What's On Your Network?
An anonymous reader writes "According to a Whitedust article you may currently have more on your network than you think you do. The article claims that not much security attention is generally given to one of the most elusive aspects of computer security; that of physical connectivity." From the article: "Broadcast traffic is on the rise, with more suspicious user activity in the logs every day. Then one morning you get a call from your irate boss wanting to know why he no longer has a network connection, yet the employees - or students or whoever - down the hall are able to play games and visit porn sites, at blazing speeds no less."
if you don't run DHCP, a fun project is to throw a DHCP server out there and see who gets configured.
It's amazing all the little devices that show up. Switches, old print servers, workstations tucked away in a corner somewhere that time forgot....now that many of these networks are starting to push 10 years, it's like archeology.
Every now and then you find something that you just can't physically find. Lotsa fun.
Apparently, kids drive around with laptops looking for open network closets. These fuckers plugged in a cat5e into my switch and started leeching bandwidth for all their friends. I've recommended that my neighbors start locking their doors and change keys often just in case. Also, if you notice any unexplained cat5 going out doors into the back yard, you should investigate.
You see, it is like a network security guild. If you don't know everything about network security then you shouldn't be allowed to learn anything more about network security.
Clearly this is a very effective way to improve the security on the networks around the world... ah, pardon the pun, I mean the Job Security for our dear paid up members of the Network Security Guild.

..the BOFH excuse server. The random answer it gave me was singularly appropriate although unhelpfully honest:
your excuse: because of network lag due to too many people playing deathmatch
