About security management and certificates in NetBackup
NetBackup uses security certificates to authenticate the NetBackup hosts. The security certificates conform to the X.509 Public Key Infrastructure (PKI) standard. A master server acts as the Certificate Authority (CA) and issues digital certificates to hosts. NetBackup uses Transport Layer Security (TLS) protocol for host communication where each host needs to present its security certificate and validate the peer host's certificate against the Certificate Authority (CA) certificate.
The NetBackup 8.1 and later hosts can communicate with each other only in a secure mode. These hosts must have a Certificate Authority (CA) certificate and a host ID-based certificate for successful communication.
Any security certificates that NetBackup generated for 8.0 and earlier hosts are referred to as host name-based certificates. For more details on these certificates, refer to the NetBackup Security and Encryption Guide.
