The User-based Security Model (USM) in SNMPv3 provides security services such as authentication and privacy of messages. This security model makes use of a defined set of user identities displayed in the USM user table. The USM user table contains information like:

an authentication protocol, which is an indication that the messages sent on behalf of the user can be authenticated

the privacy protocol
