Furthermore, most organizations that care about security would prefer to also encrypt SNMP protocol in order to have redundant security layers.
If you've got a lot of SNMP v1 & v2c equipment in your network combined with a requirement to use only secure SNMP v3, it may seem like you've been given 2 incompatible goals:
Stop using all of your SNMP v1 & v2c equipment.
Don't spend budget money on new SNMPv3 equipment.
What you need, in order to give your older SNMP gear the advantage of modern security, is a fairly simple box that collects unsecured SNMP messages (traps) before they ever leave the building's local network. The collected traps would then be converted to SNMPv3 before being forwarded to your SNMP manager.
This is becoming the favored solution for military and other government organizations, as well as private companies that need a higher level of security. In today's environment, they most likely won't have the funding to replace all of the installed gear they've deployed in the last decade. Since they can't afford to compromise security, either, they're frequently using SNMPv3 converters instead. A single converter at a site can handle just about any number of local SNMP (v1 or v2c) devices, so purchasing costs are dramatically reduced.
You can also get more than just protocol conversion out of an SNMPv3 converter box. Some are also designed to perform alarm monitoring and management, such as RTUs (discrete inputs, analog inputs, temperature sensors, control relay outputs). If, like most people, you need some general purpose monitoring at any of your locations that have SNMP engines, you can now solve two problems with one device.
The key is to choose a manufacturer that will help you to build an effective system that addresses several of your needs at the same time.
If you're transitioning to SNMPv3 in your network, the NetGuardian 832A G5 can help you make the change. You can start reporting alarms in SNMP v1 or v2c and switch over to v3 whenever you're ready.
SNMPv3 support is a standard feature of the NetGuardian 832A G5 SNMP RTU, allowing you to monitor all of your SNMP devices with enhanced security via message encryption. The NetGuardian allows you to report alarms in SNMP v1, v2c, or v3, leveraging the full NetGuardian feature set and your existing SNMP manager.
