|Note: the External Path Analysis is available starting with NP-View version 4.2.0|
Through network access modeling, NP-View analyzes all possible connectivity paths in a network based on the firewall, router, and switch configuration files imported. The results are presented in:
- the Connectivity Paths table,
- the Compare Path History,
- the Connectivity Matrix for each device, and
- the Inbound Connectivity and Outbound Connectivity sections of the info panel for hosts, gateways, and networks.
Path analysis is only available in custom views that have been manually created using the “Manage Views” menu. The default Home view in which only devices are shown (no network, no end points) does not include a path analysis.
NP-View provides two options for analysis; Standard and External. Standard analysis computes paths for all the devices and end points within the view. External analysis include not only devices and end points within the view but also external end points that are listed as unmapped.
By default, new view created include the standard analysis. To include external hosts, select the checkbox “Include external (unmapped) hosts in path analysis” at the bottom of the Create New View form. Please note that the external path analysis will likely take more time to complete and will return a larger number of paths.
