HAPTER 7: SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
SNMP Security
SNMP controls access according to three security models: SNMPv1,
SNMPv2c, and SNMPv3.
A security level is the permitted level of security within a security model.
SNMPv1, SNMPv2c, and SNMPv3 differ in the level of security they provide.
SNMPv1 and SNMPv2c perform no authentication that, for example,
safeguards against spoofing. For these models, Cuda 12000 supports no
authentication, but supports authentication of identity and privacy through
encryption for SNMPv3.
The bases for access control for each of the security versions is shown in ().
