Secure Embedded Systems

Secure embedded platforms for fielded and regulated devices.

RTG helps teams harden embedded platforms, verify releases, control updates, generate cybersecurity evidence, and reduce risk before devices reach the field.

Security Engineering

Security controls that engineering and release teams can actually operate.

Secure embedded systems require practical implementation: boot trust, signed packages, controlled update authorization, least-functionality configuration, dependency tracking, release verification, and recovery paths. RTG focuses on controls that can be built, tested, documented, and supported.

Common Needs

Secure boot, signed images, verified packages, and PKI-backed update authorization
SBOM generation, vulnerability review, dependency tracking, and release evidence
USB/device control, service restrictions, least-functionality configuration, and hardening
A/B updates, rollback plans, recovery partitions, and integrity verification

Evidence

Security work should leave behind reviewable proof.

Architecture Evidence

Security design descriptions, update architecture, recovery behavior, platform boundaries, and verification strategy.

Release Evidence

Build manifests, SBOMs, package lists, dependency checks, integrity verification, and release-control records.

Verification Evidence

Test procedures, pass/fail records, update validation, rollback validation, and failure-mode documentation.

Regulated Evidence

Threat modeling, traceability, cybersecurity documentation, RCA/CAPA support, and technical content for customer-led review processes.

Where It Applies

Medical, mission, RF, and connected systems all need secure transition paths.

Secure embedded engineering is a common thread across RTG practices: medical-device cybersecurity, connected-device field support, RF sensing nodes, and defense-oriented prototypes all need dependable update paths, release evidence, and controllable platform behavior.
