Fill in the blank: Service blades must be attached to a ______________.

In Check Point's Software Blade Architecture, service blades are software modules that extend security functionality at the enforcement point. They must be enabled on and attached to a Security Gateway because the gateway is the component that actually inspects and enforces traffic - service blades have no operational context without a gateway to run on.

A 'Management container' is not a recognized Check Point architectural component to which service blades can be attached.

A Management Server handles policy management and logging, not traffic enforcement - service blades require an enforcement point, not a management plane component.

'Security Gateway container' is not the correct or standard Check Point term for the component that hosts service blades.
