We used Nessus tool to run security scan on the PA-5020 & PA-3020 series & it identified with the following below medium vulnerability:
The server's X.509 certificate cannot be trusted.
Please let me know, for any fix to this vulnerability.
The management interface on the firewalls doesn't have a trusted certificate, or Nessus does not trust the certificate being used. This could be because you simply haven't installed a certificate for the GUI to utilize which is trusted by your CA, or that Nessus doesn't trust your CA.
