We will discuss everything from proper configuration, to implementing security policies, to recommendations for system maintenance.

Whether you are new to IT security or a seasoned professional, the following tips will be a valuable resource to ensure your security practices are aligned with industry best practices.

Managing Resources Efficiently

Disable all unnecessary management features. If SSH or SNMP are not necessary for you, it is best to disable them to avoid possible infiltrators.

Put the most used firewall rules at the top of the interface list and log only the necessary traffic. Recording logs can slow performance, especially if it is on an internal hard drive. Fortunately, Fortinet offers alternatives in the cloud or with appliances.

Enabling Only Necessary Inspections

In your Fortigate Firewall, enable only the necessary application inspections. Keep alert systems to a minimum. If you send logs to a syslog server, you probably don't need SNMP or email alerts, which will avoid redundant processing.

Establish scheduled FortiGuard updates at a reasonable frequency to keep your network security always up to date.
