Overview
Authentication
Authentication verifies the identity of a user or a network device (such as an
APC Switched Rack PDU). Passwords typically identify computer users.
However, for transactions or communications requiring more stringent
security methods on the Internet, the Switched Rack PDU supports more
secure methods of authentication.
• Secure Sockets Layer (SSL), used for secure Web access, uses digital
certificates for authentication. A digital CA root certificate is issued by a
Certificate Authority (CA) as part of a public key infrastructure, and its
digital signature must match the digital signature on a server certificate
on the Rack PDU.
• Secure SHell (SSH), used for remote terminal access to the Rack
PDU’s control console, uses a public host key for authentication rather
than a digital certificate.
How certificates are used. Most Web browsers, including all browsers
supported by the Switched Rack PDU, contain a set of CA root certificates
from all of the commercial Certificate Authorities.
