When the procedures in this document are applied; You can provide block/unblock operations with firewall in action rules or incident management.
FortiGate firewall product has API support, integration process is provided by API.
As explained in the diagram above, when an alarm with action rules defined for critical security vulnerabilities is triggered, logsign detects it and connects to Fortigate via API protocol. The IP address to be blocked is added as a member to the address group defined in the FortiGate product.
Note: Do not forget that you need to create a rule as Drop or Deny in Address Group in Firewall Policy in order to block.

Address - Read/Write authorization is granted only to access and add members to the address group.

You need to define logsign siem ip addresses to Restrict login to trusted hosts, user access created with this definition will only need to be done with this ip address.
3-> Address Group is created.
The process of adding the IP addresses that we want Logsign to block as a member into the address group is provided. If you want to separate blocking operations based on rules in multiple scenarios, you can create more than one address group in this section.
Example: You can make a separate address group and firewall policy for dos attack alarms, or a destination block address group to prevent access to a malicious domain.
