What is a prerequisite for a FortiSIEM supervisor with a worker deployment using the proprietary flat file database?

In a FortiSIEM deployment, particularly when utilizing a worker deployment with a proprietary flat file database, one key requirement is that the event database must be hosted on a Network File System (NFS). This scenario ensures that the supervisor and worker nodes can access and share the event data efficiently across the network.

The use of NFS for the event database allows for centralized management of the log data, which is critical for maintaining the integrity and accessibility of the event information needed for effective security monitoring and analysis. NFS provides scalability, enabling the environment to handle a growing volume of event data as the organization's needs evolve.

Additionally, employing NFS ensures that all workers can read from and write to the event database without direct dependencies on local storage solutions, which can be limiting and less efficient in a distributed processing model like that employed by FortiSIEM. Thus, having the event database on NFS is essential for optimal functionality in such deployments.
