What is difference between SNMP v2 and v3?

Main difference between SNMP v2 and SNMP v3 are the enhancements to the security and remote configuration model. SNMP v3 adds cryptographic security to SNMP v2. SNMP v3 replaces the simple password sharing (as clear text) in SNMP v2 with a much more secure encoded security parameters.

Which is used for encryption of SNMPv3 data?

SNMP v3 uses MD5, Secure Hash Algorithm (SHA) and keyed algorithms to offer protection against unauthorized data modification and spoofing attacks. If a higher level of security is needed the Data Encryption Standard (DES) can be optionally used in the cipher block chaining mode.

Does SNMPv3 use community strings?

For SNMPV3 there are NO community strings.

Does SNMPv3 use TLS?

Which three security services are provided with SNMPv3?

Security and Administration

SNMPv3 protects against these threats by providing the security services of Data Integrity, Authentication, Privacy (Confidentiality), and Message Timeliness.

What is SNMP v3 privacy?

Privacy allows for encryption of SNMP v3 messages to ensure confidentiality of data. The privacy protocols provide a higher level of security than is available in SNMP v1 and v2c, which use community strings for security. Both authentication and privacy are optional.
