1 Distributed Denial of Service Attacks Dennis Galinsky, Brandon Mikelaitis, Michael Stanley Brandon Williams, Ryan Williams

2 Agenda Types of Attack Source of Attacks Prevention History of Attacks Business Aspect

3 TCP Connection Attack (SYN FLOOD)  Normal Connection  SYN Flood

4  HTTP Get Flood  HTTP Post Flood Application Layer Attack

5 Source of Attack  Botnets What are they? How are they Created? Notable Botnet Army’s ○ Storm ○ Rbot  For-Hire How much does it cost? Rent an Army Threat Level?

6 Prevention  Detect the threat  Mitigate the threat Distinguish good traffic from bad traffic Block bad traffic while still allowing good traffic through.  Protect all points of vulnerability.

7 Prevention Methods  Blackholing  Overprovision  Routers  Firewalls  Intrusion Detection Systems (IDS)  Third Party Protection

8 Blackholing  Blocking all traffic the network as far upstream as possible.  Traffic is diverted to a “black hole” where it is discarded.  Good and bad packets are discarded. Not an efficient solution to a DDoS attack. Attacker’s objective is still fulfilled.

9 Firewalls  Not purpose-built for DDoS attacks, but provide some protection.  Reside too far downstream in the network.  Lack of anomaly detection, can’t recognize when valid protocols are being used in an attack.  Cannot perform antispoofing on a packet by packet basis.

10 Third Party Protection  DNS based redirect service.  Border Gateway Protocol (BGP) based service.  Content Delivery Network (CDN) providers.

11 History of Attacks  Anonymous Hacktivist Group (Civil Disobedience)  Lizard Squad PlayStation 4 Network, Xbox Live, Facebook  GitHub Attack Chinese Government, Replaced JS Code to Force reload pages  Happening Now Digital Attack Map
