The Cisco IOS Block Destination remediation allows you to block traffic sent from the router to the 
destination host in a correlation event.

Do not use this remediation as a response to a correlation rule that is based on a discovery event; 
discovery events only transmit a source host and not a destination host. You can use this remediation in 
response to correlation rules that are based on connection events or intrusion events.
