Secure ION security certificates
Devices that support Secure ION include a self-signed SSL certificate. When you connect to a device using Secure ION, a certificate must be associated with the TLS connection.
You can upload a Certificate Authority (CA) signed certificate. For details, see Uploading a custom SSL certificate.
NOTE: To reduce cybersecurity risk, use a Certificate Authority (CA) signed SSL certificate and external network controls. To learn more about this risk, see Security risks and mitigation strategies.
In ION Setup, you can view the certificate information—including its SHA1 thumbprint—by clicking View Certificate Info.
For example:
ION Setup stores the certificate when using Network mode. In Single Device mode, you must accept the certificate every time you connect to a device using Secure ION.
