Comment on Network Scanning Revisited! by Alfred Basta

Alfred Basta — Wed, 21 Jul 2010 15:09:22 +0000

About ten years ago I was working as a Network Administrator managing a medium size network. One of my first tasks in this position was to create a network asset database for all network devices. We already had a high-priced, although functionally deficient, network management tool that just wasn’t making the cut. Using the output from the management tool as a starting point I began painstakingly connecting to each network device, and documenting them to inventory the network. This also involved a lot of hours physically traversing buildings, basements, and wiring closets. Finally, it seemed that I had visited every nook and cranny and identified every router, bridge, switch, hub, and archaic telecommunications device retrofitted to the network. For security, I wrote a UNIX script to connect to the known devices and disable physical ports that weren’t being used and enable security features on the devices. This is when things started to get complicated. Suddenly the help desk phones started ringing and people were complaining of lost network connectivity. Alas, there were even more devices out there that we didn’t know about! Luckily the UNIX script was easily reversible. After hearing my woes that evening a “hacker” friend of mine pointed out a new tool for scanning networks that he read about in Phrack magazine. It was a bit controversial, but it was free and it looked like it could do the job. The next day became my first experience with Nmap, a network scanner, and since that day it has been making my life a whole lot easier.

Regards,

Alfred

My friend and I were recently talking about the ubiquitousness of technology in our daily lives. Reading this post makes me think back to that discussion we had, and just how inseparable from electronics we have all become.

I don’t mean this in a bad way, of course! Ethical concerns aside… I just hope that as technology further develops, the possibility of uploading our brains onto a digital medium becomes a true reality. It’s a fantasy that I daydream about every once in a while.
