SNMPv3 Security Features
SNMPv3 provides secure access to devices by a combination of authenticating and encrypting frames over
the network. SNMPv3 authorizes management operations only by configured users and encrypts SNMP
messages. The SNMPv3 User-Based Security Model (USM) refers to SNMP message-level security and offers
the following services:
• Message integrity—Ensures that messages have not been altered or destroyed in an unauthorized manner
and that data sequences have not been altered to an extent greater than can occur non-maliciously.
• Message origin authentication—Ensures that the claimed identity of the user on whose behalf received
data was originated is confirmed.
• Message confidentiality and encryption—Ensures that information is not made available or disclosed
to unauthorized individuals, entities, or processes.
