10 Strategies To Fight Anonymous DDoS Attacks

Preventing distributed denial of service attacks may be impossible. But with advance planning, they can be mitigated and stopped. Learn where to begin.

Consider 2011 to be the year that distributed denial-of-service (DDoS) attacks went mainstream.

Who's responsible? Blame Anonymous, according to a new report released Monday by security vendor Radware.

"Their major campaign, Operation Payback, during the WikiLeaks saga in December 2010--against those supporting the U.S. government--was the turning point that shaped the security scene in 2011," according to the report. In short, by distributing easy-to-use DDoS tools, such as low-orbit ion cannon, Anonymous popularized DDoS attacks.

But are DDoS attacks something that businesses and government agencies must simply endure, or, can they be more actively resisted? In fact, organizations can take a number of steps to at least mitigate the effect that DDoS attacks have on their websites, servers, databases, and other essential infrastructure.

1. Know you're vulnerable.
One lesson from the use of DDoS by Anonymous--as well as its sister hacktivist group LulzSec--is that any site is at risk. That's not meant to sound alarmist, but rather simply to acknowledge that the hacktivist agenda can seem random, at best. Indeed, after Anonymous came along, "the financial sector, which had not really considered itself as a prime target, was hit and urgently forced to confront threatening situations," according to the Radware report. "Government sites had been targeted before, but 2011 saw a dramatic increase in frequency, and neutral governments that felt themselves exempt, like New Zealand, were attacked."

2. DDoS attacks are cheap to launch, tough to stop.
As the recent Anonymous retaliation for the Megaupload takedown shows, hacktivists can quickly crowdsource "5,600 DDoS zealots blasting at once," as Anonymous boasted on Twitter, to take down the websites of everyone from the FBI and the Justice Department to the Motion Picture Association of America and Recording Industry Association of America. "DDoS is to the Internet what the billy club is to gang warfare: simple, cheap, unsophisticated, and effective," said Rob Rachwald, director of security strategy of Imperva, via email.

3. Plan ahead.
Stopping DDoS attacks requires preparation. If attacked, "folks that don't take active measures to ensure the resilience of their networks are going to get knocked over," said Roland Dobbins, Asia-Pacific solutions architect for Arbor Networks, via phone. "They need to do everything they can to increase resiliency and availability." Accordingly, he recommends implementing "all of the industry best and current practices for their network infrastructure, as well as applications, critical supporting services, including DNS."

There are other steps that companies and the government can take to stop hackers from breaking into networks, even the Chinese hackers.

re: 10 Strategies To Fight Anonymous DDoS Attacks
IMO most of this is fluff. If the bandwidth of a targetted DOS attack is larger than the pipe it is unstoppable. Really one of the things you mentioned, being friends with your upstream, and your upstreams pipe being bigger than the DOS attacks capacity is the only thing that will help you.

re: 10 Strategies To Fight Anonymous DDoS Attacks
You should also keep a close eye on the security logs for unknown username / password login attempts since they also consume CPU / RAM to manage.. When it comes to Windows servers I personally recommend having a look at Syspeace ( http://www.syspeace.com ) and for Linux fail2ban. Also consider redirecting 404 and 403 errors on webservers to somewhere else, to Google or 127.0.0.1 or something ..

No real information
From what I've seen, the article did absolutely NOTHING on actually providing any worthwhile or relevent information beyond failing horribly at trying to sound helpful.


After reading the comments, this website should fire the author of this article and fill it in with the comments. Going to try a few of them out on myself and see which ones I like best. The commenters were more helpful than this garbage article. I didn't realize we needed to be told how to use common sense.

Re: No real information
I would like to point out that YOU came to THIS article 2 YEARS after it was posted. In the IT field, it's pretty much Rule-of-Thumb that unless it was posted today it most likely isn't relevant. The fault here isn't as much with the author as it is with you. Yes he provided some AMAZINGLY useless information. I mean seriously he named this article "10 Strategies to fight Anonymous DDoS Attacks" and then rode Anonymous's d*** for the entire thing and gave us no actualy strategy to actually fight these attacks. Considering all of that, I still think your comment was stupid and needless since you completely ignored the date it was published.

Let's hope you put more thought into your work than you do your commenting.
