- 1. Multi-vector DDOS Attacks Detection and Mitigation Paul Mazzucco Chief Security Officer January 2016
- 2. Key Reasons for Cyber Attacks Source: Hackmagedden Source: Hackmagedden 4 months later …December 2014
- 3. DoS/DDoS Attacks New Cyber Weapon of Choice Cyber Attack Sophistication Is Increasing • Lower bandwidth attacks occur more frequently, last longer, evade detection - Overwhelm servers, take down site • Multi-vector campaigns - Booter services - Dark DDoS attacks (smokescreens) - Distract victims, other attacks infiltrate corporate networks - DDoS-as-a-Service business model - Botnets for hire, $6/month Cyber Attack Sophistication Is Increasing • Lower bandwidth attacks occur more frequently, last longer, evade detection - Overwhelm servers, take down site • Multi-vector campaigns - Booter services - Dark DDoS attacks (smokescreens) - Distract victims, other attacks infiltrate corporate networks - DDoS-as-a-Service business model - Botnets for hire, $6/month Source: AkamaiSource: AkamaiSource: Imperva
- 4. The Industry Hit List Drivers: the rise of the Internet of Things, web vulnerabilities and botnet building Choice Targets • Competitive industries, e.g. gaming • SaaS platforms, e.g. healthcare data • Multi-tenant platforms: attacks on one tenant impact all other tenants Drivers: the rise of the Internet of Things, web vulnerabilities and botnet building Choice Targets • Competitive industries, e.g. gaming • SaaS platforms, e.g. healthcare data • Multi-tenant platforms: attacks on one tenant impact all other tenants Source: Akamai 20% of DDoS attacks last over 5 days The longest attack in 2015 lasted 64 days
- 5. Lightening Often Strikes More Than Twice 50% of North American and European companies have been attacked • 83% of companies attacked repeatedly • Star Trek Online (STO) – 3 times, Sept ‘15 • Neverwinter Online – 3 times, Sept ‘15 • 54% attacked 6+ times annually • Rutgers Univ – 6 times in 2015 • 25% experienced theft of data or funds • U.S. FTC has reached settlements with 50+ companies over poor data security practices 50% of North American and European companies have been attacked • 83% of companies attacked repeatedly • Star Trek Online (STO) – 3 times, Sept ‘15 • Neverwinter Online – 3 times, Sept ‘15 • 54% attacked 6+ times annually • Rutgers Univ – 6 times in 2015 • 25% experienced theft of data or funds • U.S. FTC has reached settlements with 50+ companies over poor data security practices Source: Akamai Losses greater than 30,000 records Source: Neustar and The Ponemon Institute
- 6. Where Are the Attacks Taking Place? The 7 Layers of the OSI Model Session attacks typically defeat conventional firewalls Source: Akamai Infrastructure-layer DDoS attacks outnumber application-layer attacks 9-to-1 Source: Akamai
- 7. • 88% of application-based attacks came over HTTP • 15% of organizations reported attacks targeting Web application log in pages on a daily basis • UDP fragments becoming the largest portion of network layer attack traffic Source: Akamai • 88% of application-based attacks came over HTTP • 15% of organizations reported attacks targeting Web application log in pages on a daily basis • UDP fragments becoming the largest portion of network layer attack traffic Source: Akamai Significant Attack Vectors Have Emerged
- 8. The Simple Service Discovery Protocol (SSDP) - Top Infrastructure-based Attack Vector SSDP comes pre-enabled on millions of devices – routers, media servers, web cams, smart TVs, printers, automobiles Allows devices to discover each other on a network, establish communication, coordinate activities Attackers are armed with a list of vulnerable devices; use them as reflectors to amplify a DDoS attack SSDP comes pre-enabled on millions of devices – routers, media servers, web cams, smart TVs, printers, automobiles Allows devices to discover each other on a network, establish communication, coordinate activities Attackers are armed with a list of vulnerable devices; use them as reflectors to amplify a DDoS attackSSDP accounted for more than 20% of attack vectors in 2015
- 9. Attackers Quickly Strike Back Attackers are continually developing new attack vectors that defeat mitigation tools They respond in days / hours after mitigation tools are deployed Meaning businesses face two chief challenges: • The increasing complexity of security, i.e. multi-pronged nature of the attacks • Speed at which attackers adapt to new mitigation tools
- 10. Compromise Takes Minutes, Discovery Takes Longer Source: Radware The cost of DDoS attacks • Average $40K per hour • 32% of companies would loose over $100K revenue per hour of attack • 11% of US companies would loose $1 Million+ revenue per hour of attack Source: Neustar 1 in 5 companies were told of attacks by customers, partners, other 3rd parties
- 11. • Envelope Attacks – Device Overload • Directed Attacks - Exploits • Intrusions – Mis-Configurations • Localized Volume Attacks • Low & Slow Attacks • SSL Floods Required Detection: Encrypted/Non-Volumetric Attacks
- 12. • Web Attacks • Application Misuse • Connection Floods • Brute Force • Directory Traversals • Injections • Scraping & API Misuse Required Detection: Application Attacks
- 13. • Network DDoS • SYN Floods • HTTP Floods Required Detection: Volumetric Attacks
- 14. Fight Back – Advice #1 Don’t assume your company is not a target Bake DDoS mitigation into your business resiliency planning Understand that no two DDoS attacks are exactly alike Ensure buy-in from ALL C-suite executives
- 15. Fight Back – Advice #2 Protecting your data is not the same as protecting your business Also review your current investments in system integrity and operational availability Then gauge the increase required to ensure appropriate protection
- 16. Fight Back – Advice #3 You can’t defend against attacks you can’t detect Understand your vulnerabilities in today’s distributed environments
- 17. Fight Back – Advice #4 Evaluate DDoS protection solutions Consider a hybrid approach of layered DDoS defenses: always on, on-premise hardware blocking plus cloud-based traffic scrubbing
- 18. Fight Back – Advice #5 Know your limitations Enlist specialists that have the expertise to help you fight and win
