What to do
AI-suggested
- Immediately review and enhance physical security controls around Entrust nShield HSM devices to prevent unauthorized local access, including secure server rooms, surveillance, and access logging.
- Check if the affected HSM firmware versions support BIOS password configuration; if so, enable strong BIOS passwords to restrict unauthorized BIOS access.
- Monitor HSM device logs and physical access logs for any suspicious activity or unauthorized access attempts.
- Segregate HSMs in isolated network segments with strict access controls to limit exposure.
- 6. Implement strict insider threat detection and response programs to mitigate risks from authorized personnel misuse. 7. Conduct regular security audits and penetration tests focusing on physical and firmware security of HSMs. 8. Develop incident response plans specifically for HSM compromise scenarios, including key revocation and re-issuance procedures. 9. Consider deploying additional layers of cryptographic key protection, such as multi-factor authentication for key usage or hardware-based tamper detection. 10. Document and enforce policies requiring immediate reporting and investigation of any physical or configuration anomalies related to HSM devices.
Description
Entrust nShield Connect XC, nShield 5c, and nShield HSMi through 13.6.11, or 13.7 (patched in 13.6.12 (LTS) and 13.9.0 (STS)), allow an attacker to gain access the the BIOS menu because is has no password.
