Secure Deployment Best Practices for Handpunch Network Manager
1. Plan network segmentation
- Isolate biometric devices and the Handpunch server on a separate VLAN/subnet.
- Restrict inter-VLAN access with firewall rules allowing only necessary management and data flows (e.g., server ↔ devices, admin workstations ↔ server).
2. Harden the server OS
- Minimal install: run only required services.
- Patching: enable automatic or regular patching for OS and dependencies.
- Account hygiene: remove or disable unused accounts; enforce strong, unique admin passwords.
- Least privilege: run the Handpunch service under a dedicated, low-privilege account.
3. Secure device configuration
- Change default credentials on all Handpunch devices and management interfaces.
- Disable unused services and ports on devices.
- Firmware updates: keep device firmware current with tested updates.
4. Use strong authentication and access control
- Multi-factor authentication (MFA): enforce for administrative access where supported.
- Role-based access control (RBAC): limit who can view, configure, or export data.
- Audit logging: enable and centralize logs for authentication, configuration changes, and data exports.
5. Encrypt data in transit and at rest
- TLS: enable HTTPS/TLS for web/management interfaces and encrypted device-server communications if supported.
- Network encryption: use IPsec or VPN for remote sites.
- At-rest encryption: encrypt databases and backups containing personally identifiable or biometric data.
6. Protect biometric and personal data
- Data minimization: store only required fields and retain for the minimum needed period.
- Template security: store biometric templates (not raw images) and protect them with encryption and access controls.
- Anonymization/pseudonymization: where possible, separate identifiers from biometric data.
7. Backup and recovery
- Regular backups: schedule encrypted backups of configuration and databases.
- Test restores: verify backups periodically to ensure recovery procedures work.
- Offline copies: keep at least one encrypted offline backup to protect against ransomware.
8. Network and host monitoring
- Intrusion detection: deploy IDS/IPS or network monitoring to detect anomalous device or server behavior.
- Endpoint protection: run vetted anti-malware and EDR on the server and admin workstations.
- Health checks: monitor device connectivity, sync status, and clock drift.
9. Secure integrations and APIs
- Least-privilege service accounts for integrations (payroll, HR).
- API keys/tokens: rotate regularly and store secrets in a vault.
- Input validation and rate limiting on integration endpoints.
10. Physical security
- Restrict physical access to the Handpunch server and devices.
- Tamper detection: enable device tamper alerts where available.
- Secure mounting and cabling to prevent easy removal or tampering.
11. Policies, training, and compliance
- Acceptable use and data handling policies for biometric systems.
- Staff training on secure administration, incident response, and privacy obligations.
- Regulatory alignment: ensure deployments meet relevant laws (e.g., GDPR, CCPA) and industry standards.
12. Incident response and testing
- IR plan: include steps for device compromise, data breach, and ransomware.
- Tabletop exercises: run scenarios annually or after major changes.
- Forensics readiness: maintain logs and secure preserves for investigations.
