General Security Recommendations
To ensure a secure operating posture for your multifunction devices, and to reduce exposure to the vulnerabilities described in this advisory, Konica Minolta strongly recommends applying the following configuration best practices:
1. Avoid Direct Internet Exposure
Place devices behind firewalls and use private IP addressing and Device IP Filtering settings.
2. Change Default Passwords
Change default credentials and implement strong passwords for administrative and network functions.
3. Use Strong Passwords for Services
Ensure strong credentials are configured for SMTP, LDAP, SMB, WebDAV, and any other integrated services.
4. Disable Unused Services
Turn off unused ports or protocols to reduce attack surface.
5. Use Secure Protocols
Configure devices to use encrypted communications (e.g., HTTPS, LDAPS, IPPS) where supported.
6. Monitor Device Activity
Regularly review device logs and network traffic for suspicious behaviour.
7. Enable Authentication Where Available
Use built-in user authentication features to prevent unauthorised access to device functions.
For comprehensive information on secure configuration, please refer to our Product Security web site.
