• To enable a security service, check the box in the Enable column. By default,
only the Network Reputation service is enabled.
NOTE If you enable the IM & P2P Blocking service, it will enable both the IPS
service and the IM & P2P Blocking settings. If you enable the IPS
(Signature) service, it will enable both the IPS service and the IPS
Policy and Protocol Inspection settings. Disabling the IM & P2P
Blocking or IPS (Signature) service will not disable the IPS service.
When both of them are disabled, the IPS service will be disabled.
