It aims at disrupting the application service rather than depleting the network services. These possess severe threat to Internet Security. Detection and prevention of these attacks are harder compared to classic dos attacks. These attacks have high similarity with legitimate traffic so tracing the attack origin is more difficult. We proposed a new novel Group testing which provide short detection delay and low false positive/negative rate. We propose a two mode detection mechanism using some dynamic threshold for identifying the attackers efficiently. Index terms: group testing, Denial of Service attack (Dos), Internet Security. 1. Introduction: Internet has become a integral part of everybody’s life. Our daily routines like banking, transport, health, etc., are dependent upon internet partially or completely. People connecting to internet have increasing by exponential rate over the few years. With approximately people connecting to internet and with 1 billion searches on google [1]. Any inconvenience in these services can cost us significantly. Denial of service attacks(Dos) which aims at legitimate users, clients, customers from successfully accessing the internet has posing a serious challenge to the network security. Application Dos attacks is a new class of Dos attacks which exploits the flaws in either application design or .
