Securing DRAC 4 Communications Using SSL and Digital Certificates
The DRAC includes a Web server that is configured to use the
industry-standard SSL security protocol to transfer encrypted date over
the Internet. Built upon public-key and private-key encryption technology,
SSL is a widely accepted technique for providing authenticated and
encrypted communication between clients and servers to prevent
eavesdropping across a network.
SSL allows an SSL-enabled system to perform the following tasks:
• Authenticate itself to an SSL-enabled client
• Allow the client to authenticate itself to the server
• Allow both systems to establish an encrypted connection
This encryption process provides a high level of data protection. The DRAC
employs the 128-bit SSL encryption standard, the most secure form of
encryption generally available for Internet browsers in North America.
The DRAC Web server includes a Dell self-signed SSL digital certificate
(Server ID). To ensure high security over the Internet, replace the Web server
SSL certificate by submitting a request to the DRAC to generate a new
Certificate Signing Request (CSR).
