IEC 62443 Firmware Security Review (Practical)

Description

This security review is for industrial device manufacturers, IoT product teams, and embedded startups who need to understand and reduce firmware security risk—without drowning in compliance paperwork.

If you’re asking:

• Where are our real firmware attack surfaces?

• Are debug ports, credentials, or update paths exposing us?

• What should we fix first—and why?

This service gives you practical security clarity, not theory.

What You Get

✔ Threat model (IEC 62443-aligned)
Clear identification of assets, attackers, entry points, and trust boundaries relevant to your firmware and deployment context.

✔ Findings & risk report
Actionable list of security findings with severity, impact, and concrete remediation guidance—prioritized by real-world risk.

✔ Secure boot & OTA recommendations
Practical guidance for boot chain integrity, firmware authenticity, and update safety (vendor-agnostic).

✔ Credential storage & debug lockdown plan
Recommendations for key handling, secrets storage, debug interface hardening, and production lock-down.

✔ Security checklist for future releases
Reusable checklist your team can apply to future firmware versions to prevent regression.

Scope (What’s Included)

• Firmware-focused security review

• Static and architectural analysis (not penetration testing)

• IEC 62443 concepts applied practically

• Device-side security (MCU / SoC / embedded Linux)

Formal certification, lab testing, or full red-team exercises are out of scope and handled separately.

• Threat model documented and explained

• Security findings prioritized and justified

• Clear remediation actions defined

• Hardening recommendations delivered

• Reusable security checklist provided
