Preventing unauthorized firmware rollbacks is critical for maintaining device security and functionality. Here are the best strategies to safeguard against such threats:

1. Implement Secure Boot Mechanisms: Ensure devices only boot with signed, verified firmware to block unauthorized rollbacks.

2. Enforce Version Control Policies: Use firmware version checks to prevent downgrades to vulnerable versions.

3. Utilize Cryptographic Signatures: Require digital signatures for all firmware updates to verify authenticity.

4. Enable Tamper Detection: Integrate hardware-based tamper detection to alert or block unauthorized changes.

5. Regular Firmware Audits: Conduct periodic audits to identify and patch vulnerabilities in firmware updates.

By adopting these measures, organizations can mitigate risks and maintain robust firmware security.
