Reverse Broadband

I got curious today about the upload/download speed here at the office because I heard that the new Internet Security Routers (ISR) were slowing down traffic at all of the sites.



Too bad I didn't run a speed test before they installed it today. This is interesting, though. I have never seen the upload speed at ten times the download speed.

There is really no way to be accurate here, though. We have around 100-120 machines on the network, and probably several users streaming audio from some website. We also have many computers using a terminal emulator connected to a mainframe in Atlanta, querying data constantly.

But I applaud the I.T. folks for finally going to private addressing. Up until last month, every computer in every office that was connected to the network had a publicly-routable IP address. Very dangerous if you ask me. We're busting at the seams with sensitive data; there is a constant high probability that we could have a very similar incident the VA had earlier this year, or a network break-in like NASA had several years ago.

Of course, everyone is subject to the vulnerabilities of social engineering. I encourage everyone to read the interesting (if not also true) stories in Kevin Mitnick's The Art of Deception: Controlling the Human Element of Security. I wonder if our Information Security Manager has read it.
