Does SNMP version 1 and 2 Support TLS?

I'm trying to send a message via SNMP version 1 or 2. I need TLS support for safe transmission.

Does both version support TLS? (I'm using SNMP4j Library in Java)

Solution

  • No, SNMP v1 and v2 send everything in plaintext over the network.
    You have to use SNMP v3 together with the security level authPriv.

    Note: SNMP v3 also support the security levels noAuthNoPriv and authNoPriv which will send the data unencrypted, too.
