Distributed denial-of-service (DoS) attacks present a great threat to the Internet, and
existing security mechanisms cannot detect or stop them successfully. The problem lies
in the distributed nature of attacks, which engages the power of a vast number of
coordinated hosts. To mitigate the impacts of DDoS attacks, it is important to develop
such defenses system that canbothdetect andreact against ongoing attacks. The attacks
ideally should be stopped as close to the sources as possible, saving network resources
andreducing congestion. The DDoS defense system that is deployed at the source-end
should prevent the machines at associated network from participating in DDoS attacks.
The primary objective of this project, which is developing a DDoS defense system, is to
provide good service to a victim's legitimate clients during the attack, thus canceling
the denial-of-service effect. The scope of study will coverthe aspect of howthe attack
detection algorithms work and identify the attack traffic, hence develop appropriate
attack responses. As a source-end defense against DDoS attacks, the attack flows can be
stopped before they enter the Internet core and before they aggregate with other attack flows.
The methodology chosen for this project is the combination of sequential and iterative
approaches of the software development process, which comprises of six main phases,
which are initial planning phase, requirement definition phase, system design phase,
coding and testing phase, implementation phase, and lastly maintenance and support
phase. The system used a source router approach, in which the source router serves as a
gateway between the source network containing some of the attack nodes and the rest of the
Internet, to detectand limitDDoS streams long before they reach the target. This will be
covered in the Findings section of the report. TheDiscussion section will be focus more onthe
architecture onthe system, which having three important component; observation, rate-limiting
and traffic-policing.
