SNMPv1 and SNMPv2c do not provide security, authentication, or encryption.
Without authentication, an unauthorized user could perform SNMP network
management functions and eavesdrop on management information as it passes
from system to system. Many SNMPv1 and SNMPv2c implementations are
restricted read-only access, which, in turn, reduces the effectiveness of a network
monitor in which network control applications cannot be supported.
To implement SNMPv3, an authentication and encryption method must be assigned
to a user in order to be validated by the 7705 SAR. SNMP authentication allows the
router to validate the managing node that issued the SNMP message and determine
if the message was tampered with.
