-Distributed denial of service (DDoS) attack is ongoing dangerous threat to the Internet. Commonly, DDoS attacks are carried out at the network layer, e.g., SYN flooding, ICMP flooding and UDP flooding, which are called DDoS attacks. The intention of these DDoS attacks is to utilize the network bandwidth and deny service to authorize users of the victim systems. Obtain from the low layers, new ...

SYN flooding attacks are very common types of attacks in IP (Internet Protocol) based networks. It is a type of Denial of Service Attack in which attacker sends many SYN request with spoofed source address to a victim’s machine. Each request causes the targeted host to allocate data structures out of a limited pool of resources. After some time the targeted host goes out of resources and cannot...

Service on-demand (SoD) systems allow their users to regulate the sharing of common resources via a voting process. A common application example is the collaborative scheduling of multimedia transmissions in e-radio or video streaming services. Therefore, high user commitment and participation is critical to the success of a SoD system. Securing a SoD system against common attacks, such as vote...

The Internet Threat Monitoring (ITM) is an efficient monitoring system used globally to measure, detect, characterize and track threats such as denial of service (DoS) and distributed Denial of Service (DDoS) attacks and worms. . To block the monitoring system in the internet the attackers are targeted the ITM system. In this paper we address the flooding attack of DDoS against ITM monitors to ...

As the Internet becomes increasingly important as a business infrastructure, the number of attacks on it, especially denial-of-service attacks such as TCP SYN flooding,1 Teardrop,2 and Land,2 grows. Because of the weak security in TCP/IP, we must take responsibility for protecting our own sites against network attacks. Although access-control technologies, such as firewalls, are commonly used t...

Without the management of centralized unit, mobile ad hoc networks (MANETs) are vulnerable to security threats from flooding attacks launched through compromised nodes or intruders. When a source node needs a data session with a destination node, it disseminates a route request (RREQ) message to its neighbors in a hop-by-hop manner. One crucial type of flooding attacks called RREQ flooding appe...
