Crytography Bases Solution FOR Distributed Denial of Service Attack in Manet

Distributed Denial of Service Attack Detection in Wireless Sensor Networks

Wireless sensor networks have emerged as a significant source for the study and analysis of data from the environment. These networks are deployed in harsh and inaccessible environments with the purpose of monitoring their respective surroundings, and generating observed readings, for delivery to a centralised entity, for further data analysis. Sensor nodes are tiny devices with limited availab...

Denial Of Service Attacks In MANET

Mobile Ad Hoc Network (MANET) consists of several devices, nodes or terminals which are connected wirelessly and capable to communicate with each other nodes without any pre-existing infrastructure. MANET is considered as autonomous system were mobile hosts are connected using wireless links and free to be dynamic were configuration may change time to time. The nodes in the MANET have the liber...

Distributed Denial of Service Defense Attack Tradeoff Analysis (DDOS-DATA)

WDA: A Web farm Distributed Denial Of Service attack attenuator

Distributed Denial Of Service (DDoS) attacks are familiar threats to Internet users for more than ten years. Such attacks are carried out by a “Bot net”, an army of zombie hosts spread around the Internet, that overwhelm the bandwidth toward their victim Web server, by sending traffic upon command. This paper introduces WDA, a novel architecture to attenuate the DDoS attacker’s bandwidth. WDA i...

Defeating distributed denial-of-service attack with deterministic bit marking

Denial-of-Service (DDoS) attack is a serious threat in Internet. We propose a bit marking concept to identify and drop the DDoS attack packets. Bit marking is a variation of the packet marking technique that modifies packet headers at each router. However instead of storing the router information in the packets, bit marking alters one or more bits in the marking field. The bit marking process d...
