Secure Sockets Layer (SSL) Server Certificates

CMC includes a Web server that is configured to use the industry-standard SSL security protocol to transfer encrypted data 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. CMC employs the 128-bit SSL encryption standard, the most secure form of encryption generally available for Internet browsers in North America.

The CMC 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 CMC to generate a new Certificate Signing Request (CSR).

At boot time, a new self-signed certificate is generated if:
  • A custom certificate is not present
  • A self-signed certificate is not present
  • The self-signed certificate is corrupt
  • The self-signed certificate is expired (within 30 day window)
The self-signed certificate displays the common name as <cmcname.domain-name> where cmcname is the CMC host name and domain-name is the domain name. If domain name is not available it displays only the Partially Qualified Domain Name (PQDN), which is the CMC host name.
