A signed firmware image does not guarantee a secure boot process. Rollback, interrupted updates, exposed debug access, compromised keys, and fault injection can defeat designs that appear secure on paper.
In this 60-minute technical webinar, see how these attacks reach the boot chain, where common defenses fall short, and how to design for prevention, detection, recovery, and attestation. Three live wolfBoot demonstrations will show tamper and downgrade protection, interrupted-update recovery, and device attestation in practice.
You’ll learn how to:
- Map attack paths through a minimal secure boot chain
- Stop tampered or downgraded firmware from running
- Recover safely from interrupted firmware updates
- Lock down debug access and harden verification against fault injection
- Choose an appropriate root of trust, isolation model, and attestation strategy
Ask the Expert: Answers Key Questions
Our experts answer key questions about what attendees will learn
Why isn’t firmware signature verification enough?
A signature confirms that firmware came from a trusted signing key and has not been modified. Without additional defenses, the device may still accept older signed firmware or have verification bypassed through compromised keys, exposed debug access, or fault injection.
How should the boot process respond to an attack or failed update?
It must reject unauthorized or downgraded firmware while preserving a known-good image. If an update is interrupted, the device must recover without bypassing its security policy or becoming unbootable.
How do the root of trust and firmware policy shape the design?
The root of trust defines where verification begins, while the lifecycle and downgrade policy determine which signed firmware the device may run. Debug lockdown, hardware isolation, recovery, and attestation must support those decisions without creating another path around them.
