WHY IT NEEDS A POLICY

Why set_zone_template needs a policy

The name 'set_zone_template' implies assigning or applying a configuration template to a network zone, which is a write operation (modifying zone configuration). This is potentially high severity because misconfiguring a DDoS mitigation zone template could leave infrastructure unprotected or disrupt active mitigations. Confidence is reduced due to empty description.

From the tool's definition Tool name 'set_zone_template' and sibling tools like 'import_zone_template', 'get_zone_template', 'list_zone_templates' suggest this tool applies or assigns a template to a zone on a DDoS mitigation device.
