Abstract
Background & Objective:
Detecting and mitigating Distributed Denial of Service (DDoS)
attacks is a serious problem. In addition, new features and network deployments such as Software-
Defined Networking (SDN) may open the door for new threats that did not previously exist.
:
Recent publications and patent are reviewed to find new techniques developed for integrating different
mechanisms to secure networks against DDoS.
Methods:
This work presents a simple model for integrating different mechanisms to secure both
SDN and legacy network in a hybrid cloud environment, it is called FocusON. It aims at mitigating
DDoS attacks of a victim network. In addition, separating network monitoring from its control aims
at mitigating DDoS attacks of a victim network. Traffic pattern analysis is apart from attack detection
mechanism that gives a conceptual representation of a specific kind of DDoS attacks. DDoS detection
is a completely automated process. Once called, for the reaction, the active response will be taken
against the real IP source of the attacker.
:
The communication time overhead was tested in order to evaluate the remote server response time in
case of deploying our proposed model mechanisms and without our proposed model.
:
Here we introduce a response mechanism that consists of an analysis of event logs, traffic patterns,
and IP traceback. The proposed model categorizes the underlying network according to the location
into a victim network and the source of attack (public cloud).
Results & Conclusion::
The proposed model implemented in a hybrid cloud environment using the
network of SDN and legacy network. The experimental setup was built using our network lab connected
to the Amazon public cloud.
