This tool modifies firewall rules, which are security-critical configuration objects.

From the tool's own definition: "Tool name is 'update_ipv6_firewall_rule' and description states 'Update IPv6 firewall rule'. The verb 'update' indicates modification of existing configuration data (firewall rules) in a reversible manner."
