....A victim can be a host, server, router, or any computing entity connected to the network. Inevitable human errors during software development, configuration, and installation open several unseen doors for these type of attacks. Several DoS attacks are known and documented in the literature [14, 16, 21, 24]. Flooding a victim with an overwhelming amount of traffic is the most common. This unusual traffic clogs the communication links and thwarts all connections among the legitimate users, which may result in shutting down an entire site or a branch of the network. This happened in February of 2000 ....

....This unusual traffic clogs the communication links and thwarts all connections among the legitimate users, which may result in shutting down an entire site or a branch of the network. This happened in February of 2000 for the popular web sites Yahoo, E trade, Ebay, and CNN for several hours [14]. TCP SYN flooding is an instance of the flooding attacks [22] Under this attack, the victim is a host and usually runs a Web server. A regular client opens a connection with the server by sending a TCP SYN segment. The server allocates buffer for the expected connection and replies with a TCP ....

....identify and then discard close to 90 of spoofed IP packets with little collateral damage. We implement and evaluate the HCF in the Linux kernel, demonstrating its benefits with experimental measurements. 1 Introduction DDoS attacks pose a serious threat to the availability of Internet services [4, 15, 25]. Instead of subverting services, DDoS attacks limit and block legitimate users access by exhausting victim servers resources [5] or saturating stub networks access links to the Internet [16] To conceal flooding sources and localities of flooding traffic, attackers spoof IP addresses by ....

....because of device failures (for e.g. link and node failures) or because of the presence of malicious users or hackers . The importance of securing the Internet has grown rapidly due to a series of attacks that shut down some of the world s most high profile Web sites, including Amazon and Yahoo [2]. Several such attacks have also been reported in CERT advisories [3] These attacks, coupled with the growing fear of cyber terrorism have made researchers think of possible ways of compromising the Internet, and means and methods to protect users from the adversaries. Figure 1 lists out the ....

....Our studies show that the PAIR is extremely scalable and offers high detection and recovery capability. I. INTRODUCTION The importance of securing the Internet has grown rapidly due to a series of attacks that shut down some of the world s most high profile Web sites, including Amazon and Yahoo [1] and due to the growing concerns of cyber terrorism. Internet attacks can be mainly categorized into four types [2] i) Routing Table Poisoning Attacks (ii) Packet Mistreating Attacks (iii) Denial of Service Attacks and (iv) DNS Hacking Attacks. Routing is among the most critical functions ....

....of the flooding sources without resorting to expensive IP traceback. I. INTRODUCTION The recent attacks on popular web sites like Yahoo, eBay and E Trade, and their consequent disruption of services have exposed the vulnerability of the Internet to Distributed Denial of Service (DDoS) attacks [12]. It has been shown that more than 90 of the DoS attacks use TCP [19] The TCP SYN flooding is the most commonly used attack. It consists of a stream of spoofed TCP SYN packets directed to a listening TCP port of the victim. Not only the Web servers but also any system connected to the Internet ....

INTRODUCTION The growing DDoS attacks have imposed a significant threat on the availability of network services [12]. Due to the readily available tools and its simple nature, flooding packets is the most common and effective DoS attack. More than 90 of the DoS attacks use TCP [18] and TCP SYN flooding dominates in the available attacking tools and the number of known DoS attacks [16] The SYN flooding ....

....(2) no service differentiation and resource isolation are provided to meta data packets such as TCP SYN and ACK packets. Moreover, the coarse grained service differentiation and the lack of resource isolation at IP routers exposes its vulnerability to Distributed Denial of Service (DDoS) attacks [10]. Based on the concept of layer 4 service differentiation and resource isolation, where the transport layer information is inferred from the IP headers and used for packet classification and resource management, we present a scalable fine grained DiffServ (sf DiffServ) architecture that provides ....

....generation of DoS attacks, such as TCP SYN and ACK flooding attacks. In other words, the coarse grained service differentiation and the lack of resource isolation on meta data packets not only degrade the assured service of TCP sessions but also expose the vulnerability of Internet to DDoS attacks [10]. In this paper, we propose a scalable fine grained DiffServ (sf DiffServ) architecture to provide fine grained service differentiation and resource isolation among thinner aggregates without compromising scalability. The basic concept employed is layer 4 service differentiation and resource ....

A series of DDoS attacks occurred in February 2000 to considerable media attention, resulting in higher packet loss rates in the Internet for several hours [12].

This particular type of attack also exploits design or configuration faults in the many Internet connected hosts that were penetrated to insert the zombie daemons required to mount a coordinated distributed attack [Garber 2000]. A third vulnerability, which prevents effective countermeasures from being launched, resides in a design fault on the part of Internet service providers not implementing ingress egress filtering (which would enable the originating IP source address to be traced) Let us now return to the notion ....

....scheduled without producing unacceptable delay in service delivery for the other clients. In the latter case, all useful server resources are deviated to satisfy unauthorized and malicious operations, so to make the server unavailable to meet other more significant and proper operation requests [Gar 00] The prevention of DoS attacks is even more crucial in systems likely to host execution of external programs, such as in MA environments. In MA systems, the advantages of uploading external code to dynamically extend and tailor server operations means also to open server execution resources to ....
