Ensuring DRAC 4 Network Security
The DRAC 4 uses certificate management to ensure security for your DRAC 4 network
communications.
Certificate Management Overview
A Certificate Signing Request (CSR) is a digital request to a Certificate Authority (CA) for a
secure server certificate. Secure server certificates ensure the identity of a remote system and
ensure that information exchanged with the remote system cannot be viewed or changed by
others. To ensure this security for your DRAC 4, it is strongly recommended that you generate a
CSR, submit the CSR to a CA.
After the CA approves the CSR and sends you a certificate, you must upload the certificate to
the DRAC 4 firmware. The CSR information stored on the DRAC 4 firmware must match the
information contained in the certificate.
