WHAT IT DOES

What update_firewall_address does on Fortimanager

AI agents use update_firewall_address to create or update resources in Fortimanager, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Fortimanager environment.

RISK

Why update_firewall_address is rated Medium

This tool modifies firewall address objects, which is a reversible Write operation. It does not delete data (Destructive), execute arbitrary code (Execute), nor involve financial transactions (Financial). The blast radius is high because misconfigured firewall addresses could disrupt network traffic or create security gaps, but the operation itself is reversible if corrected.

From the tool's definition Tool name 'update_firewall_address' indicates modification of firewall address configurations. Sibling tools like 'add_device_to_group', 'add_interface_to_zone', 'add_ips_rule' confirm this server performs network/security configuration changes.
