Introduction

The rising connected packaging landscape

Packaging equipment now often connects to digital networks. IIoT-enabled components, smart sensors, and cloud storage are common in modern lines. This connectivity improves efficiency but also widens the attack surface.

Industry players like Robopac USA and Aetna Group illustrate the shift toward automation and remote monitoring. As packaging systems grow more automated, reliable data flows become essential, bringing both opportunities and cyber risk that must be managed thoughtfully.

Why cybersecurity matters for packaging operations

Cyber threats targeting packaging can disrupt production and compromise data. Securing equipment supports continuity and protects sensitive information. A strong cybersecurity posture helps prevent tampering and unauthorized access.

ISO/IEC 27001 provides a formal framework for information security management, helping packaging operations demonstrate ongoing risk management, data protection, and supplier assurance within connected lines. HMC Products provides packaging automation solutions that align with these security goals, offering equipment with built-in security features and transparent firmware updates to reduce risk across the line. Informa connects packaging security insights, including market intelligence and events, to help you align governance and supplier risk programs with industry best practices.

Practical steps can yield meaningful protection. Grounding your approach in people, processes, and technology creates a balanced defense. Treat cybersecurity as part of digital transformation, not an afterthought.

Secure Remote Access and Maintenance for Packaging Equipment

Best practices for remote maintenance access

You enable remote maintenance to keep lines running without compromising security. Start with a formal access policy that defines who can reach equipment, when, and for what purpose. Use multi factor authentication to verify identities before any session begins.

Isolate remote sessions from the production network. Favor jump hosts or secure gateways that centralize control and auditing. Record session activity to support forensics and compliance reviews. Establish clear approval workflows for maintenance windows and changes to equipment.

• Use role-based access control to limit what each technician can do on a device.
• Require unique credentials for every technician and avoid shared accounts.
• Implement session hardening to prevent command history leakage and screen capture.
• Deploy network access controls that restrict connections to approved endpoints only.

Zero trust and least privilege in OT environments

Adopt zero trust to verify every access attempt, regardless of origin. Continuous authentication and device posture checks reduce risk from compromised credentials.

Apply least privilege by limiting user actions to only those necessary for the task. Regularly review permissions as roles evolve with maintenance needs.

• Segment remote access by device class (packers, palletizers, casers) to constrain blast radii.
• Enforce time bound and scope restricted sessions tied to specific maintenance tasks.
• Monitor ongoing sessions for unusual commands or anomalous data transfers.

Endpoint and Device Hardening for IoT Packaging Components

Firmware integrity and secure boot

Endpoint security starts with trustworthy firmware. Verified boot ensures the device only runs code that is signed by the manufacturer, preventing tampered firmware from taking control.

Implement measures that include firmware signing, secure boot chains, and runtime integrity checks that alert you to any unexpected changes during operation.

• Verify firmware signatures at each update before installation
• Enforce hardware backed key protection to prevent key extraction
• Use tamper evident logs to track firmware events across endpoints

Regular patching and vulnerability management

Maintenance cycles must address known weaknesses without disrupting production. A disciplined patching approach reduces exposure while preserving line uptime.

Establish a routine for monitoring, testing, and deploying updates across all connected packaging components to close gaps promptly.

• Schedule non disruptive patch windows aligned to maintenance cycles
• Prioritize high risk CVEs that affect OT protocols and device firmware
• Maintain an asset inventory to track affected endpoints and verify remediation

Network Segmentation and Secure Communications in Packaging Plants

Segmentation to limit lateral movement

Segmentation confines access so a breach in one area cannot easily spread. Model the plant as distinct zones to enforce clear data flows and access boundaries between packaging equipment, controls, and enterprise IT.

Perimeter controls should shield critical assets such as palletizers, depalletizes, packers, and CI systems. Use firewalls, access controls, and network policies to restrict traffic between zones to what is necessary for operation and maintenance.

• Define device classes and assign them to dedicated segments
• Apply micro-segmentation to control east west traffic at the device level
• Regularly audit inter-zone communications for deviations

Encryption in transit and secure protocols for Industrial IoT

Protect data as it moves across the production floor and toward cloud or on-premise analytics. Encryption in transit reduces the risk of eavesdropping, tampering, and impersonation.

Adopt secure OT appropriate protocols and ensure protocol hardening across IIoT components. Centralized key management and rotation help maintain trust across the network.

Aspect	Guidance
Segmentation scope	Zone by zone design for critical packaging equipment
Traffic controls	Least privilege access and explicit allowlists between zones
Encryption	TLS for device communications; strong cipher suites

Threat Detection and Incident Response for Connected Packaging

Monitoring and anomaly detection in OT

Maintain real time visibility across packaging lines to detect deviations early. Focus on unusual device behavior, throughput shifts, and configuration changes that diverge from established baselines.

Adopt a layered detection approach that blends signature-based alerts with behavior analytics. Correlate data from sensors, PLCs, HMI, and IIoT devices to spot subtle indicators of compromise before they escalate.

• Centralized dashboards that map equipment health to security events
• Automated alerting for deviations in cycle times, tolerances, and command sequences
• Baseline models updated to reflect seasonal production changes and maintenance windows 

Incident response playbooks tailored to packaging environments

Design playbooks around the rhythms of packaging operations, including shift changes and planned maintenance. Define clear roles, communication paths, and predefined recovery steps.

Structure playbooks to address common incident types such as unauthorized remote access, firmware tampering, and service disruption. Include containment, eradication, and recovery steps that minimize downtime.

• Containment steps that isolate affected zones without stopping entire lines
• Eradication goals that remove footholds and verify device integrity
• Recovery actions with verified restoration of production continuity and data integrity

Aspect	Guidance
Detection sources	OT telemetry, device logs, network flow data
Response targets	Quick containment, minimal downtime, verifiable restoration
Communication	Predefined escalation paths and incident status updates

Data Protection, Privacy, and Supply Chain Security

Encrypting sensitive production and customer data

Protecting sensitive information is essential to maintain trust and compliance. Encryption at rest and in transit helps ensure that data remains unreadable to unauthorized parties across the packaging workflow.

Apply standardized encryption approaches across the IIoT network and cloud connections. This includes protecting customer data, production metrics, and configuration logs from exposure or tampering.

• Implement AES-256 or equivalent strong encryption for stored data
• Use encryption for data in transit between devices, gateways, and cloud services
• Centralize key management with rotation policies and access controls

Third-party risk management for packaging partners

Suppliers and service providers expand the security surface. A formal third-party risk program helps identify, assess, and mitigate potential weak points in the supply chain.

Adopt a structured approach to evaluate vendor cybersecurity postures, incident history, and data handling practices before integration with packaging equipment or automation stacks.

• Require security questionnaires and routine audits for critical partners
• Mandate secure software supply chain practices, including verified firmware sources
• Integrate partner risk findings into your risk register and remediation plans

Aspect	Guidance
Data protection	Encrypt sensitive data at rest and in transit; manage keys securely
Privacy compliance	Align with applicable data protection regulations and retention policies
Supply chain	Assess and document vendor security postures; enforce secure software practices
