SNMP is the most popular protocol used for network management. However, lack of security is the major disadvantage of SNMP. Security is essential for SNMP based network management over a public network. The "community string" is the only method of enforcing SNMP security with the current SNMPvl or SNMPv2 protocol. This approach is susceptible to security threats since the non-encrypted community string is easily intercepted and decoded. An attacker can then modify the SNMP agent since there is not any type of authenti- cation provided by SNMP.
