Grid is an emerging technology that aims at utilizing resources efficiently and effectively, A botnet is a collection of infected computers and the common attacks are A Distributed denial of service attack (DDOS) is any type of attack on a networking structure to disable a server from servicing its clients. Attacks range from sending millions of requests to a server in an attempt to slow it down, flooding a server with large packets of invalid data, to sending requests with an Invalid or spoofed ip address. A botnet is taking action on the client itself via IRC Channels without the hackers having to login to the clients computer. In this paper we show the implementation and analysis of three main types of attack: Ping of Death, TCP SYN Flood, and Distributed DOS. The Ping of Death attack will be simulated against a Microsoft Windows xp, computer. The TCP SYN Flood attack will be simulated against a Microsoft Windows 2007 IIS FTP Server. Distributed DOS will be demonstrated by simulating a distribution zombie program that will carry the Ping of Death attack. This paper focuses on improving the efficiency of the system performance over the network by implementing algorithm, It demonstrate the potential damage from DOS attacks and analyze the ramifications of the damage.

Web application distributed denial-of-service attack (Web-App DDoS Attack) is a common dangerous attack that hackers use to attack the information systems of organizations. Web application is often hackers' target because this kind of application is an external interface of an organization to provide the organization's activities services. In addition, due to the emergence of weaknesses and security holes in applications and operating systems, hackers can easily create a large-scale botnet for more effective Web-App DDoS Attack. In fact, there have been many research projects related to the defense against this type of attack. However, DDoS attacks still cause serious damage to the systems of organizations due to the fact that the attack methods are increasingly sophisticated and constantly changing. In this study, we propose a method for Web-App DDoS Attack mitigation on the basis of analyzing the relationship among the requests sent to the Web application to find out the source IP address of malicious requests and to perform mitigation. Our method provides a set of criteria that allows determining whether a source IP address is normal or malicious in a short period of time. The criteria also make it difficult for hackers to change the attack methods to overcome the characteristics of the criteria.

CGA binds the IPv6 address with multiple auxiliary parameters, thereby making the dependency relationship between IPv6 address and host provable, which prevents address embezzlement. Owing to the considerable overhead in CGA parameter verification, the malicious host can use this point to carry out DoS attacks. To prevent DoS, the paper proposes a new duplicate address detection method in an SDN environment called FDAD. Two additional mechanisms are added to the FDAD, namely, query and feedback; messages used by the new mechanisms are also designed. Through these two mechanisms, on the one hand, the host can query the MAC address of the suspect host to the controller. On the other hand, if the CGA parameter verification fails, the controller will use feedback information to suppress malicious host from its source port in order to prevent subsequent attacks. Experiments show that the CPU overhead of FDAD is much lower than the normal CGA when suffering Denial of Service attack. The increased CPU consumption and memory overhead of the controller are also within acceptable range, and the network communication overhead is greatly reduced.

With the dramatic evolution in networks nowadays, an equivalent growth of challenges has been depicted toward implementing and deployment of such networks. One of the serious challenges is the security where wide range of attacks would threat these networks. Denial-of-Service (DoS) is one of the common attacks that targets several types of networks in which a huge amount of information is being flooded into a specific server for the purpose of turning of such server. Many research studies have examined the simulation of networks in order to observe the behavior of DoS. However, the variety of its types hinders the process of configuring the DoS attacks. In particular, the Distributed DoS (DDoS) is considered to be the most challenging threat to various networks. Hence, this paper aims to accommodate a comprehensive simulation in order to figure out and detect DDoS attacks. Using the well-known simulator technique of NS-2, the experiments showed that different types of DDoS have been characterized, examined and detected. This implies the efficacy of the comprehensive simulation proposed by this study.

As the ubiquitous computing environment gets more attention and development, WSN (Wireless Sensor Network) is getting popular as well. Especially, the development of wireless communication and sensor equipment greatly contributes to the popularization of WSN. On the other hand, the safety and security of WSN attracts lots of attention due to such a development and distribution. The DoS (Denial of Service) attack, which gets more sophisticated and broadens its domain into various services fields, may have negative effects on WSN, making it vulnerable to attacks. Since WSN collects information through sensors that are already deployed, it is difficult to have its energy recharged. When WSN is under a DoS attack, sensor nodes consume lots of energy, bringing about a fatal result to the sensor network. In this paper, we propose a method to efficiently defend against DoS attacks by modifying routing protocols in the WSN. This method uses a location based routing protocol that is simple and easy to implement. In the WSN environment where the location-based routing protocol is implemented, this method disperses the DoS attack concentration of traffic by using the traffic deflection technique and blocks it out before arriving at the target destinations. To find out the number of traffic redirection nodes proper for this method, we have performed a few experiments, through which the number of such nodes was optimized.

In computing, a denial-of-service attack (DoS attack) is a cyber-attack where the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. This effectively makes it impossible to stop the attack simply by blocking a single source. In this research a generalized model for detection has been created by studying the existing models and algorithms on DoS attacks. Internet security is vital to facilitate e-commerce transactions, and there has been continued research effort to provision network traffic monitoring at high speeds. In the proposed technique a threshold is also defined so that any other node id which is greater than that threshold may be prevented. In case of any intrusion IP backtracking and packet logging is used to detect the intruder and mitigate it. From result it may be clear that the QoS parameters are improved using proposed approach and there are improved by approx 15-18% from the existing approach.

A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a machine or network resource unavailable to its intended users. In this paper, a new technique for detecting DoS attacks is proposed; it detects DOS attacks using a set of classifiers and visualizes them in real time. This technique is based on the collection of network parameter values (data packets) which are automatically represented by simple geometric graphs form in order to highlight relevant elements. The effectiveness of the proposed technique has been proven through a MATLAB simulation of network traffic drawn from the 10% KDD, and a comparison with other classification techniques for intrusion detection.
