5. Page 5 - Company Confidential Distributed Denial of Service (DDoS)

6. Page 6 - Company Confidential During a Distributed Denial of Service (DDoS) attack, compromised hosts (bots) or vigilante users from distributed sources overwhelm the target with illegitimate traffic so that the servers can not respond to legitimate clients. What is a DDoS Attack? 6

7. Page 7 - Company Confidential The DDoS Attack Surface  Any part of your network or services that is vulnerable to an attack – Network Interfaces – Infrastructure – Firewall/IPS – Servers – Protocols – Applications – Databases  Attackers will find the weakness

8. Page 8 - Company Confidential DDoS Threats are Top of Mind  4 of the top 6 threats seen over the last 12 months are DDoS related  The top 4 perceived threats for the next 12 months are DDoS related  DDoS threat awareness is high Source: Arbor Networks 2011 Infrastructure Security Report

9. Page 9 - Company Confidential Sources of Data  2011 Worldwide Infrastructure Security Report – Survey of Internet operators focused on security practices, incidents and trends – 114 respondents worldwide – Data based on measurements, insights and opinions of respondents  ATLAS Data Trends – Data collected from 100+ Arbor deployments and honeynets sharing attack and traffic statistics – Empirical data based on measurements taken in production deployments

10. Page 10 - Company Confidential 2011 Infrastructure Security Survey  Survey conducted in October through November 2011  114 total respondents across different market segments  54% service providers, 15% T1 providers  “Other” includes VOIP, wholesale internet, DDoS mitigation, database repository payment and credit sites

11. Page 11 - Company Confidential Key Findings in the Survey  Ideologically-motivated ‘Hacktivism’ and On-line vandalism DDoS attacks are the most commonly identified attack motivations  10 Gbps and Large Flood-Based DDoS Attacks Are The “New Normal”  First-Ever Reports of IPv6 DDoS Attacks 'in the Wild' on Production Networks  Increased Sophistication and Complexity of Application Layer (Layer 7) DDoS Attacks and Multivector DDoS Attacks Are Becoming More Common  Continued Uncertainty Around Visibility & Security of Mobile/Fixed Wireless Networks  Stateful Firewalls, IPS and Load-Balancers Devices continue to Fall Short on DDoS

12. Page 12 - Company Confidential DDoS Attack Frequency over last 12 Months  91% of respondents see at least 1 DDoS attack per month up from 76% in 2010  44% of respondents see 10 or more attacks per month up from 35% in 2010

13. Page 13 - Company Confidential Top DDoS Motivations  Top two attack motivation categories are fueled by personal beliefs and inclinations of attackers  Exponential increase in risk of being attacked

14. Page 14 - Company Confidential Large Attacks are Now Commonplace  Aggregate attack sizes have leveled off but remain at levels capable of overwhelming most Internet operators  13% of respondents report attacks above 10 Gbps  40% of respondents report attacks above 1 Gbps  Largest pps attack reported is 35 Mpps keeping pace with 2010

15. Page 15 - Company Confidential Max BPS Misuse DDoS attacks per country in LAT 2011  Largest bps attack in LAT 10.465 Gbps in Brazil  Largest bps attack reported is 60 Gbps WW

16. Page 16 - Company Confidential Avg BPS Misuse DDoS attacks per country in LAT 2011  Top Avg BPS attacks above 1 Gbps in LAT, Perú and Uruguay.  40% of respondents report WW attacks above 1 Gbps

17. Page 17 - Company Confidential Max PPS Misuse DDoS attacks per country in LAT 2011  Largest pps attack in LAT 10.836 Mpps in Brazil  Largest pps attack reported is 35 Mpps WW

18. Page 18 - Company Confidential Avg PPS Misuse DDoS attacks per country in LAT 2011  Top Misuse Avg PPS attacks in LAT 3.064 M pps in Perú

19. Page 19 - Company Confidential Application Layer and Multi-vector DDoS  A higher percentage of attacks reported on HTTP and IRC relative to 2010 – HTTP (87% vs 84%) and on IRC (11% vs 0%) relative to 2010  Lower percent of attacks on DNS, SMTP, HTTPS and VOIP – DNS (67% vs 76%), SMTP (25% vs 40%), HTTPS (24% vs 35%) and VOIP (19% vs 38%)  SSL based attacks reported included TCP and UDP floods against port 443, port scanning attempts and Slowloris

20. Page 20 - Company Confidential Destination ports breakout DDoS attacks in LAT 2011 9%  53 7%  80 4%  IP fragment (0)

21. Page 21 - Company Confidential Most Common Application Layer Attacks Seen  Majority of known attack types are focused against web properties

22. Page 22 - Company Confidential DDoS Attacks Against Data Centers  56% of Data Center respondents observed DDoS attacks in 2011  The percentage is down from 2010 which showed 69%  25% of respondents observed DDoS attacks that exceeded the total bandwidth into the Data Center  2010 which was only 15%

23. Page 23 - Company Confidential Fragility of Stateful Devices in the IDC  Over 40% of respondents reported an inline firewall and/or IPS failing due to a DDoS attack.  This is slightly lower number than 2010 where 49% reported a firewall and/or IPS failure.  10% of respondents do not put firewalls/IPS in front of IDCs  96% of respondents use load balancers within their IDCs  43% of respondents reported a stateful Load Balancer (or ADC) going down due to a DDoS attack

24. Page 24 - Company Confidential DDoS Event Response Drills  Almost 70% of survey respondents have never practiced responding to a DDoS Attack event  Only 2% improvement in percentage of respondents that have rehearsed attack responses

25. Page 25 - Company Confidential CERTs  Not my job  None in my region  We don’t see a need  Organization not big enough  Input from such bodies not deemed useful  Does your organization have a CERT or CSIRT (e.g., KPRCERT)?  66% of respondents collaborate with a Government or National CERT/CSIRT  Those that don’t cite several reasons why. Most due to lack of time or CERT

26. Page 26 - Company Confidential Mobile Services are Pushing Technology Adoption  27% of survey respondents offered mobile services  Ranging from 1M to over 100M subs  Range of subs shifted up, reflecting growth in Mobile  LTE availability accelerating  LTE offered by 28.6%, up from 9% last year  Another 52% plan to have LTE deployed by 2014  IPv6 goes ahead  50% plan to introduce IPv6 within next 12 months.  9.6% already have it.

27. Page 27 - Company Confidential Mobile Infrastructure DDoS Attacks  50% see application layer attacks on their networks  Broad spread of attack types - similar to what we see elsewhere  DNS is the most common target – target with the most widespread damage potential  Surprise that HTTP was not top as last year, especially given general trends

28. Page 28 - Company Confidential IPv6 Rollout and Growth  Two thirds of respondents have deployed IPv6 in their networks  Majority of those who deployed IPv6 are using IPv6 for internal addressing of their network infrastructure  Two thirds of those who have not deployed IPv6 plan to do so in near term  Traffic and volume remain low with varied forecasts for growth  One respondent provided following answer indicating overall mood: – “depends of what youtube and company are doing ;)”

29. Page 29 - Company Confidential IPv6 DDoS Attacks  First report of an IPv6 DDoS attack in the history of the WISR  Low frequency of attacks reflect low adoption of IPv6 for critical services

30. Page 30 - Company Confidential DNS Security is a Focus  Numbers are consistent with 2011 survey.  87% of all respondents offer DNS services.  77% have security teams responsible for DNS Services – 63% Main Security Group – 23% No Security Group – 14% Specific Security Group

31. Page 31 - Company Confidential Outages from DNS Attacks  Overall attack frequency has increased year over year  DNS attacks are down a little – 67% in 2011 vs 76% in 2010  Outages from DNS attacks are much lower – 13% in 2011 vs 32% in 2010  Conclusion: DNS attack defense is improving
