Hi Amplification attacks and syn floods are just touching the surface of ddos attack vectors. You should look into some industry reports: Here are a couple examples to get you started. https://www.radware.com/ert-report-2015/ http://www.verizonenterprise.com/verizon-insights-lab/dbir/2016/ Sent via the Samsung GALAXY S® 5, an AT&T 4G LTE smartphone -------- Original message -------- From: Martin Bacher <ti14m028(a)technikum-wien.at> Date: 4/29/2016 2:02 AM (GMT-08:00) To: Tyler Haske <tyler.haske(a)gmail.com> Cc: NANOG list <nanog(a)nanog.org> Subject: Re: BGP FlowSpec Hello Tyler, thanks for your reply. > Am 28.04.2016 um 17:37 schrieb Tyler Haske <tyler.haske(a)gmail.com>: > > Martin, > > > > Last but not least: I am also looking for anonymized statistical data about DDoS attacks which I could use in the thesis.

I just had a look on that and thought that its only be able to detect some of the attacks. You might not detect large state of the art reflection and amplification attacks with that method. But i think it is useful for some sort of attacks like SYN flood.

Sure, I will definitely think about hat. Thanks again for your reply and for providing the links. Greetings, Martin > > Regards, > > Tyler >
