The invention of the internet environment has increased the speed of data transmission, however, the attacks in this environment are growing exponentially. Furthermore, identifying the source of the attacks is very difficult due to the vibrant and ...

Distributed denial of service, DDoS, attacks are drastically increasing, therefore, they cause serious threats for information networks. This paper proposes, for the first time, the use of a graph theoretic approach to exploit the entropy techniques for ...

Extending fairness to multiple timescales creates the right incentives for users and provides better QoE for short sessions, e.g. for web page download. In this paper, we show how to define and implement multi-timescale fairness among flows independently ...

Increasing number of digital crime raises the need of investigation where the most critical step is to collect the evidences of attack and find the real origin of the attack. However the attacker can easily spoof the source IP address and hence the ...

Resource exhaustion attacks or denial of service attacks (DoS) have emerged as a major way to compromise the availability of servers and interrupt legitimate online services. IP trace back refers to the problem of identifying the source of such attacks. ...

Network-based attacks such as denial-of-service attacks are usually performed by spoofing the source IP address. Packet marking techniques are used to trace such attackers as close as possible to their source. A packet mark consists of some traceback ...

Internet Protocol (IP) trace back is the technology to give security to internet and secure from the internet crime. IP trace back system is also called as Flexible Deterministic Packet Marking (FDPM) which builds such a defense mechanism which has ...

Defences against Denial and Distributed Denial of Service (DDoS) attacks commonly responds to flooding by dropping excess traffic. Such rate limiting schemes drop all excess-traffic when the request arrival rate goes above a certain empirically ...

Currently, the main threats of network security are coming from hacker intrusion, deny of service (DoS), computer virus, worm, spam, malicious code and sniffer because there are many weaknesses in the original design of IPv4. One is that attackers could ...

In a hostile environment, sensor nodes may be compromised and then be used to launch various attacks. One severe attack is false data injection which is becoming a serious threat to wireless sensor networks. An attacker uses the compromised node to ...

Internet crimes such as DDoS attack have seriously affected the businesses that have dependencies on computer networks such as the Internet. However, TCP/IP based networks have no protection against malicious packet modifications and attackers do ...

Ever increasing rate of Denial of Service (DoS) attacks presents severe security threats to the internet. In this study, a backpressure scheme to filter DoS attack traffic at the earliest possible is presented. This paper utilises markings stamped in ...

This article studies a kind of new advanced packet marking method through analyzing the problems existing in traditional advanced packet marking method. This method has made it unnecessary for the victim to know the network topological information of ...

Based on the principle of divide and conquer, in this paper we propose an efficient traceback protocol for mobile ad hoc networks, The protocol is capable of detecting a hotspot where the attacker resides. It works by dividing the forwarding path of ...

IP traceback is a mechanism for tracing IP packets back to their sources. Tracing mechanisms include packet marking and logging. Log based traceback has the ability to backtrack a single packet by logging each packet at intermediate nodes in the ...

The technique of IP traceback is used to overcome Denial-of-Service attacks. This paper deals with explaining the two types of IP traceback techniques namely, Packet Marking and Packet Logging which have been proposed earlier. The paper further explains ...

In the light of that the defense against DDoS attacks is difficult, an active DDoS defense model based on packet marking is proposed in this paper. The model is composed of the subsystem of the tracking of the attacks and the subsystem of filtering of ...

The basis of denial of service (DoS)/distributed DoS (DDoS) attacks lies in overwhelming a victim's computer resources by flooding them with enormous traffic. This is done by compromising multiple systems that send a high volume of traffic. The traffic ...

Classical firewalls provide network security by matching a network flow's 5-tuple information against user defined packet filters loaded into memory. In today's dynamic network environments where threats can be both outside and inside a network, it is ...

Detecting and defeating Denial of Service (DoS) attacks is one of the hardest security problems on IP networks. Furthermore, spoofing of IP packets makes it difficult to combat against and fix such attacks. Packet marking is one of the methods to ...
