I want to help

Do you have tips or packet captures (pcap, pcapng, sflow) that you are willing to share? Please open up a github issue / PR and share them.

Interesting opensource projects

https://github.com/pavel-odintsov/fastnetmon ddos detection from sFlow.

https://github.com/jjsantanna/pcap_dns_ddos_analysis packet capture analysis for automation and better understanding a attack

XDP is also a very promising technology for ddos protection:

https://www.mcorbin.fr/pages/xdp-introduction/ introduction article to XDP

https://github.com/xdp-project/xdp-tutorial The holy grail of XDP information. This repository contains a lot of getting-started information for packet handling in the kernel.

https://github.com/PlushBeaver/xdp-syn-cookie syn cookies implemented in XDP space. About 50% faster when runnning in SKB mode than the normal kernel system and toggleable on demand.
