Answer 1

1. Simple Network Management Protocol version 1(SNMPv1), (SNMPv2) is a managing devices used to monitor devices in a computer network while the Simple Network Management Protocol version 3 (SNMPv3) is the latest version of the SNMP.
2. SNMPv1,SNMPv2 has a complex party-based security system while the SNMPv3 has a cryptographic security system.
3. SNMPv2 agents can be used as proxy agents for SNMPv1 managed devices.
4. SNMPv2 introduced the Inform features which allow acknowledgement of the receipt of messages by the manager while the SNMPv3 introduced an enhanced security system that authenticates messages and ensures their privacy especially if they are forwarded through the Internet.
5. The protocol for SNMPv1, STD 15 describes a basic approach to security and administration. The SNMPv3 framework provides protection against common threats to network management operations, namely Modification of Information, Masquerade, Disclosure, and Message Stream Modification. SNMPv3 protects against these threats by providing the security services of Data Integrity, Authentication, Privacy (Confidentiality), and Message Timeliness.

In addition SNMPv3 provides Access Control, which ensures that requesting managers are authorized to retrieve or modify management information.
