WHY IT NEEDS A POLICY

Why set_daita needs a policy

This tool creates or modifies VPN configuration settings (DAITA feature toggle), which is a reversible Write operation. It does not execute arbitrary code, delete data permanently, or involve financial transactions. The severity is medium because misconfiguration of VPN security features could expose traffic analysis vulnerabilities, but the change is easily reversible.

From the tool's definition Tool name 'set_daita' and description 'Enable or disable DAITA' indicate the tool modifies VPN settings reversibly. DAITA is a toggle setting that can be enabled or disabled without permanent data loss.
