Overview
Deceive, Snare, and Slow Scan - Sentriant NG appliances use a special "deceiving" technique to
engage and hold TCP-based attacks, thus preventing them from spreading. Snaring stops an
attacking threat from moving to another computer. Slow Scan sends the attacking threat traffic
designed to significantly increase the time it takes for an external host to scan the monitored
network, causing the attacker to consume time and resources.
Track - A Sentriant NG appliance monitors the communication between two or more computers
but does not take a response action.
None - No response is invoked.
The Appliance Health icon represents an aggregate operating status for all Sentriant NG appliances
managed under the SOC. If an error or warning is encountered with an appliance, the icon will change
accordingly displaying the highest severity. For example, a domain made up of four (4) appliances
encounters an error with one appliance and another has a warning. The Appliance Health icon will
show that there is an appliance with an error since it is a higher severity. Clicking on the icon will
navigate to the appliance with the error. The appliance states are described below:
When an appliance is not available, an error message is generated. Clicking on the appliance icon in the
General Status Bar opens the Appliance Availability dialog. The message contains a timestamp of when
the SOC last tried to contact the appliance, and a message that describes the problem. Selecting the
appliance and clicking OK will navigate to the appliance in the Setup > Appliance panel.
The General Status Message displays a textual representation of the filtering done by the Folder List or
Panel Navigation Bar in the Information Panel.
