Visualware Rolls Out a Sanity Saver
eLABorations: Low-cost internal TCP port monitor helps keep unsophisticated crackers at bayUsing a variety of tools to track network security is a good way to stay sane on the job. Of particular value are products that help monitor network probes inside your protected network. I just looked at Visualware Inc.s VisualLookout 2.0, a TCP port monitoring and alerting tool, and found that it can indeed be a sanity saver for network managers. I installed VisualLookout on my lab machines and got a good picture of the incoming and outgoing traffic patterns, with almost no effort and very little expense. The product costs just $39.95 to monitor up to 100 systems running a variety of OSes. This is a good tool to use inside the firewall to monitor for internal network probes. I was easily able to set up alerts that told me when ports were being probed.
VisualLookout 2.0 can also monitor external traffic and uses a world map to locate traffics likely origin. Although skillful crackers can circumvent this technique with no problem, it is a handy tool to have just in case one of them gets sloppy. And it will bust the newbie attackers without much effort at all.
