Backup Exec generates a self-signed SSL certificate for the first time hostname configuration, which is by design and is not an issue.
"SSL Certificate Cannot Be Trusted" and "SSL Self-Signed Certificate" reported vulnerabilities can be safely ignored.
"SSL Certificate with Wrong Hostname" reported vulnerability can be safely ignored. The Backup Exec OpenSSL framework that generates certificates, considers NetBIOS name instead of FQDN which causes the mismatch.
