Technical Tip: ISDB Database updates
| Description | This article describes how the ISDB database gets updated with static and dynamic IPs, and how frequently the updates are released. |
| Scope | FortiGate. |
| Solution | ISDB is a local database service. The automatic engine, part of the ISDB design, collects IPs from multiple sources and updates the database daily, including official documents, ASN Records, DNS lookups, Reverse DNS lookups, SSL Certificates, etc. ISDB uses crawling for automatic source monitoring.
The automatic engine performs the DNS lookup every day and keeps the results for 2 days. Records older than 2 days will not be included in the next release.
Currently, there are two regular releases every day from Monday to Friday, meaning 10 releases every week. The firewall receives two updates per day if configured for automatic updates.
The updates cannot be reflected in real-time as ISDB is not an online service. Any updates can only be reflected along with the package release.
To check which Internet Service database version is in use, use the following command:
diagnose autoupdate versions
Ensure that FFDP upgrades are not disabled under FortiGuard settings:
config system fortiguard get | grep update-ffdb update-ffdb : disable <-------- If 'update-ffdb' is disabled, then enable it using the following command. set update-ffdb enable end
Anyone can report ISDB-related issues directly to the ISDB team via the FortiGuard ISDB contact form or by sending an email to fortiflow@fortinet.com.
