چکیده

Web-sites acts as the best platforms for attacks like DDOS attack worm propagation and many other attacks which are related to application layer. To detect application layer DDOS attack is a cumbersome task. It is basically originated from the lower layer i.e. network layer and transport layer. Whereas this new application layer based DDOS attacks utilizes genuine HTTP request to make victim resources busy somewhere else which are undetectable. Various tools like hyenae, strut, LOIC, HOIC etc have been used to see the scenario of DDOS attack on various websites. Distributed framework helps to increase the quality of response for genuine traffic under DDOS attacks. A distributed solution is required for the distributed nature of DDOS attack. Hence we will propose architecture for the defense which can efficiently detect these attacks. The behaviors of packet flows will be analyzed. Entropy based detection and trace back algorithm will be used, which efficiently distinguish the malicious flows from the legitimate flows. This work includes simulation and their performance analysis of our proposed framework.

F-STONE: A Fast Real-Time DDOS Attack Detection Method Using an Improved Historical Memory Management

Distributed Denial of Service (DDoS) is a common attack in recent years that can deplete the bandwidth of victim nodes by flooding packets. Based on the type and quantity of traffic used for the attack and the exploited vulnerability of the target, DDoS attacks are grouped into three categories as Volumetric attacks, Protocol attacks and Application attacks. The volumetric attack, which the pro...

Neural Network Based Protection of Software Defined Network Controller against Distributed Denial of Service Attacks

Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...

Shuffling Based Mechanism for DDoS Prevention on Cloud Environment

Cloud Computing has evolved as a new paradigm in which users can use on-demand services, according to their needs. However, security concerns are primary obstacles to a wider adoption of clouds. Newly born concepts that clouds introduced, such as multitenancy, resource sharing and outsourcing, create new challenges for the security research. DDoS (Distributed Denial of service) attack is the bi...

Low-rate DDOS Attack Detection using Optimal Objective Entropy Method

A Distributed Denial of Service (DDOS) attack is a type of Internet attack that disrupts the normal function of the targeted computer network (server). This kind of attacks attempts to make target host resource unavailable to its legal users. Several efforts had made in detection and computation of the DDOS attacks over network, where IDS (Intrusion detection systems) are unable to isolate the ...

E-LDAT: a lightweight system for DDoS flooding attack detection and IP traceback using extended entropy metric

Distributed denial-of-service (DDoS) attacks cause havoc by exploiting threats to Internet services. In this paper, we propose E-LDAT, a lightweight extended-entropy metric-based system for both DDoS flooding attack detection and IP (Internet Protocol) traceback. It aims to identify DDoS attacks effectively by measuring the metric difference between legitimate traffic and attack traffic. IP tra...
