The 2011 presentation analyzes the March 4 DDoS activity and response, with packet observations showing HTTP GET requests to the root path, Cache-Control values such as no-store and must-revalidate, Proxy-Connection Keep-Alive, rotating Accept and User-Agent headers, and request intervals averaging about four seconds. It broadens the response guidance to Layer 7 and application-level denial-of-service techniques, including Slowloris, RUDY, random-parameter GET flooding, torrent redirection, XML billion-laughs payloads, zip bombs, and PCRE backtracking abuse. The material also discusses emerging mobile, IPTV multicast, and IPv6 denial-of-service scenarios and recommends controls such as endpoint/server validation, network authentication or isolation, router-advertisement detection, and performance-aware signatures.
