Network Intrusion Detection and Countermeasure Selection in Virtual Network Systems

Abstract

Cloud security is one of most important issue last few years.Particularly, attackers canexplore
vulnerabilities of a cloud system and. A distributed denial-of-service (DDoS) attack occurs when multiple systems
flood the bandwidth or resources of a targeted system, usually one or more web servers. In such attack attacker uses
one or more agents to attack the actual server service.we proposed a concept of NICE which recognizes different
kind of attacks based on different countermeasure. The proposed system builds client-server architecture in which
an attacker can perform different types of attacks and nice agent can determine those with relative countermeasures
