Which of the following is a secure version of the SNMP protocol?

SNMP security improvements come with SNMPv3. The crucial enhancement is the introduction of authentication and encryption through the User-based Security Model (USM), which protects both who is talking to the agent and the content of the messages. It defines security levels such as authPriv (authentication plus encryption), authNoPriv (authentication without encryption), and noAuthNoPriv, giving real options for protecting management data. In contrast, earlier versions rely on community strings sent in plaintext and lack built-in encryption, so they aren’t secure by modern standards. SNMPv3 is the secure choice because it adds these robust security features while the earlier versions do not.
