3 Infoblox Inc. All Rights Reserved. Preface
4 The Problem DNS-based attacks are on the rise Traditional protection is ineffective against evolving threats DNS outage causes network downtime, loss of revenue, and negative brand impact Unprotected DNS infrastructure introduces security risks Infoblox Inc. All Rights Reserved.
5 Why is DNS an Ideal Attack Target? DNS is the cornerstone of the Internet, used by every business and government DNS protocol is stateless and hence vulnerable DNS as a protocol is easy to exploit Maximum impact with minimum effort Infoblox Inc. All Rights Reserved.
6 Advanced DNS Protection - DDOS Infoblox Inc. All Rights Reserved.
7 2013 DNS Threat is Significant Attacks against DNS infrastructure growing DNS-specific attacks up 200% in 2012 ICMP, SYN, UDP attacks growing significantly too DNS is #2 attack vector protocol HTTP 87% DNS 67% SMTP 25% HTTPS 24% SIP/VOIP 19% IRC 11% Other 7% 0% 20% 40% 60% 80% 100% Source: Arbor Networks Infrastructure Layer: 76.52% ACK: 1.69% CHARGEN: 3.37% FIN PUSH: 0.39% DNS: 8.94% ICMP: 11.41% RESET: 1.94% RIP: 0.13% RP: 0.39% SYN: 18.16% SYN PUSH: 0.13% TCP FRAGMENT: 0.65% UDP FLOODS: 14.66% UDP FRAGMENT: 14.66% Source: Prolexic Quarterly Global DDoS Attack Report Q Infoblox Inc.
