Article summary

A TLS certificate is a digital credential that ensures secure communication by encrypting data exchanged between the connected clients to the CTERA Edge Filer.

A customer that uses a privately issued certificate on the CTERA Portal is required to upload the root CA to the CTERA Edge Filer so that the edge filer is trusted by the CTERA Portal. The certificate covers the following:

  • The connection between the edge filer and the portal.
  • When the object storage used by the CTERA Portal is accessed by Direct Mode and uses a X.509 Certificate signed by a private Certification Authority (a self-signed certificate) and not a public trusted certificate.
  • The connection between the edge filer and a Syslog server.

The edge filer includes a self-signed certificate. Details of this certificate are displayed by accessing System > Certificates in the navigation pane.
