SNMPv3 Important Points
- Authentication
- MD5 or SHA authentication passphrase hashes
- Passphrase must be greater than 8 characters including spaces
- Privacy
- Packet data may now be DES encrypted (future use allows additional encryptions)
- Passphrase defaults to authentication passphrase
- Allows for unique Privacy passphrase
- SNMPv3 provides for both security models and security levels.
- A security model is an authentication strategy set up for a user and the user’s group
- A security level is the permitted security within the security model
- Three security models are available: SNMPv1, SNMPv2c, and SNMPv3
