If you have a linux machine handy or some other unix-like OS around, you can do a quick and dirty cron job using nmap:
nmap -sP 192.168.1.0/24 |grep "^Nmap scan report for" >devices1 && diff devices0 devices1 |grep "^>" && rm devices0 && mv devices1 devices0

Open in new window


cron can automatically email you when a command produces output, so in this case you would get a list of all new devices on the network that respond to an ICMP ping.

There probably is better software to do this, but this should work in a pinch

depending the size of the network and how tightly you want to control it, you could simply restrict access by MAC address authentication on the network switches.

Understanding Web Applications

Without even knowing it, most of us are using web applications on a daily basis. Gmail and Yahoo email, Twitter, Facebook, and eBay are used by most of us daily—and they are web applications. We often confuse these web applications tools for websites.  So, what is the difference?

You can do that with a script like BasementCat recommended or with monitoring software....The issue you are going to have is that unless your environment is extremely static (no laptops and people don't turn off their PCs) you will get so many alerts that your will won't have the time to investigate each and determine if it is a rogue machine, or just some restarting their device.

You can build as much logic into the script as you needed and reach your goal, but I just think you would be better off to buy some managed switches and be done.  (if security is truly that important then the customer will spend the money)

It's always a balancing act when it comes to asking people to spend money, but I look at it like this.  If it going to cost me more money (because of my time) than it's going to save the company then it's time to spend the money.
