What communication protocol is used between an agent and a supervisor in FortiSIEM?

In FortiSIEM, the communication protocol used between an agent and a supervisor is HTTPS. This secure communication protocol ensures that the data exchanged between the agent (which collects and sends log data) and the supervisor (which processes and manages the data) is protected.

HTTPS combines the Hypertext Transfer Protocol (HTTP) with SSL/TLS protocols to provide a secure channel over the internet. This is particularly important in security information and event management (SIEM) systems, where sensitive log data is transmitted. The use of HTTPS helps maintain the confidentiality and integrity of the data, protecting it from interception and tampering.

Using HTTPS also aligns with best practices for network security, emphasizing the importance of secure data transmission in environments where data sensitivity is critical. Other protocols, such as FTP, HTTP, and SSH, do not provide the same level of security for this specific purpose in FortiSIEM, making HTTPS the appropriate choice.
