Automating network scans
In 2005, the GCN Lab reported on a novel network discovery tool, IPsonar from Lumeta (GCN.com/983).
You might know Lumeta as the company that a few years back published a map of the Internet, which was circulated quite widely.
That was the ultimate application of IPsonar, which ' offered as either an appliance or software ' scans a network with various protocols to see what devices can connect to the outside world and one another. It can work with networks of any size and offers a good way for administrators to find unknown devices and open ports on the network.
Lumeta has just introduced IPsonar 4, which broadens the range of options of what you can do with the results of a scan. For instance, it now includes a score card that offers a color-coded summary of the level of network risk. It can also chart whether network security has gotten better or worse during a selected period of time.
On the other end of the spectrum, Lumeta has also opened the application programming interfaces for IPsonar, which in theory should allow users to connect the scan results with other risk management and network management products.
IPsonar prices start at about $75,000
