What to do
AI-suggested
- Enforce strict physical security controls around HSM devices, including secure access areas, surveillance, and tamper-evident seals to prevent unauthorized physical proximity.
- Limit and monitor privileged user access to the HSMs, employing role-based access control and multi-factor authentication to reduce risk of insider threats.
- Implement continuous monitoring and alerting for anomalous tamper events or unusual device behavior that could indicate exploitation attempts.
- Segregate HSMs from general network access where possible, using dedicated management networks to reduce attack surface.
- Maintain an inventory of all Entrust nShield devices and firmware versions to identify affected units.
- Engage with Entrust support for timely updates and patches as they become available, and plan for rapid deployment.
- Conduct regular security audits and penetration testing focusing on physical security and HSM integrity.
- Develop incident response plans specifically addressing HSM compromise scenarios to minimize impact if exploitation occurs.
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 a physically proximate attacker with elevated privileges to falsify tamper events by accessing internal components.
