The Oracle Communications Session Border Controller supports SNMPv3 by default. To secure your SNMPv3 system, you must configure SNMP users and groups, SNMP managers, and view access to MIB trees. SNMPv3 provides the SNMP agent and SNMP Network Management System (NMS) with protocol security enhancements used to protect your system against a variety of attacks, such as increased authentication, privacy, MIB object access control and trap filtering capabilities.
