What layer of FortiOS architecture does an application process or daemon run on?

An application process or daemon in FortiOS runs in the user space. The user space is where application-level processes execute, allowing these processes to interact with the kernel while operating in a protected memory area. This separation ensures that user-level applications do not interfere directly with the core functions of the operating system, which reside in the kernel space.

In FortiOS, the user space handles applications such as daemons responsible for various functions like logging, network processing, and management tasks. By isolating these functions from the kernel, FortiOS maintains system stability and security while allowing for more flexible application development and deployment.

The kernel space, in contrast, is reserved for the core components of the operating system, and while it manages system resources and hardware communication, it does not run application-level processes directly. Management space and virtual space are not standard terminology used in the context of FortiOS architecture. This further emphasizes the significance of user space as it pertains to running application processes and daemons.
