  • Compensating control

    A compensating control is a security, quality, or compliance measure that is put in place to substitute for a required or preferred control when that original control cannot be fully implemented. The intent is to achieve a comparable level of risk reduction using an alternative approach that is feasible for the organization.

    In regulated industrial and manufacturing environments, compensating controls are often used when technical, operational, or legacy-system constraints prevent full implementation of a standard requirement. The alternative control must be documented, justified, and maintained so that it can be evaluated during internal reviews and external audits.

    Key characteristics

    Compensating controls typically:

    • Address the same risk as the original control, even if they work differently.
    • Provide comparable or stronger protection, not less.
    • Are specific and documented, including scope, responsibilities, and how effectiveness is verified.
    • Are time-bound or conditional in some programs, used until the primary control can be implemented.

    Examples in industrial and manufacturing settings

    • OT cybersecurity: If a legacy PLC cannot support strong authentication, a plant may implement strict network segregation, jump hosts, and monitored access logs as compensating controls for user-level access control on the device.
    • Electronic records and signatures: If an MES cannot yet enforce a specific electronic-signature workflow, a manufacturer may use controlled paper sign-off plus independent QA verification as a compensating control until the electronic workflow is enabled.
    • Physical access: If badge-based door control is not available for a critical area, a signed access log, key control process, and periodic supervisory checks may serve as compensating controls.

    Operational use

    From an operational standpoint, compensating controls are usually tied to risk assessments, change control, and deviation or waiver processes. Organizations commonly:

    • Identify a gap where a standard or policy requirement cannot be met.
    • Assess the associated risk and define one or more compensating controls.
    • Document the rationale, implementation details, and evidence to support audits.
    • Review effectiveness periodically and retire the compensating control if the primary control is later implemented.

    Common confusion

    Compensating control is commonly confused with:

    • Mitigating control: Both reduce risk, but in many frameworks a mitigating control is any additional control that lowers residual risk, while a compensating control is specifically an approved alternative to a defined requirement.
    • Temporary workaround: A workaround may restore operations but is not necessarily designed or justified to provide an equivalent level of risk reduction. Compensating controls are expected to be intentional, documented, and reviewable.

    Relation to standards and audits

    Many security, quality, and data-integrity standards recognize the concept of compensating controls, especially in areas like access control, segregation of duties, and electronic records. In practice, auditors and assessors will typically expect clear documentation explaining why the primary control is not used, how the compensating control works, and what evidence demonstrates that it manages the risk to an acceptable level.

  • asset

    An asset is any resource that has value to an organization and is deliberately managed over its lifecycle. In industrial and regulated manufacturing environments, this typically includes physical equipment, control systems, software, data, and supporting infrastructure that are required to produce, monitor, or verify products.

    Scope in industrial and OT/IT environments

    In operations and manufacturing, the term asset commonly includes:

    • Physical production assets such as machines, lines, robots, tools, test rigs, and utilities equipment.
    • OT and control assets such as PLCs, DCS components, sensors, actuators, industrial PCs, HMIs, field devices, and networking hardware.
    • IT and application assets such as servers, databases, MES, ERP, SCADA systems, historians, and specialized quality or labeling applications.
    • Information assets such as configuration data, production recipes, electronic batch records, specifications, software images, and firmware versions.

    An asset usually has an identifier, ownership, location, configuration, and defined responsibilities for maintenance, security, and change control.

    Operational meaning

    Operationally, assets are:

    • Tracked in CMMS, EAM, MES, or asset registers with status, usage, and maintenance history.
    • Controlled through change management, configuration management, and access control.
    • Assessed for risk, criticality, and impact on safety, quality, availability, and compliance.
    • Grouped into logical sets such as production cells, lines, or cybersecurity zones.

    In cybersecurity and standards such as IEC 62443, an asset is often a device, system, or application that must be identified, classified, and assigned to security zones and conduits. The same physical device may host multiple logical assets (for example, virtual machines or containers) that are treated and documented separately for security and compliance purposes.

    What an asset is not

    To avoid confusion, it is useful to distinguish assets from related concepts:

    • An asset is not the same as a process; processes use assets to transform inputs into outputs.
    • An asset is not necessarily a product; finished goods can be treated as inventory or commercial assets, but in operations the term usually refers to equipment, systems, and data used to make or control products.
    • An asset is not just a spare part; spare parts are usually managed as inventory that supports one or more assets.

    Common confusion

    • Asset vs. device: A device is a physical item, such as a PLC or sensor. An asset can be a device, but it can also be a software instance, data set, or virtualized host. One physical device can contain multiple logical assets.
    • Asset vs. configuration item (CI): In some IT service and configuration management practices, a CI is any component managed in the configuration management system. Many CIs are assets, but some CIs (such as low-level dependencies) may not be treated as standalone operational assets.
    • Asset vs. equipment: Equipment typically refers to physical machinery and tools. Asset is broader and includes software, information, and infrastructure.

    Tie to IEC 62443 context

    Within IEC 62443 and similar cybersecurity frameworks, an asset usually refers to any component in the industrial automation and control system that must be identified for risk assessment and zoning. A single physical device may be modeled as multiple logical assets (for example, separate virtual hosts or network interfaces) assigned to different zones, provided the separation, documentation, and controls are clearly defined and enforced.

  • How does Connect 981 ensure data privacy and security?

    “How does Connect 981 ensure data privacy and security?” is typically asked in the context of a specific industrial or manufacturing software product or integration layer called Connect 981. While details depend on the particular vendor implementation, in regulated manufacturing environments this question usually refers to how that system protects production, quality, and business data when it is collected, stored, transmitted, and integrated with other OT and IT systems.

    Typical privacy and security measures for a system like Connect 981

    In an industrial setting, a platform such as Connect 981 would commonly address data privacy and security through a combination of:

    • Secure communication: Use of encrypted network protocols to protect data in transit between shop floor equipment, MES/ERP, and other systems.
    • Access control: Role-based access, user authentication, and authorization so only approved personnel and services can access sensitive operational or quality records.
    • Data segregation: Logical separation of customers, plants, or product lines where needed to limit visibility of sensitive information and enforce need-to-know access.
    • Audit logging: Recording of configuration changes, user activities, and data access events for traceability and support of internal or external audits.
    • System hardening: Secure configuration, patching, and reduction of unnecessary services to limit attack surface in OT and IT environments.
    • Backup and recovery: Regular backups and tested restore procedures to protect data availability and integrity in case of failure or incident.
    • Governance and procedures: Documented policies for user management, data retention, and handling of regulated records, aligned with internal quality and IT/OT security requirements.

    Use in regulated manufacturing environments

    In regulated industries, a system like Connect 981 is often evaluated as part of the broader manufacturing IT/OT landscape. Organizations typically assess how it supports their own cybersecurity, data privacy, and quality governance programs, including:

    • Integration with existing directory services or identity providers for centralized user management.
    • Support for traceability of changes to production or quality data.
    • Controls that help keep technical data and export-controlled information appropriately restricted.

    Specific security guarantees, certifications, or compliance claims depend on the actual vendor and deployment and must be verified against that provider’s official documentation and an organization’s internal policies.

  • IEC 62443-3-3

    IEC 62443-3-3 is a standard within the IEC 62443 series that specifies system-level cybersecurity requirements for industrial automation and control systems (IACS). It focuses on what security capabilities an IACS or control system solution should provide, rather than how a specific technology must be implemented.

    What IEC 62443-3-3 covers

    IEC 62443-3-3 defines:

    • System security requirements for IACS components working together as a system, such as PLCs, DCS, SCADA, HMIs, historians, MES interfaces and related OT infrastructure.
    • Foundational requirements (FRs) that group security controls into categories such as identification and authentication control, use control, system integrity, data confidentiality, restricted data flow, timely response to events and resource availability.
    • Security levels (SLs) that describe increasing degrees of protection against threat actors with different capabilities and intent.
    • Mappings of requirements to SLs so that a system can be designed or assessed against a target security level for specific zones and conduits.

    In industrial and manufacturing environments, IEC 62443-3-3 is often used when specifying or evaluating control systems, OT networks and their interfaces to IT systems such as MES or ERP, to ensure appropriate cybersecurity capabilities are in place.

    How it is used operationally

    Operationally, IEC 62443-3-3 commonly appears in:

    • System design: Defining required security capabilities for new production lines, process control systems or site-wide OT networks.
    • Vendor and integrator requirements: Including specific IEC 62443-3-3 requirements in RFIs, RFPs or contracts for control systems, gateways and secure remote access solutions.
    • Risk and gap assessments: Comparing existing OT environments to IEC 62443-3-3 requirements to identify missing controls or weak security levels.
    • Zone and conduit modeling: Applying target security levels to defined zones (e.g., safety systems, production cells) and conduits (e.g., connections to MES, historian or cloud services).

    Relationship to the broader IEC 62443 series

    IEC 62443-3-3 sits in the “system” part of the IEC 62443 series. It is closely related to:

    • IEC 62443-1-x parts, which provide general concepts, terminology and models.
    • IEC 62443-2-x parts, which address policies, procedures and management aspects of IACS security.
    • IEC 62443-3-2, which describes risk assessment and the definition of zones and conduits that inform which IEC 62443-3-3 requirements and security levels are applicable.
    • IEC 62443-4-x parts, which define secure product development processes and technical requirements for individual components.

    Common confusion

    • IEC 62443-3-3 vs. IEC 62443 in general: IEC 62443-3-3 is one part of the overall IEC 62443 series. Saying a system is “IEC 62443 compliant” without specifying the part and scope can be ambiguous.
    • System-level vs. component-level: IEC 62443-3-3 focuses on system-level requirements. Component-level technical requirements are primarily addressed in IEC 62443-4-2.
    • Security level vs. safety integrity level: Security levels (SLs) in IEC 62443-3-3 are different from safety integrity levels (SILs) used in functional safety standards. They should not be conflated.

    Context in regulated manufacturing environments

    In regulated industries such as pharmaceuticals, food and beverage, medical devices and aerospace, IEC 62443-3-3 is often referenced when designing or assessing OT architectures that interact with quality systems, MES and data historians. Organizations may use it as a structured reference for defining control-system cybersecurity requirements aligned with internal risk management and applicable regulatory expectations, without implying or requiring any particular certification outcome.

  • System Security Plan (SSP)

    A System Security Plan (SSP) is a formal document that describes how security requirements are implemented, managed, and maintained for a specific information system or environment. In regulated and industrial settings, it is typically used to document how a manufacturing, OT, MES, or related IT system meets defined cybersecurity and compliance requirements.

    What a System Security Plan includes

    While formats vary by framework and organization, an SSP commonly documents:

    • System description and boundaries: Purpose, functions, system components, data flows, and connections to other systems or networks, including OT/IT interfaces.
    • Applicable security requirements: Referenced standards or frameworks (for example, NIST SP 800-53, NIST SP 800-171, or corporate policies).
    • Control implementation details: How each required control is implemented or addressed, including technical, administrative, and physical safeguards.
    • Roles and responsibilities: Who is responsible for implementing, operating, and monitoring each control, including shared responsibilities with cloud or service providers.
    • System environment and dependencies: Operating systems, applications, cloud services, OT equipment, and supporting infrastructure the system relies on.
    • Configuration and baseline information: References to secure configurations, hardening guides, or baseline settings relevant to the system.
    • Continuous monitoring and maintenance: How security is monitored, how changes are controlled, and how issues are tracked and remediated.

    Use in regulated manufacturing environments

    In manufacturing and industrial operations, a System Security Plan commonly applies to:

    • Manufacturing execution systems (MES) and production control systems.
    • OT networks, SCADA/PLC environments, and data historians.
    • Quality and laboratory systems (for example, LIMS, QMS platforms).
    • Cloud-hosted applications supporting production, quality, or supply chain processes.

    Organizations use SSPs to demonstrate how security controls are applied in practice, to support audits and assessments, and to coordinate security responsibilities among internal IT/OT teams, vendors, and cloud providers.

    Relationship to frameworks like NIST SP 800-53

    In the context of NIST-based programs, the SSP is the central document that maps required controls (for example, those derived from NIST SP 800-53) to specific implementations in the system. When cloud or external providers are involved, the SSP typically:

    • Identifies which controls are implemented by the provider.
    • Identifies which controls are shared and require customer configuration.
    • Identifies which controls remain entirely the responsibility of the organization operating the manufacturing or OT system.

    The SSP often references provider documentation such as security packages, control responsibility matrices, and configuration baselines, but it remains the organization’s document that describes the end-to-end system.

    Common confusion

    • Not just a policy document: An SSP is more detailed and system-specific than a high-level security policy. It focuses on how controls are applied to a particular system or environment.
    • Not a certification: An SSP by itself does not indicate certification or approval. It is an input to assessments, authorizations, or audits.
    • Not a vendor security whitepaper: Vendor or cloud security documentation can be referenced in an SSP, but does not replace the need for an SSP that covers the complete system boundary and local responsibilities.

    Operational role

    Operationally, a System Security Plan serves as a reference for:

    • Onboarding new team members to the security characteristics of a production or OT system.
    • Planning and documenting security changes or upgrades.
    • Supporting internal reviews, risk analyses, and external audits of manufacturing and quality systems.
    • Coordinating with vendors and service providers on shared security responsibilities.
  • authorization

    Authorization is the decision and process that determines what actions a user, system, device, or service is allowed to perform within an information system or operational environment after its identity has been authenticated.

    Core meaning in industrial and regulated environments

    In manufacturing, OT, and regulated IT systems, authorization commonly refers to:

    • Defining which roles, users, applications, or equipment may access specific data, functions, or physical assets
    • Configuring and enforcing access control rules (for example, view-only vs. edit vs. approve)
    • Recording decisions that a connection, transaction, or command is allowed to proceed

    Authorization typically builds on authentication (verifying who or what is requesting access) and is implemented through mechanisms such as role-based access control (RBAC), attribute-based access control (ABAC), and network or firewall rules.

    Operational context

    In industrial and compliance-driven settings, authorization shows up in several ways:

    • Application and MES permissions: Controlling who can release production orders, modify recipes, change batch records, or close quality events.
    • System-to-system access: Allowing specific services, such as an MES, historian, or ERP integration service, to read or write particular data sets or APIs.
    • Network and OT security: Determining which devices or segments may communicate, and under what conditions, especially when connecting plant systems to cloud services.
    • Approval workflows: Enforcing that only authorized roles can approve deviations, CAPAs, engineering changes, or document releases.

    Authorization in compliance frameworks (including FedRAMP / NIST)

    In cybersecurity and regulatory frameworks, the term is also used more formally:

    • Access authorization: Technical and procedural controls that ensure only authorized accounts and services can use a system or data set, as described in many NIST SP 800-53 control families.
    • System authorization: A management decision that a system or cloud service is approved to operate within a defined risk posture, often documented as an authorization to operate (ATO). FedRAMP and similar programs use this concept to indicate that a cloud service has been assessed against a defined control baseline.

    In plant or enterprise contexts, access authorization is relevant to user and service permissions, while system authorization (such as a cloud provider’s ATO) is a higher-level management determination and does not by itself ensure compliance across local OT or manufacturing environments.

    What authorization is not

    • It is not identity verification itself; that is authentication.
    • It is not a guarantee of regulatory compliance; it is one element of a broader control and governance framework.
    • It is not the same as accounting, audit logging, or traceability, although those may record authorized actions.

    Common confusion

    • Authorization vs. authentication: Authentication confirms who or what is requesting access. Authorization decides what that authenticated entity is allowed to do.
    • Authorization vs. approval signatures: In quality and document control workflows, electronic signatures may represent approval or sign-off. These signatures rely on underlying authorization rules but are not the authorization logic itself.
  • hardening

    Hardening commonly refers to the process of reducing the attack surface of a system, device, application, or network by configuring it in a more secure state. In industrial and manufacturing environments, hardening focuses on operational technology (OT) assets, industrial control systems (ICS), supporting IT infrastructure, and related software used in production, quality, and maintenance.

    Core meaning in industrial and OT contexts

    In regulated industrial environments, hardening typically includes:

    • Disabling unnecessary services, ports, and protocols on controllers, servers, workstations, and network devices
    • Configuring secure defaults for operating systems, PLCs, HMIs, historians, MES, and related components
    • Enforcing authentication, authorization, and role-based access controls
    • Applying secure network architecture concepts such as segmentation, zoning, and controlled remote access
    • Configuring logging, time synchronization, and monitoring to support detection and investigation
    • Setting secure parameters for encryption, key management, and certificate handling where supported
    • Documenting environment assumptions and constraints that the configuration relies on

    Hardening is normally performed according to internal security policies, industry guidance (for example, ICS security guidelines), or structured frameworks such as those aligned with IEC 62443. For components advertised as security-aligned, suppliers are often expected to provide hardening guides and configuration recommendations that asset owners can implement and validate.

    Operational role

    In day-to-day operations, hardening appears as:

    • Standard build images and baseline configurations for engineering workstations, servers, and operator stations
    • Commissioning and change-control steps that ensure new or modified assets are configured in line with approved security baselines
    • Periodic reviews to confirm that hardening settings remain in place and compatible with production needs
    • Documentation that describes intended use, security-relevant settings, and any functions that must remain disabled in validated or regulated environments

    Hardening is not a one-time activity. It typically interacts with patching, system upgrades, and process changes, and it must be kept consistent with validation, qualification, and documentation requirements in regulated plants.

    Common confusion

    Hardening vs. patching: Hardening adjusts configuration and design to limit exposure; patching updates software or firmware to correct defects or vulnerabilities. Both are security controls but address different aspects.

    Hardening vs. secure coding or design: Secure development practices aim to prevent vulnerabilities in the first place. Hardening assumes the component already exists and focuses on how it is deployed and configured.

    Hardening in materials science: In metallurgy or materials engineering, hardening can refer to increasing the hardness of a material through heat treatment or work processes. In the context of industrial cybersecurity and systems, the term almost always refers to security hardening of digital or networked assets.

    Link to IEC 62443-aligned documentation

    For components intended to align with IEC 62443, asset owners often expect supplier documentation that explicitly covers hardening. This typically includes recommended secure configurations, assumptions about the operating environment, dependencies on other security controls, and guidance on how to maintain the hardened state over the component lifecycle.

  • DMZ (Demilitarized Zone)

    A DMZ (Demilitarized Zone) in networking is a controlled network segment that sits between an internal network and an external or less trusted network, such as the public internet or a partner network. It is used to host systems that must be reachable from outside while limiting direct access to critical internal systems.

    What a DMZ includes

    In industrial and manufacturing environments, a DMZ commonly refers to one or more network zones that:

    • Separate operational technology (OT) networks, such as control systems and PLCs, from information technology (IT) networks and the internet
    • Host intermediary systems like jump servers, proxy servers, historians, application gateways, remote access gateways or edge nodes
    • Apply strict, rules-based traffic control using firewalls, gateways, and monitoring tools

    The DMZ is designed so that if a system in the DMZ is compromised, the attacker does not gain unrestricted access to internal business or control networks.

    What a DMZ does not include

    • It is not the core internal network where business applications, MES, ERP, and controllers normally reside.
    • It is not a single product; rather, it is a network design pattern that uses multiple technologies (firewalls, routing rules, proxies, authentication services).
    • It is not the same as simple port forwarding or a flat network segment with no access controls.

    DMZ in OT/IT manufacturing environments

    In regulated and industrial settings, DMZs are often used to manage data exchange and remote access between plant-floor systems and corporate or external services. Examples include:

    • Placing an industrial historian or data broker in a DMZ between Level 3 (site operations) and enterprise IT networks to transfer production data
    • Using a remote access gateway in a DMZ to allow vendors to service equipment without direct access to control networks
    • Locating web front-ends, APIs, or file transfer services that must be reachable from outside partners but that only expose tightly controlled interfaces to internal MES or quality systems

    Designs often align with recognized reference models for industrial control system segmentation, with separate firewalls and security policies on each side of the DMZ.

    Operational considerations

    In practice, managing a DMZ involves:

    • Defining which services and protocols are allowed in and out, and from which source and destination networks
    • Monitoring traffic and system logs for unusual activity
    • Keeping DMZ systems hardened and updated separately from both internal and external networks
    • Documenting data flows across the DMZ, especially where regulated data, audit trails, or electronic records are involved

    Common confusion

    • DMZ vs. VLAN: A VLAN is a logical network segmentation method. A DMZ is a security architecture concept that may use VLANs, but also requires firewalling, routing, and access control policies.
    • DMZ vs. firewall: A firewall is a device or service enforcing traffic rules. A DMZ is the network zone created and protected by those rules.
    • DMZ vs. air gap: A DMZ still allows controlled connectivity. An air-gapped system is physically or logically isolated with no routine network connection.

    Relation to regulated manufacturing

    Within regulated manufacturing, DMZs are commonly used to control how production data, batch records, quality data, or equipment configurations move between plant systems and enterprise or cloud services. Clear separation and documentation of DMZ traffic paths can support cybersecurity programs and audit readiness.

  • CSF

    CSF most commonly refers to the NIST Cybersecurity Framework, a risk-based framework for managing cybersecurity. It provides a structured way for organizations, including those operating industrial and regulated manufacturing environments, to describe, assess, and improve their cybersecurity posture.

    What the CSF is

    The NIST Cybersecurity Framework (CSF) is a set of high-level cybersecurity functions, categories, and outcomes that help organizations:

    • Identify critical assets, systems, data, and business processes
    • Protect those assets with appropriate safeguards and controls
    • Detect cybersecurity events in a timely manner
    • Respond to incidents to contain impact
    • Recover to normal operations and improve future resilience

    In industrial and manufacturing settings, CSF is often applied across both IT and OT environments, covering systems such as MES, SCADA, PLC networks, plant historians, quality systems, and ERP interfaces.

    How CSF is used operationally

    In practice, organizations use the CSF to:

    • Define a common cybersecurity vocabulary between IT, OT, engineering, and management
    • Map existing controls (for example, NIST SP 800-53, IEC 62443, or internal policies) to CSF outcomes
    • Assess current cybersecurity posture and identify gaps in controls for production and support systems
    • Prioritize cybersecurity activities and roadmaps for plants, laboratories, and corporate environments
    • Align cyber risk discussions with business continuity and safety considerations

    Organizations often maintain internal mappings between CSF outcomes and specific technical and procedural controls, such as access control configurations on MES/SCADA, change management workflows, backup and recovery procedures, and vendor remote access oversight.

    Common confusion

    The abbreviation CSF can refer to different concepts in other domains, which can cause confusion:

    • NIST Cybersecurity Framework (CSF) is the relevant meaning for industrial cybersecurity and compliance topics.
    • Critical Success Factor is a business and project management term unrelated to NIST cybersecurity content.

    In the context of cybersecurity, OT security, and mappings to NIST SP 800-53, CSF should be understood as the NIST Cybersecurity Framework.

    Relation to NIST SP 800-53 and other standards

    The CSF is a framework for outcomes and functions, not a detailed control catalog. For detailed security controls, organizations often reference NIST SP 800-53 or other control sets and then map those controls to CSF outcomes. Official and community mappings are commonly published to help relate CSF categories and subcategories to 800-53 controls and other standards. These mappings support alignment work but do not replace site-specific risk analysis, control tailoring, or validation in a plant or manufacturing environment.
