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:

•the user name

•a security name in the form of a string whose format is independent of the Security Model

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

•the privacy protocol.

The following table describes the SNMPv3 User Table information.
