Hello,
I am curious if there is a solution to map internal networks that do not have connections to internet. We have a large network that is closed off from the outside world, but connected to multiple other networks internally to our organization.
I would like to visualize the inbound connections and at some point also have IN/Out mapped.
Have you seen the Splunk for InterMapper app?
http://splunk-base.splunk.com/apps/51549/splunk-app-for-network-monitoring-and-mapping-beta
It provides the ability to map your network devices (switches, routers, servers etc) on a rack image, world map or even a blank background and then pull it into Splunk. By pulling it into Splunk you can then drilldown on individual devices to see layer 2 and 3 information including any related log data.
What type of network devices are you using to connect to other networks? What kind of bandwidth? Dedicated T1's, what tyope of network devices? Are you using Cisco ( or other brand name technology) I would recommend importing or setting up a syslog reciving port (TCP or UDP) on your Splunk server.
Then analyzing that information.
