Countermeasure Tool - Carapace for Network Security

Abstract

Now a day frequency of attacks on network is increased. In this, denial of services (DOS) and IP spoofing are more common. It is very difficult to find out these attacks. Denial of services (DOS) and its type Distributed denial of services (DDOS) are significant problem because it is very hard to detect it. Its main aim to shut resource from internet, and make resource unavailable to legitimate users. IP source address forgery, or “spoofing,” is a long-recognized consequence of the Internet’s lack of packet-level authenticity. IP spoofing is very powerful when it implemented with Distributed denial of services (DDOS). In this paper we deal with the information gathering process to do attacks. The information gathering about the weaknesses of the target system and helps to do attack. Lastly we proposed a new model to protect from attacks.
