  • The new security modules are added in an nSnmp driver of SNMPv3 to provide the security and administrations. Three levels of security modules are added in SNMPv3 as follows:
    • NoAuthNoPriv
    • AuthNoPriv
    • AuthPriv.
  • The SHA Authentication Protocol is added to support the SNMPv3.
  • The DES, Aes 128, Aes192 , and Aes256 Privacy Protocols are added to support the SNMPv3.
  • The UsmUserTable is added. This table is a part of security.

    • VacmContextTable
    • VacmGroupTable
    • VacmViewTreeTable
    • VacmAccessTable.
  • The AuthPriv exchange of messages is encrypted and decrypted so the MIB walk will take more time.
