Explain the different security measures that each version of SNMP uses. What is the difference between SNMPv1, v2c, and v3?

Discussion About "SNMP" In Network Security

            Simple Network Management Protocol or SNMP is an application layer protocol that monitors and manages network devices connected to LAN and WAN networks. Its function is to provide a network management system that helps networking devices communicate. There are three versions of SNMP: SNMPv1, SNMPv2 and SNMPv3. SNMPv1 is the original version, while SNMPv2 and SNMPv3were created later as an advancement of the first. SNMPv1builds trust between the managers and the agents’ using communities (Networks, 2021). SNMPv1 has broadly adopted bees; it offers the basic functionality of data polling without using many resources since it does not require an encryption algorithm. SNMPv2 advanced the significance of the protocol. It transmits essential data in the form of clear text, so it does not entirely provide the security concerns of SNMPv1. SNMPv3 went through a significant redesign with security as a priority. It offers services such as authentication of the user account User and non-compulsory encryption of data packages, which are key elements that enhance data security.

SNMPv1is the first model of SNMP. Notably, this form consummated its open objectives as well as a standard protocol but deployed in some applications. It seemed to be deficient in some areas. Smaller RTUs also support it. SNMPv2c was another form of V1 but a little advanced. The main difference that distinguishes it from V1 is the uniform command (Scarpati,2021).  SNMPv3, which is the latest form, is a critical feature that contrasts it from the rest is that its security levels are more boosted. The entities in SNMPv3 are uniquely identified n the EngineID that authenticates messages in the network.
