Resisting Proxy-Based Attacks Based On Temporal and Spatial Locality Behaviour

Sai Subha.V, Arathi Gandhi

In computer networks, a proxy server is a server that may be a computer system or an application that acts as an intermediary for requests from clients seeking resources from other servers. In this paper, it mainly focuses to resist proxy-based DDOS attacks. It extracts the behavior features of traffic from proxy to server based on temporal and spatial locality. A hidden semi-markov model is used to describe traffic behavior of proxy to server. Here, it assessed the shortterm behavior for improving quality of services of normal users. It converting suspicious sequence into normal one by discarding most illegimate request, instead of discarding entire sequence.
