Which Network Monitoring Protocol Provides Authentication and Encryption?
A network administrator is planning to implement device monitoring to enhance network visibility. The security team requires that the solution provides authentication and encryption. Which of the following meets these requirements?
Community Votes
100% of anonymous learners picked answer D. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
This question tests your knowledge of network management protocols and their security features; the common trap is confusing standard Syslog or NetFlow with a protocol capable of encryption and authentication.
For secure device monitoring with authentication and encryption, SNMPv3 is the correct choice. Community consensus confirms SNMPv3 as the protocol that meets these security requirements in the CompTIA Network+ N10-009 context.
Choosing Syslog: Syslog is a common monitoring tool but traditionally lacks strong authentication and encryption, whereas SNMPv3 is designed specifically for secure management.

Expert Analysis
Why the Answer Is Correct
SNMPv3 (Simple Network Management Protocol version 3) is the only option that provides both authentication and encryption for device monitoring. It supports user-based security with authentication and privacy (encryption) features, making it suitable for secure network visibility.
The question asks for a monitoring solution that provides authentication and encryption, and SNMPv3 supplies both through its security model. Community comments unanimously point to SNMPv3, with likes confirming the answer.
Why the Other Options Are Wrong
SIEM (Security Information and Event Management) is a system for collecting and analyzing security logs, not a network device monitoring protocol. While it may use secure channels, it doesn't inherently provide authentication and encryption for monitoring itself.
Syslog is widely used for logging and device monitoring, but standard Syslog sends messages in clear text and does not include built-in authentication or encryption. NetFlow is a flow-based monitoring protocol that exports packet statistics, but it lacks the robust security features required by the security team.
Community Comment Notes
Community members provided short, direct responses all selecting D, reinforcing that SNMPv3 is the accepted correct option. One comment specifically states "SNMPv3 provides authentication and encryption," which directly matches the requirement in the question.

Exam Strategy
When you see a question asking for a monitoring technology that includes authentication and encryption, immediately eliminate generic protocols like Syslog and NetFlow. Remember that SNMPv3 is the secure version of SNMP and is the only management protocol specifically offering both authentication and privacy.
