Authentication
You can choose security features for the Rack PDU that control access by providing
basic authentication through user names, passwords, and IP addresses, without using
encryption. These basic security features are sufficient for most environments in which
sensitive data are not being transferred.
SNMP GETS, SETS, and Traps
For enhanced authentication when you use SNMP to monitor or configure the Rack
PDU, choose SNMPv3. The authentication passphrase used with SNMPv3 user
profiles ensures that a Network Management System (NMS) attempting to
communicate with the Rack PDU is the NMS it claims to be, that the message has not
been changed during transmission, and that the message was not delayed, copied,
and sent again later at an inappropriate time. SNMPv3 is disabled by default.
The Dell implementation of SNMPv3 allows the use of the SHA-1 or MD5 protocol for
authentication.
Web interface and command line interface
To ensure that data and communication between the Rack PDU and the client
interfaces (the command line interface and the Web interface) cannot be intercepted,
you can provide a greater level of security by using one or more of the following
encryption-based methods:
• For the Web interface, use the Secure Sockets Layer (SSL) protocol
• To encrypt user names and passwords for command line interface access, use the
Secure SHell (SSH) protocol
• To encrypt user names, passwords, and data for the secure transfer of files, use the
Secure CoPy (SCP) protocol
