If Someone Is Testing Ways To Take Down The Internet, Perhaps It's Time To Build A Stronger Internet
from the let's-get-it-done dept
Recently, some of the major companies that provide the basic infrastructure that makes the Internet work have seen an increase in DDoS attacks against them. Moreover, they have seen a certain profile of attacks. These attacks are significantly larger than the ones they're used to seeing. They last longer. They're more sophisticated. And they look like probing. One week, the attack would start at a particular level of attack and slowly ramp up before stopping. The next week, it would start at that higher point and continue. And so on, along those lines, as if the attacker were looking for the exact point of failure.This article is getting a collective "oh, shit, that's bad" kind of reaction from many online -- and that's about right. But, shouldn't it also be something of a call to action to build a better system? In many ways, it's still incredible that the internet actually works. There are still elements that feel held together by duct tape and handshake agreements. And while it's been surprisingly resilient, that doesn't mean that it needs to remain that way.
The attacks are also configured in such a way as to see what the company's total defenses are. There are many different ways to launch a DDoS attacks. The more attack vectors you employ simultaneously, the more different defenses the defender has to counter with. These companies are seeing more attacks using three or four different vectors. This means that the companies have to use everything they've got to defend themselves. They can't hold anything back. They're forced to demonstrate their defense capabilities for the attacker.
Schneier notes that there's "nothing, really" that can be done about these tests -- and that's true in the short term. But it seems, to me, like it should be setting off alarm bells for people to rethink how the internet is built -- and to make things even more distributed and less subject to attacks on "critical infrastructure." People talk about how the internet was originally supposed to be designed to withstand a nuclear attack and keep working. But, the reality has always been that there are a few choke points. Seems like now would be a good time to start fixing things so that the choke points are no longer so critical.
