence of steps that apply across the life of a system. In its modern form, these steps commonly include:

    • Prepare: Establish context, roles, risk management strategy, and governance.
    • Categorize: Define the impact level of a system and the information it processes.
    • Select: Choose appropriate security and privacy controls from a catalog (often NIST SP 800-53), tailoring them to the system.
    • Implement: Put the selected controls into operation and document how they are used.
    • Assess: Evaluate if the controls are correctly implemented and effective.
    • Authorize: Management formally accepts residual risk and authorizes the system to operate.
    • Monitor: Continuously track control performance, system changes, and emerging risks, updating earlier steps as needed.

    Use in industrial and manufacturing environments

    In industrial and manufacturing contexts, NIST RMF is often applied to information systems and operational technology (OT) that handle production data, quality records, or connectivity between plant-floor systems and enterprise IT. Typical examples include:

    • Applying RMF steps to manufacturing execution systems (MES), historians, or SCADA/PLC networks that interface with regulated production.
    • Using NIST SP 800-53 controls under the RMF to define security baselines for plant systems that store batch records, electronic device histories, or other regulated data.
    • Aligning authorization and monitoring activities with internal governance, quality, and audit-readiness processes.

    RMF does not prescribe a specific technology stack. Instead, it provides a structure for integrating cybersecurity and privacy controls into system life cycle management, including design, commissioning, change control, and decommissioning of OT and IT systems used in manufacturing.

    What it includes and excludes

    NIST RMF includes:

    • A defined sequence of risk management steps for systems.
    • Guidance on selecting and assessing controls, often using NIST SP 800-53.
    • A governance-oriented process that ties technical decisions to organizational risk tolerance.

    It does not include:

    • An official certification program for organizations, plants, or systems.
    • Detailed configuration standards for specific vendors or products.
    • Industry-specific regulatory rules, although it can be mapped to them.

    Relationship to NIST SP 800-53 and similar documents

    NIST RMF is a process framework. NIST Special Publication 800-53 is a catalog of security and privacy controls that is often used within this framework during the “Select,” “Implement,” and “Assess” steps. Many organizations apply the RMF using 800-53 controls as building blocks for their security baselines.

    Organizations can implement RMF and align to NIST 800-53 controls, and can seek independent assessments of that implementation, but there is no official NIST-issued certification that a system or site is compliant with RMF or 800-53.

    Common confusion

    • NIST RMF vs. NIST CSF: The NIST Cybersecurity Framework (CSF) is a higher-level, outcome-focused framework that organizes cybersecurity activities into functions such as Identify, Protect, Detect, Respond, and Recover. NIST RMF is more system-focused and control-driven, often used where formal authorization and detailed control assessment are required.
    • NIST RMF vs. control catalogs: RMF is the risk management process. Control catalogs such as NIST SP 800-53 provide the individual controls that are applied within that process.
    • NIST RMF as a standard vs. certification: RMF is guidance for risk management, not a certifiable standard. It can inform internal policies, audits, and vendor requirements, but references to being “certified to RMF” are typically informal or inaccurate.

    Operational perspective in regulated manufacturing

    In regulated manufacturing environments, NIST RMF is often used as one of several reference frameworks for managing cyber risk to systems that impact product quality, data integrity, or safety. It may be:

    • Mapped to internal quality and validation processes used for commissioning and modifying OT/IT systems.
    • Integrated with change control so that security impacts are evaluated when modifying control systems or MES configurations.
    • Referenced in audits to explain how security controls around electronic records, access management, and data transmission are selected and overseen.

  • SIEM

    SIEM (Security Information and Event Management) is a class of security platforms that collect, normalize, store, and analyze log and event data from multiple systems to support threat detection, incident response, and security monitoring.

    Core meaning

    A SIEM commonly refers to software or a service that:

    • Ingests logs and events from many sources, such as firewalls, servers, endpoints, databases, applications, and OT devices
    • Normalizes and correlates events to identify patterns that may indicate security incidents
    • Raises alerts based on rules, correlation logic, and sometimes behavioral analytics
    • Provides dashboards and reports for security operations and compliance monitoring
    • Archives log data for forensic analysis and audit support

    In manufacturing and other industrial environments, a SIEM often collects data from both IT and OT, including MES, historians, SCADA, PLC gateways, identity systems, and network infrastructure.

    Operational use in industrial environments

    Within plants and regulated manufacturing operations, a SIEM typically:

    • Centralizes security-relevant events from production networks, corporate networks, and cloud services
    • Monitors access to critical systems like MES, batch servers, quality systems, and engineering workstations
    • Helps detect unauthorized changes to OT configurations, user accounts, or critical applications
    • Provides evidence of monitoring, logging, and incident handling to support frameworks such as ISO 27001 or similar security management standards
    • Supports investigations when there are suspected breaches involving shop-floor systems or production data

    What SIEM is not

    SIEM is not:

    • A replacement for endpoint protection, firewalls, or identity management tools
    • A control system or MES; it observes and analyzes events rather than executing production workflows
    • Guaranteed proof of compliance; it can provide supporting evidence but does not itself constitute certification

    Common confusion

    • SIEM vs. log management: Log management focuses on collecting and storing logs. SIEM includes log management but adds correlation, alerting, and security-focused analytics.
    • SIEM vs. SOAR: SOAR (Security Orchestration, Automation, and Response) tools automate workflows and responses to alerts. SIEM is primarily focused on detection and analysis, though some products combine both capabilities.

    Relation to ISO 27001 in manufacturing

    In the context of ISO 27001 and similar security standards, a SIEM is often used to:

    • Provide centralized logging for critical IT and OT assets
    • Demonstrate that security events are monitored and investigated
    • Support incident recording, metrics, and evidence for audits involving production and shop-floor systems

    Use of a SIEM does not by itself fulfill any specific control, but it can support multiple controls related to monitoring, incident management, and logging.

  • Personally Identifiable Information

    Personally Identifiable Information (PII) commonly refers to any data that can be used to identify a specific individual, either directly on its own or indirectly when combined with other information. PII is a core concept in privacy, information security, and regulatory compliance across many industries, including manufacturing.

    What Personally Identifiable Information includes

    PII typically includes, but is not limited to:

    • Direct identifiers such as full name, government-issued ID numbers, employee IDs, photos, or biometric data
    • Contact details such as home address, personal phone numbers, and personal email addresses
    • Identifiers that can single out a person in context, such as login IDs linked to a named employee, badge numbers, or machine/operator IDs tied to HR records
    • Data that becomes identifying when combined with other information, such as date of birth, job title, or location plus other attributes

    In regulated manufacturing environments, PII often appears in HR systems, training records, access control logs, visitor logs, supplier contact databases, and engineering or quality workflows where individual users are recorded as reviewers, approvers, or operators.

    What Personally Identifiable Information does not include

    Information is generally not treated as PII when it has been de-identified so that individuals cannot reasonably be re-identified. Examples include:

    • Aggregated production statistics that do not reference specific employees
    • Anonymized quality or safety metrics where operator IDs have been removed or irreversibly masked
    • Equipment identifiers (such as machine IDs) that are not linked to named individuals or HR records

    Whether information is considered PII can depend on the context and on applicable privacy or data protection laws. The same data element may be non-identifying in one context and identifying in another if it can be linked back to a person.

    Operational relevance in manufacturing and industrial systems

    In industrial and manufacturing settings, PII interacts with operational technology and information systems in several ways:

    • Access control and logging: Badge systems, MES user accounts, and audit trails often record which specific operator performed a step, creating PII in event logs.
    • Training and qualification records: Systems that track who is qualified to run certain equipment or perform certain procedures store PII linked to job roles, training dates, and performance history.
    • Supplier and customer contacts: Names and contact details of supplier engineers, quality contacts, and customer representatives are maintained in ERP, QMS, and collaboration tools.
    • Incident and deviation records: Corrective action, nonconformance, and safety incident records may reference specific individuals involved in a manufacturing event.
    • Remote access and monitoring: Logs from remote maintenance, OT security tools, and IT service management systems often include user identifiers that qualify as PII.

    Organizations typically define governance around where PII is stored in MES, ERP, QMS, LIMS, OT security platforms, and document control systems, and align handling practices with internal policies and applicable regulations.

    Relationship to NIST SP 800-53 and control families

    In the context of NIST SP 800-53, PII is specifically addressed in the PT (Personally Identifiable Information Processing and Transparency) control family. These controls focus on how organizations:

    • Collect, process, store, and share PII
    • Minimize PII and define its purpose of use
    • Provide transparency about PII handling practices
    • Integrate privacy considerations with security controls

    In regulated manufacturing environments, this typically applies to HR data flows, supplier and customer records, engineering and collaboration tools with user identity data, and monitoring or logging systems that capture employee activities.

    Common confusion

    • PII vs. personal data: Many data protection frameworks use the term “personal data” or similar. In practice, these concepts overlap heavily with PII, although specific legal definitions and scope can differ by jurisdiction.
    • PII vs. PHI: Protected Health Information (PHI) is a subset of personal information related to health status or care in certain regulatory frameworks. PII is broader and is not limited to health data.
    • PII vs. user credentials: Usernames and IDs may or may not be PII depending on whether they can be tied back to an identifiable person in a given context.

    Because definitions and regulatory scope can vary, organizations often document their own operational definition of PII and how it applies across their manufacturing and IT/OT systems.

  • multi-tenant

    Multi-tenant commonly refers to a software or system architecture in which a single deployed application instance and its underlying infrastructure serve multiple independent customers (“tenants”), while keeping each tenant’s data and configurations logically separated.

    Core characteristics

    In a multi-tenant architecture:

    • Shared application and infrastructure: All tenants use the same running application codebase and typically share compute, storage, and network resources.
    • Logical separation of data: Each tenant’s data is isolated through database schemas, row-level access controls, or equivalent mechanisms, even though it may be stored in the same physical database or cluster.
    • Tenant-aware configuration: Settings such as branding, workflows, integration endpoints, and access rules can vary by tenant while still using the same core software.
    • Centralized operations: Patching, monitoring, backups, and capacity management are handled centrally for all tenants.

    Multi-tenant architectures are common in SaaS platforms that support many client organizations, such as supplier collaboration portals, MES-related cloud services, or quality and document management tools offered as shared services.

    What it includes and excludes

    Multi-tenant typically includes:

    • Cloud or hosted systems where multiple customer organizations log into the same application environment.
    • Platforms where access controls, role models, and namespaces are designed to distinguish and separate tenant data and workflows.
    • Shared collaboration platforms where each manufacturer, supplier, or plant is treated as a tenant.

    Multi-tenant typically does not include:

    • Single-tenant deployments where each customer has its own dedicated application instance or environment.
    • Simple multi-user systems within a single organization, unless the architecture explicitly treats organizational units as separate tenants.

    Operational and compliance context

    In regulated manufacturing and industrial environments, multi-tenant platforms intersect with topics such as:

    • Access control and segregation of duties: Ensuring that users from one tenant (for example, a supplier) cannot view or modify another tenant’s data (for example, another supplier or customer site).
    • Data residency and ownership: Clarifying where data is stored and who can access it within a shared infrastructure.
    • Validation and change management: A change to a shared, multi-tenant system can affect many customers simultaneously, which influences validation strategies and release processes.
    • Information security management: Standards such as ISO 27001 are often applied at the level of the multi-tenant service provider’s information security management system, not as a guarantee of security for a specific tenant.

    Common confusion

    • Multi-tenant vs single-tenant: In single-tenant setups, each customer has a dedicated instance of the application or environment. In multi-tenant setups, many customers share the same instance. Some vendors offer hybrid models (for example, logically separate databases but shared application layer).
    • Multi-tenant vs multi-user: Multi-user simply means more than one user can access a system. Multi-tenant implies multiple distinct organizations or groups are intentionally separated within a shared system.
    • Multi-tenant vs multi-site: In manufacturing, multi-site often refers to different plants or locations within one company. These may be modeled as separate tenants in some platforms, but not always; the term multi-tenant is architectural, not organizational.

    Link to shared supplier collaboration platforms

    For shared supplier collaboration platforms, multi-tenant usually means that one cloud-based application environment serves many customer organizations and their suppliers. Each organization is treated as a separate tenant, with its own users, permissions, data spaces, and integration endpoints, while all tenants rely on the same underlying application, security controls, and infrastructure managed by the provider.

  • Jump host

    A jump host is a hardened intermediary server that users connect to first in order to reach systems located in a more restricted or sensitive network segment, such as an OT network or a production cell. It acts as a controlled gateway between less trusted networks (for example, the corporate IT network or the internet) and highly protected environments.

    How a jump host is used

    In industrial and manufacturing environments, a jump host commonly sits between IT and OT networks, or between external partners and internal systems. Typical uses include:

    • Remote access to control systems, HMIs, historians, or MES nodes on an OT network
    • Administrative access to servers located in a DMZ or high-security segment
    • Vendor or integrator access to specific plant systems without exposing the full network
    • Centralizing and monitoring privileged activities, such as patching, configuration, and troubleshooting

    Access through a jump host is usually limited to specific protocols (for example, SSH, RDP, or secure web interfaces) and may be combined with multi-factor authentication, session logging, and strict role-based permissions.

    Key characteristics

    • Network position: Placed at a boundary between security zones, often in a DMZ or dedicated access segment.
    • Hardened configuration: Reduced attack surface, restricted services, and tightly controlled user accounts.
    • Monitoring point: Commands, file transfers, and session activity can be logged for security, audit, and troubleshooting.
    • Limited purpose: Intended mainly for access mediation, not for running business applications or production workloads.

    Common confusion

    • Jump host vs. VPN: A VPN provides an encrypted tunnel into a network, while a jump host is a specific endpoint inside or at the edge of that network where users land and then pivot to other systems. They are often used together.
    • Jump host vs. bastion host: The terms are frequently used interchangeably. “Bastion host” is more common in security architecture diagrams, while “jump host” emphasizes the operational use as a stepping stone to other systems.
    • Jump host vs. remote desktop server: A remote desktop server delivers applications or desktops to users. A jump host may use remote desktop technology but is primarily a security control for mediated access.

    Operational relevance in manufacturing

    Within plants and regulated manufacturing environments, jump hosts are commonly used to separate corporate IT networks from OT networks that run production lines, utilities, or building management systems. They help enforce network segmentation, reduce direct exposure of equipment such as PLCs and SCADA servers, and centralize oversight of administrative and vendor access to critical systems.

  • cloud

    In industrial and manufacturing contexts, cloud commonly refers to computing services delivered over a network from shared, remotely hosted infrastructure instead of on local, on‑premise hardware. These services are typically provided by a third party and accessed via the internet or a private network.

    Core meaning

    Cloud usually includes three broad service models:

    • Infrastructure as a Service (IaaS): Virtual machines, storage, and networks hosted by a provider, used like remote data centers.
    • Platform as a Service (PaaS): Managed platforms for building, deploying, and running applications without managing servers directly.
    • Software as a Service (SaaS): Complete applications delivered via a browser or API, such as quality systems, asset management, or analytics tools.

    In regulated manufacturing and OT/IT environments, cloud services may host or process data related to production, quality, maintenance, or business planning, but the physical control of equipment typically remains on premises or at the edge.

    How it appears in operations

    • Data collection and historian offload: Sending production or sensor data from plant-floor systems or historians to a cloud environment for storage, reporting, or advanced analytics.
    • Manufacturing and quality applications: Using cloud-hosted MES modules, LIMS, QMS, OEE dashboards, or maintenance management systems accessed from multiple sites.
    • ERP and planning: Many ERP and supply chain systems are delivered as cloud services and exchange data with on-premise MES or OT systems.
    • Remote access to OT: Secure connectivity patterns where an OT zone communicates with a cloud service for monitoring, anomaly detection, or patch and configuration management.

    From a security and compliance perspective, many industrial standards and frameworks treat the cloud as another network zone or external system that must be risk-assessed, segmented, monitored, and governed. This includes defining data flows, access controls, and responsibilities between the manufacturer and the cloud provider.

    What cloud does not necessarily mean

    • It does not inherently mean that systems are public or unsecured. Private, community, and hybrid clouds are common in industrial use.
    • It does not automatically replace on-premise control systems. Critical OT control functions often remain local, with the cloud used for supervisory, analytical, or business functions.
    • It does not guarantee specific performance, resilience, or compliance characteristics. These depend on design, configuration, and contractual controls.

    Common confusion

    • Cloud vs. on-premise virtualization: A virtualized data center inside a plant is not typically called “cloud” unless it uses cloud-like service models (self-service, elastic scaling, metering).
    • Cloud vs. edge: Edge computing runs closer to equipment (for example, on gateways or industrial PCs). Edge systems may connect to the cloud but are distinct from the cloud itself.
    • Cloud provider vs. cloud service: A single provider can offer many distinct services (storage, messaging, analytics). Risk and integration considerations often apply at the individual service level, not only at the provider level.

    Link to OT cybersecurity standards context

    When industrial cybersecurity standards discuss cloud in relation to OT environments, they generally treat any cloud-hosted system as an external or separate zone. Cloud connections to control networks are typically subject to the same principles as other external connections: segmentation, least-privilege access, secure protocols, and documented governance for lifecycle management.
