This article explains the different sizes of Internet Service Databases (ISDBs) available to use with FortiOS.
In the new FortiOS version, ISDBs are categorized in three sizes based on hardware and data file size. The 'mini' database size is typically used by default in smaller hardware devices such as FortiGate 50E and 30E.
The following sizes are available:
- Mini: a small-sized ISDB with a very limited amount of available IP addresses.
- Standard: a medium-sized ISDB with most IP addresses available.
- Full: a large-sized ISDB with all IP addresses available (this ISDB is more likely to contain malicious IPs).
The following ISDB services are included in a mini database:
The database type can be verified with the following command:
