Connected Injection Pen Cybersecurity: An OEM Checklist

Reviewed November 6, 2026 · For B2B procurement and development teams

Key parameters to define

• System boundary and protected assets
• Threat model and safety impact
• Authentication, authorization and key management
• Secure update and rollback behavior
• Software dependency and SBOM controls
• Vulnerability handling and incident response
• Support period and service retirement plan

Define the security boundary and assets

List every component that stores, processes or transmits data: sensors, microcontroller, local memory, NFC or Bluetooth interface, mobile application, software development kits, cloud services, portals, APIs and update infrastructure. Identify which data and functions require protection, who can access them and what harm could result from loss of confidentiality, integrity or availability. The threat model should include unauthorized pairing, spoofed devices, altered records, replayed messages, credential compromise, vulnerable dependencies, insecure updates and service outages. The device architecture must distinguish safety-critical controls from convenience functions and define a safe state when connected services are unavailable. This system map is the basis for requirements, testing, supplier agreements and the evidence package. Document the decision, evidence status, responsible owner and unresolved assumptions so later project changes can be reviewed against a stable baseline.

Build security into development and verification

Security requirements should cover identity, authentication, authorization, least privilege, secure communication, key handling, software integrity, logging, dependency management and update authenticity. Verification needs negative and misuse cases, not only successful connection tests. Document how development tools, third-party libraries and software bills of materials are controlled. Pairing and recovery workflows must also be usable by the intended population; a secure design that routinely drives users to bypass controls is not robust. Testing scope should reflect the exact architecture and interfaces, and findings need documented risk evaluation and closure. If a platform is modified for a customer, the parties should determine whether prior security evidence still applies or whether the change creates new threats or verification needs. Write acceptance criteria before testing so observations remain traceable to an approved requirement rather than being interpreted only after the result.

Plan post-market maintenance before launch

A connected system needs named owners for vulnerability intake, monitoring, triage, coordinated disclosure, patches, cloud maintenance, mobile operating-system changes, end-of-support communication and incident response. Contracts should state which party maintains firmware, the app, backend services, certificates, developer accounts and third-party integrations. Define how long components will be supported, how users receive updates, what happens when an update fails and how safety is preserved if a service is retired. FDA’s current guidance treats cybersecurity as part of device design and quality-system work for devices with cybersecurity risk. A credible OEM proposal therefore includes lifecycle staffing and maintenance assumptions rather than presenting security as a one-time penetration test at the end of development. Record the output, approval owner and change triggers in the project file so procurement, engineering, quality and regulatory teams use the same baseline.
