Botnets Using Ubiquity For Security 95

Posted by kdawson
from the whack-a-c-and-c dept.
Trailrunner7 sends in this excerpt from Threatpost: "As major botnet operators have moved from top-down C&C infrastructures, like those employed throughout the 1990s and most of the last decade, to more flexible peer-to-peer designs, they also have found it much easier to keep their networks up and running once they're discovered. When an attacker at just one, or at most two, C&C servers was doling out commands to compromised machines, evading detection and keeping the command server online were vitally important. But that's all changed now. With many botnet operators maintaining dozens or sometimes hundreds of C&C servers around the world at any one time, the effect of taking a handful of them offline is negligible, experts say, making takedown operations increasingly complicated and time-consuming. It's security through ubiquity. Security researchers say this change, which has been occurring gradually in the last couple of years, has made life much more difficult for them. ... Researchers in recent months have identified and cleaned hundreds of domains being used by the Gumblar botnet, but that's had little effect on the botnet's overall operation."

I agree with you to a certain point. I did my undergrad at a brick and mortar school and loved it and can't imagine wanting to miss out on the whole "college experience". However, a couple of years ago I decided to add some resume fodder, and started my online Masters in Computer Science thru Colorado State University. We watch/listen to the same lectures that they do on campus and do the same assignments. So the course work is the same, but you do miss out on getting to know your professors which is a negative (but only a small one). However, I have made some pretty good friends while doing the online program while working on group projects, so the student networking is still there to a certain degree.

Since the wi-fi would cover the restaurant and other public areas, they don't want folks surfing porn where other customers could see it. And as a side benefit, I would also like to be able to block P2P traffic that would use excessive bandwidth. Does anybody have an suggestions for a setup to handle this sort of thing? I would obviously like to use linux and other free software if possible."
