Intro
Modern devices, ranging from servers to IoT sensors, operate on firmware that, if compromised, allows attackers to maintain a presence below the OS.

NIST SP 800-193 outlines practical resiliency:
Protect, detect, recover.
DNSystems LLC transforms that guidance
into .............................
Quick,actionable services to ensure your fleet remains trustworthy and repairable.

Why it matters
Firmware lives below traditional defenses and is persistent—so breaches can be long‑lived and hard to fix.
Critical infrastructure, industrial controls, & enterprise endpoints
depend on firmware integrity for uptime, safety, and compliance.
A resilient firmware strategy reduces downtime, supply‑chain risk, &
expensive emergency recoveries.

What DNSystems LLC delivers
Firmware Resiliency Assessment: inventory firmware (BIOS/UEFI, BMC, EC, option ROMs), threat mapping, prioritized heatmap and remediation roadmap.
Secure Update & Recovery Design: authenticated, atomic update flows with rollback protection and redundant images to prevent bricking and supply‑chain attacks.
Measured Boot & Attestation Integration: TPM‑backed measurements, remote attestation, and SIEM integration so you detect integrity drift quickly.
Recovery Automation & Runbooks: tested fallback images, automated recovery procedures (local and remote), and incident playbooks to restore service fast.
Procurement & Vendor Requirements: contract language & technical specs to demand
signed firmware, immutable roots of trust, and secure provisioning from suppliers.
Firmware Penetration Tests & Validation: hands‑on testing of update paths,
signature enforcement, and protective hardware to verify real‑world resiliency.
Quick wins for clients
Enforce firmware signing and disable unsigned update channels.
Enable TPM/secure boot measurements and forward logs to monitoring.
Add a protected fallback image and validate automated recovery.
Include firmware checks in CI before deployment.
Why choose DNSystems LLC
Practical, vendor‑agnostic engineering from contract to Continuous Integration (CI).
Focus on automation so resiliency scales across fleets.
Deliverables: inventory + heatmap, remediation roadmap, implementation guides, recovery playbooks.
