Managing Resources Efficiently
Disable all unnecessary management features. If SSH or SNMP are not necessary for you, it's best to disable them to avoid possible infiltrators.
Put the most commonly used firewall rules at the top of the list of interfaces and only log the traffic you need. Recording logs can slow down performance, especially if it's on an internal hard disk. Fortunately, Fortinet offers alternatives in the cloud or with appliances.
Activating Only Necessary Inspections
In your Fortigate Firewall, activate only the necessary application inspections. Keep alert systems to a minimum. If you send logs to a syslog server, you probably won't need SNMP or e-mail alerts, which will avoid redundant processing.
Establish scheduled FortiGuard updates with reasonable frequency to keep your network security up to date.
