User names, passwords, community names (SNMP)
All user names, passwords, and community names for SNMP are
transferred over the network as plain text. A user who is capable of
monitoring the network traffic can determine the user names and
passwords required to log on to the accounts of the control console or Web
interface of the Battery Management System. If your network requires the
higher security of the encryption-based options available for the control
console and Web interface, be sure to disable SNMP access or set its
access to read-only. (Read-only access allows you to receive status
information and to use SNMP traps.)
