2 DDoS Protector 1 (D)DoS Attacks DDoS Protector Behavioral DoS Protection Summary 2

3 What is an DoS Attack? Denial-of-Service attack (DoS attack) an attempt to make a machine or network resource unavailable to its intended users. Distributed Denial-of-service attack (DDoS) is coordinated and simultaneously launched from multiple sources 3

4 (D)DoS Attack Methods and Tools Attacks can be partitioned into three dimensions Network DoS Attack Application flood DoS attacks Directed application DoS attacks Consuming bandwidth resources Target the application resources Exploit application implementation weaknesses 4

5 Attackers Use Multi-Layer DDoS Simultaneous Attack Vectors Large-volume network flood attacks SYN flood attack (e.g., Socket stress) Application vulnerability High and slow application DoS attacks Web attacks: brute force login locked 1 successful attack vector = No service 5

11 Traditional Firewalls Not Sufficient Not Designed for Network and Application DDoS Protection Basic rate based flood protection affects all traffic (Real users and attack traffic) Lacks Comprehensive Layer 7 DDoS protection Poor detection of sly attacks No filters to block attacks and allow real traffic Administrators cannot create custom signatures 11

14 Where to Protect Against DDoS Scenarios: On-Premise Deployment DDoS Protector Appliance + Off-Site Deployment DDoS Protector Appliance 14

15 Integrated Security Management Unified Logs and Monitoring Leverage SmartView Tracker, SmartLog and SmartEvent for historic and realtime security status 15

16 DDoS Protector Logs For attacks with multiple sources / destinations. the DDoS Protector appliance sends several logs to describe the attack With status: start, ongoing, completed And other logs with samples for source / destination (with status: sampled). 16

17 DDoS Protector Integration In SmartView Tracker and SmartLog, each log and log update is being presented separately. In SmartEvent, the attack is consolidated into one event. Therefore SmartEvent In the Event Card, you are able to see the list of all sampled source IPs / destination IPs. 17

18 Real time monitoring with SNMP This realtime monitoring is achived with CactiEZ delivered under GPL. Normal Traffic Currently under attack 18
