12.2.3.3 Security Concerns and Measures
Since SNMP allows write-access to configuration parameters, it is important to protect this
interface. The following security measures are available:
„ A community string (password) can be defined for read-only access and for read/write
access.
„ It is possible to limit access to SNMP to a trusted peer (single IP address or a range of
addresses).
„ SNMPv3 provides an significant security improvement over SNMPv1/2. Version 2.8.0
will support SNMPv3 and will allow the service provider to configure SNMPv3 security
parameters.
„ SNMP traffic can be allowed over an IPSec secured connection – check availability
with AudioCodes.
