Which protocol is used for monitoring Fortinet devices while ensuring secure communication?

The protocol used for monitoring Fortinet devices while ensuring secure communication is SNMP v3. This version of the Simple Network Management Protocol includes enhanced security features that address the vulnerabilities present in earlier versions of SNMP, such as v1 and v2c.

SNMP v3 supports authentication and encryption, providing confidentiality and integrity for the data being sent and received. This is crucial in a network environment where sensitive information may be exchanged and where it is important to prevent unauthorized access or tampering.

In contrast, SNMP v1 and SNMP v2c do not offer adequate security measures, as they transmit data in clear text without encryption or robust authentication mechanisms. While SYSLOG is useful for logging system events, it does not provide the secure communication required for monitoring sensitive network devices. SSH (Secure Shell) is a secure protocol for accessing network devices but is not specifically designed for monitoring purposes like SNMP. Thus, SNMP v3 stands out as the most suitable protocol for secure monitoring of Fortinet devices.
